Title of the Trial:
Safety and Immunogenicity of Fluzone® Quadrivalent Vaccine 
Administered to Healthy Children 6 to < 36 Months of Age
Development Phase:
Phase IV
Coordinating Investigator:
To be determined
Trial Centers:
This will be a multi-center trial conducted in the United States. 
Investigators and sites are listed in the “List of Investigators, Trial Centers, 
and Sponsor’s Personnel Involved in the Trial” document.
Planned Trial Period:
First Visit, First Subject: September 2016
Last Visit, Last Subject: February 2017
Trial Design and Methodology:
This will be a Phase IV, randomized, observer-blinded, 2-arm, multi-center 
trial of approximately 2190 subjects 6 to < 36 months of age. 
Using a pre-programmed interactive response technology (IRT) system, 
subjects will be randomly assigned in a 1:1 ratio to either 1 of the following 
groups:
Group 1: 0.25 mL of Fluzone Quadrivalent vaccine (approximately 1095 
subjects)
Group 2: 0.5 mL of Fluzone Quadrivalent vaccine (approximately 1095 
subjects) 
Enrollment will be stratified by age at each site so that approximately 50% of 
subjects at each site will be 6 to < 24 months of age and approximately 50% 
of subjects at each site will be 24 to < 36 months of age. If necessary to 
achieve 50% overall enrollment of subjects 6 to < 24 months of age, 
individual sites may be permitted to deviate from this ratio. 
All subjects will receive 1 intramuscular dose of Fluzone Quadrivalent 
vaccine during Visit 1. For subjects for whom 2 doses of influenza vaccine 
are recommended per the Advisory Committee on Immunization Practices 
(ACIP) guidance, a second dose of Fluzone Quadrivalent vaccine will be 
administered during Visit 2 (28 [window, 28–35] days after Visit 1). Blood 
specimens will be obtained from a planned subset of 1600 subjects randomly 
selected by an IRT system (half in Group 1 and half in Group 2) prior to the 
first vaccination and 28 (window, 28–35) days following the final 
vaccination (Visit 2 for subjects receiving 1 dose; Visit 3 for subjects 
receiving 2 doses) and assayed for immunogenicity.
Solicited adverse event (AE) information will be collected for 7 days after 
each vaccination. Unsolicited AE information and serious adverse event

(SAE) information will be collected from Visit 1 to Visit 2 for subjects 
receiving 1 dose or from Visit 1 to Visit 3 for subjects receiving 2 doses. 
Note: Any SAE that occurs after a subject has completed the study but that is 
likely to be related to the product is to also be reported to the Sponsor.
The subject, Investigator, study site personnel, and Sponsor’s clinical team 
members involved in the trial will be blinded to the vaccine dose 
administered, with the exception of 1 or more unblinded qualified study staff 
members who will administer the vaccine. The unblinded qualified study 
staff will not participate in the collection of safety data.
Early Safety Data Review:
This trial will not include an early review of safety data. However, it may be 
interrupted at any time if new data about the investigational product become 
available, and/or on advice of the Sponsor, the Institutional Review Board(s) 
(IRB[s]), or the Food and Drug Administration (FDA). 
If the trial is prematurely terminated or suspended, the Sponsor will promptly 
inform the Investigators, the IRB(s), and the FDA of the reason for 
termination or suspension. If the trial is prematurely terminated for any 
reason, the Investigator will promptly inform the trial subjects’ 
parents/guardians and should assure appropriate therapy for and follow-up of
subjects.

age.
Hypothesis: 
During the 7 days after either vaccination (Dose 1 and Dose 2 combined), the 
0.5-mL dose of Fluzone Quadrivalent vaccine will be non-inferior to the 
0.25-mL dose of Fluzone Quadrivalent vaccine in terms of fever reaction

Secondary Objective:
To compare antibody responses induced by the 0.5-mL dose of Fluzone 
Quadrivalent vaccine to those induced by the 0.25-mL dose of Fluzone 
Quadrivalent vaccine as assessed by geometric mean titer (GMT) ratios and 
seroconversion rate differences after the final vaccination in subjects 6 to 
< 36 months of age.
Hypotheses:
Geometric mean titers: For each of the 4 virus strains, the post-final 
vaccination GMTs in subjects 6 to < 36 months of age who receive the 
0.5-mL dose of Fluzone Quadrivalent vaccine will be non-inferior to the 
post-final vaccination GMTs in those subjects who receive the 0.25-mL dose 
of Fluzone Quadrivalent vaccine.
Seroconversion: For each of the 4 virus strains, the seroconversion rates in 
subjects 6 to < 36 months of age who receive the 0.5-mL dose of Fluzone 
Quadrivalent vaccine will be non-inferior to the seroconversion rates in those 
subjects who receive the 0.25-mL dose of Fluzone Quadrivalent vaccine.

0.5-mL dose as administered at Visit 1) will be administered at Visit 2. 
Blood Sampling
A total of 2 blood samples of approximately 5 mL each will be collected 
from a planned subset of 1600 subjects randomly selected by an IRT system 
(half in Group 1 and half in Group 2). 
The first blood sample will be collected at Visit 1 prior to vaccination. The 
second blood sample will be collected at Visit 2, if no study vaccine is 
administered at Visit 2; or at Visit 3, if study vaccine is administered at 
Visit 2.
Study sites, at their discretion, may apply a topical analgesic to the 
venipuncture site prior to obtaining sera. However, topical analgesic agents 
must not be applied at the site of vaccine administration.
Collection of Safety Data
Staff will observe subjects for 20 minutes following vaccine administration 
and will record the occurrence of any immediate unsolicited systemic AEs.
Parents/guardians will record information about solicited injection site and

Statistical  Methods:
Summaries of the recruitment and baseline demographic characteristics of 
the study subjects will be presented. The number of subjects enrolled and 
their age at enrollment (mean, median, and minimum and maximum), sex, 
race, and ethnic origin will be summarized, along with the number and 
description of protocol violations.
Continuous variables will be summarized by descriptive statistics (e.g., 
means and standard deviations for the non-immunogenicity endpoints, and 
geometric means and their confidence intervals [CIs] for the 
immunogenicity endpoints); categorical variables will be summarized by 
frequency distributions (frequency counts, percentages, and their CIs for the 
main endpoints).
Primary Objective: Safety
The 0.5-mL dose of Fluzone Quadrivalent vaccine will be demonstrated as 
non-inferior to the 0.25-mL dose of Fluzone Quadrivalent vaccine in terms 
of fever reaction through an assessment of the rates of any fever 
WHPSHUDWXUH)>oC]) during the 7 days following any dose 
(Dose 1 and Dose 2 combined). Non-inferiority will be demonstrated if the 
upper bound of the 2-sided 95% CI of the rate difference between Group 2
(subjects receiving 0.5 mL of vaccine) and Group 1 (subjects receiving 0.25 
mL of vaccine) is < 5%. The 95% CI of the rate difference will be computed 
using the Wilson Score method without continuity correction. The Safety 
Analysis Set will be used for this objective.
Secondary Objective: Immunogenicity
Geometric mean titers: The statistical methodology will be based on a 
2-sided 95% CI of the ratio of the GMTs (0.5-mL dose divided by 0.25-mL 
dose) at 28 (window, 28–35) days after the final vaccination.  Non-
inferiority for GMTs will be demonstrated if the lower limit of the 2-sided 
95% CI of the GMT ratio is > 0.667 for each of the 4 virus strains. The 95%
CI will be calculated using normal approximation of log-transformed titers.
The Per-Protocol Analysis Set (PPAS) will be used as the primary analysis 
set for this objective.
Seroconversion: The statistical methodology will be based on a 2-sided 
95% CI of the difference in seroconversion rates (0.5-mL dose minus 0.25-
mL dose) at 28 (window, 28–35) days after the final vaccination. Non-
inferiority for seroconversion will be demonstrated if the lower limit of the 
2-sided 95% CI is > -10% for the 4 strains. The 95% CI of the rate 
difference will be computed using the Wilson Score method without 
continuity correction. The PPAS will be used as the primary analysis set for 
this objective.

Introduction
1.1
Background
This is a trial using the 2016–2017 formulation of quadrivalent inactivated influenza vaccine 
(Fluzone® Quadrivalent, Influenza Vaccine). 
Influenza viruses types A and B belong to the genus Orthomyxoviridae and are characterized as 
enveloped, negative-strand, segmented RNA viruses. The viral envelope contains 2 virus-coded 
glycoprotein spikes, the hemagglutinin (HA) and neuraminidase (NA) proteins, which are key 
antigens in the host response to influenza virus in both natural infection and vaccination. A third 
protein, M2, is a minor envelope component of the A-strain viruses (1) (2).
Influenza is transmitted through inhalation of virus-containing droplets from infected individuals. 
The incubation period is usually 1 to 2 days (3). The virus multiplies in the ciliated columnar 
epithelium of the upper- and lower-respiratory tract, causing cellular necrosis and sloughing (2).
Virus shedding typically begins just before illness onset (within 24 hours), rapidly peaks, and 
remains elevated for 1 to 2 days before rapidly declining to low levels. Usually, virus shedding 
lasts a total of 5 to 10 days (3).
There is considerable variation in the severity of illness in different individuals, partly due to age, 
general health, and immune status relative to previous influenza infections. The classic symptoms 
include rapid onset (12 hours or less) of malaise, fever, myalgia, headache, and a non-productive 
cough or sore throat. Most symptoms last several days, but malaise and cough may last for a week 
or more (3). Complications of influenza include primary viral pneumonia, secondary bacterial 
pneumonia, and exacerbation of underlying medical conditions such as chronic obstructive 
pulmonary disease and congestive heart failure.
While influenza affects all age groups, the elderly and persons with underlying health problems 
are at increased risk for complications. Members of high-risk groups who become ill with 
influenza are more likely than the general population to require hospitalization. Among infants 
and younger children, estimated rates of influenza-associated hospitalization are substantially 
higher than among older children and are similar to rates for other groups considered at higher 
risk for influenza-UHODWHGFRPSOLFDWLRQVLQFOXGLQJSHUVRQVDJHG 65 years (1).
Antigenic variation is an important feature of the influenza virus. The viral HA and NA surface 
antigens are subject to continuous and sequential evolution within immune or partially immune 
populations. Antigenic drift results from mutation(s) affecting the RNA segment coding for either 
HA or NA, but more commonly HA. As a result, there is alteration in protein structure involving 
1 or a few amino acids, resulting in minor changes in antigenicity. Antigenic variants within a 
subtype (e.g., H1 or H3) emerge and through natural selection gradually become the more 
predominant circulating virus strain, while the preceding antigenic variant is suppressed by 
specific immunity in the population. In contrast to antigenic drift, antigenic shift represents the 
emergence of completely new subtypes, typically through gene reassortment with other 
circulating strains and acquisition of antigenically different gene sequences. Antigenic shift 
occurs at irregular intervals and may lead to pandemics (2) (3). While influenza B appears to be 
more genetically stable than influenza A, the dominant circulating B strain typically varies from

season to season. For over a decade, both Yamagata and Victoria lineages have co-circulated
during each season with varying prevalence (4). The large antigenic divergence between the 
2 influenza B lineages limits antigenic cross-reactivity, and immunity to influenza viruses of 
1 B lineage may not provide adequate protection against viruses of the other lineage. Accordingly, 
switching from a trivalent vaccine to a quadrivalent vaccine is expected to prevent additional 
morbidity and mortality associated with influenza B (4). With this in mind, Fluzone Quadrivalent 
vaccine was developed.
1.1.1
Epidemiology
Influenza is noted for occurring in epidemics. Typically, localized influenza epidemics begin
abruptly, peak in 2 to 3 weeks, and last 5 to 6 weeks. The first sign of influenza in the community 
is usually reports of increased numbers of children with febrile respiratory illness, although a 
nursing home outbreak may be the first indication. Outbreaks in children are usually followed by 
the occurrence of influenza-like illness among adults. Following this is an increase in hospital 
admissions for pneumonia, exacerbation of chronic obstructive pulmonary disease, croup, and 
congestive heart failure. Increased absenteeism from school and the workplace occurs as a late 
indicator. Finally, an increased number of deaths due to pneumonia and influenza are a highly 
specific indicator of influenza. However, due to the reporting delay and time course from 
infection to death, this indicator lags behind the others (3).
As with other viral respiratory infections, influenza is a seasonal disease. In the Northern 
Hemisphere, influenza is most likely to occur from November to April, and in the Southern 
Hemisphere from May to October. In tropical regions, it is more endemic, with periods of 
increased activity occurring more than once a year. 
The public health impact of influenza is dramatic. Estimated rates of influenza-associated 
hospitalization are substantially higher among infants and younger children than among older 
children and are similar to rates for other groups considered at higher risk for influenza-related 
FRPSOLFDWLRQVLQFOXGLQJSHUVRQVDJHG\HDUV'XULQJ–2008, the estimated rate of 
influenza-associated hospitalizations was 91.5 per 100,000 among children aged < 1 year and 
21.9 per 100,000 for children aged 1 through 4 years. Annual hospitalization rates for influenza 
decrease with increasing age, ranging from 240–720 hospitalizations per 100,000 children aged 
< 6 months to approximately 20 hospitalizations per 100,000 children aged 2 through 5 years. 
Hospitalization rates for children aged < 5 years with high-risk medical conditions are higher, 
with estimates of 250–500 hospitalizations per 100,000 children in some studies (1).
In the United States, death associated with laboratory-confirmed influenza virus infection among 
children aged < 18 years has been a nationally reportable condition since 2004. Since reporting 
began, the annual number of influenza-associated pediatric deaths during regular influenza 
seasons has ranged from 34 deaths during the 2011–2012 season to 149 deaths during the 2012–
2013 season (1) (5). However, between 15 April 2009 and 02 October 2010 (the period of the 
2009 H1N1 influenza pandemic), 348 deaths attributed to laboratory-confirmed 2009 H1N1 
influenza occurred among children aged < 18 years, the majority of whom had 1 or more 
underlying medical conditions previously associated with conferring a greater risk for influenza 
complications (1) (5).

Based on current understanding, the epidemiology of influenza B is characterized by major 
epidemics every 2–4 years. It causes infections in all age groups, including children, young adults, 
and the elderly. While influenza affects all age groups, young children remain at increased risk 
for complications and are more likely than the general population to require hospitalization. 
Influenza B has been associated with myalgia, myositis, pneumonia, and leukopenia in  
children (6) (7) (8). Across all ages, the burden of disease from influenza B is less than that from 
A/H3N2 but greater than that from A/H1N1. Overall, it is a significant cause of absenteeism, 
clinic visits, hospitalizations, and deaths (4).
1.1.2
Prevention and Control of Infection 
Currently, the most effective measure for reducing the impact of influenza is to vaccinate persons 
at risk each year before the onset of the influenza season, especially persons at high risk for 
influenza-related complications. The Advisory Committee on Immunization Practices (ACIP) of 
the Centers for Disease Control and Prevention (CDC) recommends that all eligible persons 
6 months of age and older receive annual vaccination against influenza (9).
Influenza vaccine has been effective in reducing influenza-related morbidity and mortality. The 
effectiveness of the influenza vaccine in preventing or attenuating influenza illness depends in 
part on the age and immune competence of the vaccine recipient and on the similarity between the 
virus strains present in the vaccine and those circulating in the community. Most vaccinated 
children and young adults develop high post-vaccination hemagglutination inhibition (HAI)
antibody titers. These antibodies are protective against illness caused by strains similar to those in 
the vaccine or the related variants that may emerge during outbreak periods.  
1.1.3
Advisory Committee on Immunization Practices Recommendations
Because children 6 through 23 months of age are at substantially increased risk for influenza-
related hospitalizations, and children 24 through 59 months of age are at increased risk for 
influenza-related clinic and emergency department visits, ACIP has recommended annual 
vaccination of all eligible children in these age groups. In recent years, ACIP has further 
expanded the targeted age groups, and now recommends that all eligible people 6 months of age 
and older receive annual influenza vaccination (1) (9). The ACIP continues to emphasize the 
LPSRUWDQFHRIYDFFLQDWLQJSHUVRQVPRQWKVRIDJHZKRKDYHKLJK-risk medical conditions (1).
If a child 6 months through 8 years of age is receiving influenza vaccine for the first time, based 
on ACIP recommendations, 2 doses of influenza vaccine should be administered during the 
current season. This recommendation is based on studies demonstrating that vaccine effectiveness 
is lower among children who have never received influenza vaccine previously or who received 
only 1 dose in their first year of vaccination than it is among children who received 2 doses in 
their first year of being vaccinated. Children 6 months through 8 years of age who are adequately 
primed, based on influenza vaccination history, should receive 1 dose during the current season as 
per ACIP recommendations (1) (9).

Background of the Investigational Product
Vaccine Testing and Release
Before being released for clinical use, the 2016–2017 formulation of Fluzone Quadrivalent 
vaccine will have passed all approved release-testing requirements. 
Previous Clinical Experience 
Fluzone vaccine was licensed in the United States in 1947 as a whole-virus preparation and it has 
been available since 1980 as a split-virus preparation. Numerous clinical trials have demonstrated 
its safety, immunogenicity, and effectiveness. Clinical trials, in which Fluzone vaccine was used 
as a comparator, have also demonstrated the safety and immunogenicity of Fluzone Quadrivalent 
vaccine.  Fluzone Quadrivalent vaccine was first licensed in the United States by the Food and 
Drug Administration (FDA) on 07 June 2013 in STN: BL103914/5574 for use in persons 
6 months of age and older.  
1.3
Potential Benefits and Risks
1.3.1
Potential Benefits to Subjects
The benefit to children participating in this trial is the receipt of the 2016–2017 formulation of 
Fluzone Quadrivalent vaccine.
1.3.2
Potential Risks to Subjects
The most frequent side effect of influenza vaccination is pain or tenderness at the injection site 
that usually resolves within 3 days. Injection site reactions are generally mild. 
Systemic findings such as crying, irritability, or fever (young children); malaise or myalgia (older 
children); and other systemic symptoms can occur following vaccination and most often affect 
persons who have had no prior exposure to the vaccine antigens (e.g., young children) (10). These 
reactions usually begin 6 to 12 hours after vaccination and usually resolve within 3 days. A 
previous trial of children 6 to 36 months of age has been published and demonstrates the safety of 
influenza vaccination in this age group (11).
Immediate allergic reactions (e.g., hives, angioedema, allergic asthma, and systemic anaphylaxis) 
occur rarely after influenza vaccination. These reactions probably result from hypersensitivity to 
some vaccine component; the majority is most likely related to residual egg protein (1).
Guillain-Barré syndrome (GBS) is a very rare, acute, and frequently severe polyneuropathy 
characterized by ascending fulminant muscle paralysis. The 1976 swine influenza vaccine 
was associated with an increased frequency of GBS. Among persons who received the swine 
influenza vaccine in 1976, the rate of GBS that exceeded the background rate was 
< 10 cases/1,000,000 persons vaccinated. Evidence for a causal relationship of GBS with 
subsequent vaccines prepared from other influenza viruses is unclear. Obtaining strong 
epidemiologic evidence for such a possible limited increase in risk is difficult for a condition as 
rare as GBS, which has an annual incidence of 10–20 cases per 1,000,000 adults and stretches the 
limits of epidemiologic investigation.

The reasons why swine influenza vaccine triggered GBS in 1976 to 1977 have never been 
discovered. In subsequent annual influenza vaccine programs in the United States, from 1977 to 
1991, the overall relative risk estimates for GBS after influenza vaccination were slightly elevated 
but were not statistically significant in any of the studies. However, in a study of the 1992–1993 
and 1993–1994 seasons, the overall relative risk for GBS was 1.7 (95% confidence interval [CI]:
1.0–2.8; P=0.04) during the 6 weeks after vaccination, representing approximately 1 additional 
case of GBS for each 1,000,000 persons vaccinated. The combined number of GBS cases peaked 
2 weeks after vaccination. A meta-analysis provided a similar risk estimate for GBS following 
receipt of 2009 influenza A (H1N1) monovalent inactivated influenza vaccine (12). Thus, 
investigations to date indicate that there is no substantial increase in GBS associated with 
influenza vaccines (other than the swine influenza vaccine in 1976) and that, if influenza vaccine 
does pose a risk, it is probably slightly more than 1 additional case per 1,000,000 persons 
vaccinated. Even if GBS were a true side effect of vaccination in the years after 1976, the 
estimated risk for GBS (approximately 1 additional case/1,000,000 persons vaccinated) is 
substantially less than the risk for severe influenza, which could be prevented by vaccination in all

influenza vaccination. 
Neurological disorders temporally associated with influenza vaccination such as myelitis 
(including encephalomyelitis and transverse myelitis), optic neuritis/neuropathy, partial facial 
paralysis, and brachial neuritis have been reported. However, no cause and effect has been 
established. Almost all persons affected were adults, and the described clinical reactions began as 
soon as a few hours and as late as 2 weeks after vaccination. Full recovery was almost always 
reported.
In a study of the 2010–2011 influenza season, the CDC found that there was a risk of fever-
associated seizure (convulsion) occurring on the day of influenza vaccination and for 1 day after 
vaccination in children 6 months through 4 years of age. The risk was higher among children who 
received concomitant inactivated influenza vaccine and 13-valent pneumococcal conjugate 
vaccine and peaked at approximately age 16 months. The magnitude of the increased risk was less 
than 1 episode per 1,000 children immunized. A similar risk was found during the 2011–2012 
season (in which the formulation of the influenza vaccine used was the same as that used during 
the 2010–11 season); however, an increased risk for febrile seizures following influenza 
vaccination was not observed during the 2012–13 influenza season. No increased risk was found 
for children older than 4 years of age. After taking into consideration benefits and risks of 
vaccination, no policy change was recommended for use of inactivated influenza vaccine or 
13-valent pneumococcal conjugate vaccine (1).
There may be other risks not yet identified.

Rationale for the Trial
The ACIP recommends that children 6 through 35 months of age receive influenza vaccine with 
7.5 ȝJHA of each influenza viral strain, in a volume of 0.25 mL compared to 15 ȝJ HA per strain 
in a 0.5-mL dose administered to persons 3 years of age and older. This recommendation is based 
primarily on the results of large multicenter trials of monovalent and bivalent whole-virus

influenza vaccines conducted in children during the 1970s (13). These studies demonstrated that 
adverse reactions (ARs) were problematic in children administered whole-virus vaccines and 
downward adjustment of the dose resulted in improved tolerability. However, the introduction of 
split-virus and subvirion influenza vaccines, which are less reactogenic than whole-virus vaccines, 
may have eliminated the necessity for dose adjustments in this young age group.  
The dose administered to young children may impact the level of protection provided by influenza 
vaccines. Clinical studies have shown that vaccine effectiveness may be lower in very young 
children compared with older children. A recent large randomized trial compared rates of
laboratory-confirmed influenza among 4707 children aged 6 through 71 months who received 
inactivated vaccine, MF59-adjuvanted inactivated vaccine, or a non-influenza control vaccine
(14). All study participants received 2 doses 28 days apart: children 6 through 35 months of age 
received 0.25 mL per dose and children 36 through 71 months of age received 0.5 mL per dose. 
During the 2 seasons of this study (2007–2008 and 2008–2009), overall efficacy across all age 
groups of non-adjuvanted inactivated vaccine versus control vaccine against all strains was 43% 
(95% CI: 15%–61%) (14). By age group, efficacy rates were 11% (95% CI: -89%–58%) among 
children 6 through 23 months of age, 40% (95% CI: -6%–66%) among those 6 through 35 months 
of age, and 45% (95% CI: 6%–68%) among those 36 through 71 months of age.  
A 2012 systematic review of published studies estimated vaccine effectiveness among healthy 
children was 40% (95% CI: 6%–61%) for those aged 6 through 23 months and 60% (95% CI:
30%–78%) for those aged 24 through 59 months (15). During the 2010–2011 season, when all 
3 vaccine virus strains appeared antigenically similar to circulating strains, vaccine effectiveness 
was assessed among children in a large multi-site observational study (16). Vaccine effectiveness 
among children aged 6 months through 2 years was 58% (95% CI: 31%–74%) and the 
effectiveness among children aged 3 through 8 years was 69% (95% CI: 56%–77%).
To evaluate whether a higher dose might induce a more robust antibody response (and potentially 
offer improved protection) among children 6 through 35 months of age, investigators have 
evaluated the safety and immunogenicity of a full dose (15 ȝJ HA per strain in 0.5-mL volume)
versus a half dose (7.5 ȝJ HA per strain in 0.25-mL volume). 
Skowronski and colleagues evaluated 252 previously unimmunized children 6 through 23 months
of age who were randomly assigned to receive 2 doses administered 4 to 6 weeks apart of full-
dose (15 ȝJ HA per strain) or half-dose (7.5 ȝJ HA per strain) trivalent inactivated influenza 
vaccine (IIV3) during the 2008–2009 season (17). Children administered full-dose IIV3 
responded with higher geometric mean HAI antibody titers to all 3 vaccine components compared 
to those who received half-dose IIV3. In addition, seroprotection and seroconversion rates were 
higher among children 6 through 11 months of age who received the full-dose vaccine. For 
example, seroprotection rates ranged between 40% and 55% in the half-dose group and between 
70% and 75% in the full-dose group. Rates of fever were not higher among full- versus half-dose 
recipients. Rates of injection site reactions were lower in the half-dose group, but the differences 
between groups were not statistically significant. 
Esposito and colleagues investigated full-dose (15 ȝJ HA per strain) versus half-dose (7.5 ȝJ HA
per strain) virosomal-adjuvanted subunit IIV3 (2008–2009 season) administered 4 weeks apart to 
65 previously unvaccinated children 6 through 35 months of age (18). Following the first dose, 
HAI titers were significantly higher in the full-dose group compared with the half-dose group for

all 3 antigens. No significant differences in HAI titers between groups were noted 4 weeks after 
the second administration, but HAI titers were significantly higher among the full-dose recipients 
6 months post-vaccination for 2 of the strains (H1N1 and H3N2). There was no increase in 
systemic or injection site reactions in the full-dose group versus the half-dose group. A
subsequent Phase III study conducted by these same investigators during the 2010–2011 season 
further supported that a single 0.5-mL dose of the virosomal-adjuvanted subunit influenza vaccine 
could effectively and safely provide long-term immunogenicity to all 3 influenza strains in 
unprimed children 6 through 35 months of age (19).
Langley and colleagues studied 374 children 6 through 35 months of age who were randomly 
assigned 1:1 to receive either a full-dose (15 ȝJ HA per strain) or half-dose (7.5 ȝJ HA per strain) 
of IIV3 during the 2008–2009 season (20). One or 2 doses were administered to primed and 
unprimed children, respectively. Geometric mean HAI antibody titers and seroprotection and 
seroconversion rates were higher among children 6 through 23 months of age who received full-
dose IIV3 versus half-dose IIV3, although the differences were not statistically significant. In 
general, differences of these endpoints between the full- and half-dose groups were greater for the 
younger children 6 through 23 months of age compared to the older cohort 24 through 35 months 
of age. There were no statistically significant differences in reactogenicity between the 2 dose
groups. Fever was not reported more frequently in children who received the full-dose IIV3 
versus those who received the half-dose IIV3. 
Finally, Halasa and colleagues enrolled 243 children 6 through 35 months of age during the 2010–
2011 and 2011–2012 seasons and randomly assigned them 2:1 to receive either full-dose (15 ȝJ
HA per strain) or half-dose (7.5 ȝJ HA per strain) IIV3 (1 or 2 doses depending on vaccination 
history) (13). Among primed subjects, the geometric mean HAI antibody response to H1N1 was 
significantly higher in the full-dose group. A similar higher response to H1N1 in the full-dose 
versus half-dose group was observed among naïve subjects 12 through 35 months of age, although 
the difference was not statistically significant. No immunologic differences between groups were 
noted for the other antigens in the primed or naïve cohorts. No significant differences between the 
full- and half-dose groups were observed for systemic and injection site reactions among the 
primed and naïve cohorts for the 2 seasons combined.  
In summary, vaccine efficacy and effectiveness studies have generally demonstrated that 
inactivated influenza vaccines reduce influenza disease in children, but in some studies the 
effectiveness in children 6 through 35 months of age is lower than that in children 3 years of age 
and older. The practice of administering half-dose IIV (7.5 ȝJ HA per strain; 0.25 mL) to young 
children originates from experience with whole-virus vaccine, which was reactogenic and 
frequently caused fever in young children. Split-virus and subvirion influenza vaccines are less 
reactogenic and data from the studies cited above support the safety of the full-dose IIV (15 ȝJ
HA per strain; 0.5-mL dose) in this population. Further, data from recent studies suggest that in 
children 6 through 35 months of age, full-dose influenza vaccine induces generally higher 
antibody responses compared to those induced by half-dose vaccine, without causing materially
higher rates of systemic or injection site reactions. In most studies, differences in antibody 
responses between the full- and half-dose groups were greatest in the youngest age cohorts 
(i.e., 6- through 11-month-old or 6- through 23-month-old children). 
Full-dose influenza vaccine is now recommended for all children, including those 6 through 
35 months of age, by health authorities in Canada (21), the United Kingdom, and Finland (13). In

2012, when the Canadian National Advisory Committee on Immunization (NACI) first 
recommended a full 0.5-mL dose for children 6 through 35 months of age, it stated (22):
“Infants and toddlers have a high burden of illness and their response to [IIV3] is 
not as robust as with older children. Published and unpublished evidence suggests 
moderate improvement in antibody response in infants, without an increase in 
reactogenicity, with the use of full vaccine doses. In light of this evidence, NACI 
recommends that children 6 to 35 months of age should be given a full dose 
(0.5 mL) of [IIV3] instead of the previously recommended half dose (0.25 mL). 
This recommendation applies whether the child is being given one dose of [IIV3]
or a two dose series.” 
Moreover, although influenza vaccine coverage among young children continues to improve, 
coverage is not yet at desired levels. During the 2013–2014 season, 70.4% of children 6 months 
through 4 years of age received at least 1 dose of an influenza vaccine (23). However, coverage 
rates with 2 doses of influenza vaccine are far lower. During the 2011–2012 season, 59.2% and 
40.5% of children 6 through 23 months and 24 through 59 months of age, respectively, received at 
least 1 dose of influenza vaccine, but only 42.9% and 29.0% of children in the same age cohorts 
were fully vaccinated (24). Similarly, during the 2012–2013 season, 65.9% and 45.9% of children 
6 through 23 months and 24 through 59 months of age, respectively, received at least 1 dose of 
influenza vaccine, but only 45.5% and 31.4% to 33.6% (depending on the definition of unprimed 
children for whom 2 doses were recommended) of children in the same age cohorts were fully 
vaccinated (25). Ferdinands and colleagues recently underscored the importance of being fully 
vaccinated by demonstrating that such children were 74% (95% CI: 19%–91%) or 82% (95% CI: 
23%–96%) less likely to be admitted to a pediatric intensive care unit (PICU) for influenza 
compared to PICU controls or community controls, respectively. In stark contrast, receipt of 
1 dose of vaccine among children for whom 2 doses were recommended was not protective (26).

Based on the foregoing, there is a strong rationale to allow use of the 0.5-mL dose for young
children. Consequently, the purpose of the study described herein is to describe the safety and 
immunogenicity of the 0.5-mL dose (15 ȝJ HA per strain) of Fluzone Quadrivalent vaccine in 
children 6 through 35 months of age, with the intent to modify the vaccine’s Prescribing 
Information (Dosage and Administration) to show the 0.5-mL dose of Fluzone Quadrivalent 
vaccine as indicated for all ages 6 months and older, including children 6 months through 8 years 
of age (who might receive 1 or 2 doses as recommended by the ACIP).

Investigational Plan
5.1
Description of the Overall Trial Design and Plan
5.1.1
Trial Design
This will be a Phase IV, randomized, observer-blinded, 2-arm, multi-center trial to evaluate the 
safety and immunogenicity of 2 different dose levels of Fluzone Quadrivalent vaccine in 
approximately 2190 healthy children 6 to < 36 months of age.
5.1.2
Justification of the Trial Design
See Section 1.4 for the justification for the selection of subjects. The trial will be conducted in a
modified double-blind (i.e., observer-blinded) fashion, with both the Investigators and the subjects
unaware of which vaccine is being administered, to secure objective collection and assessment of 
safety data.
5.1.3
Trial Plan
Using a pre-programmed interactive response technology (IRT) system, subjects will be randomly 
assigned in a 1:1 ratio to either 1 of the following groups:
x
Group 1: 0.25 mL of Fluzone Quadrivalent vaccine (approximately 1095 subjects)
x
Group 2: 0.5 mL of Fluzone Quadrivalent vaccine (approximately 1095 subjects) 
Enrollment will be stratified by age at each site so that approximately 50% of subjects at each site 
will be 6 to < 24 months of age and approximately 50% of subjects at each site will be 24 months 
to < 36 months of age. If necessary to achieve 50% overall enrollment of subjects 6 to < 24 
months of age, individual sites may be permitted to deviate from this ratio. 
All subjects will receive 1 intramuscular dose of Fluzone Quadrivalent vaccine (0.25 mL 
[Group 1] or 0.5 mL [Group 2]) during Visit 1. For subjects for whom 2 doses of influenza 
vaccine are recommended per ACIP guidance, a second dose of Fluzone Quadrivalent vaccine 
(same 0.25-mL or 0.5-mL dose as administered at Visit 1) will be administered during Visit 2 
(28 [window, 28–35] days after Visit 1). 
Blood specimens will be obtained from a planned subset of 1600 subjects randomly selected by an 
IRT system (half in Group 1 and half in Group 2) prior to the first vaccination and 28 (window, 
28–35) days following the final vaccination (Visit 2 for subjects receiving 1 dose; Visit 3 for 
subjects receiving 2 doses) and assayed for immunogenicity.

Solicited AE information will be collected for 7 days after each vaccination. Unsolicited AE 
information and SAE information will be collected from Visit 1 to Visit 2 for subjects receiving 1 
dose or from Visit 1 to Visit 3 for subjects receiving 2 doses. 
Note: Any SAE that occurs after a subject has completed the study but that is likely to be related 
to the product is to also be reported to the Sponsor. 
5.1.4
Visit Procedures
All subjects, Investigators and study site staff, and Sponsor personnel involved in the clinical trial 
will be blinded to the vaccine administered, with the exception of unblinded qualified study staff 
who will administer the vaccine. The unblinded qualified study staff will not participate in the 
collection of safety data.
Medical procedures (injections, examinations, etc.) must be conducted by appropriately licensed 
or credentialed study site staff working within the scope of their licenses/credentials.
Visit 1 (Day 0): Inclusion and Vaccination
The Investigator or delegate will:

Collect influenza vaccination history to determine vaccination schedule (1 dose versus 
2 doses) per ACIP recommendations in effect during the study. 
7)
Perform a directed physical examination, if indicated, based on medical history.
8)
Measure the temperature by the preferred route (i.e., rectal; see Section 9.3.1.3.2) and record 
this information in the source document. If the subject has a WHPSHUDWXUH 100.4°F 
( 38.0oC) defer enrollment until the subject has been afebrile for at least 24 hours (see
Section 5.2.7.1).
9)
If subject meets all inclusion and no exclusion criteria, connect to the IRT system to enter 
required data to receive subject number and vaccine dose identification number, and to 
determine if subject has been assigned to the immunogenicity subset.
10) If subject is randomly assigned to the immunogenicity subset, obtain a pre-vaccination blood 
sample (approximately 5 mL; see Section 7.1 for detailed instructions regarding the collection 
of blood samples).

parents/guardians and should assure appropriate therapy for and follow-up of subjects.
5.2
Enrollment and Retention of Trial Population
5.2.1
Recruitment Procedures
Subjects may be recruited from the general population. The site will ensure that any 
advertisements used to recruit subjects (informational brochures, parent letters, posters, and other 
advertisements) are submitted to Sanofi Pasteur prior to submission to the IRB for approval.
5.2.2
Informed Consent Procedures
Informed consent is the process by which a subject’s parent/guardian voluntarily confirms his or 
her willingness to participate in a particular trial. Informed consent must be obtained before any 
study procedures are performed. The process is documented by means of a written, signed, and 
dated ICF.
In accordance with GCP, prior to signing and dating the consent form, the subject’s parent/guardian
must be informed by appropriate study personnel about all aspects of the trial that are relevant to 
making the decision to participate, and must have sufficient time and opportunity to ask any 
questions.

The actual ICF used at each center may differ, depending on local regulations and IRB 
requirements. However, all versions must contain the standard information found in the sample 
ICF provided by the Sponsor. Any change to the content of the ICF must be approved by the 
Sponsor and the IRB prior to the form being used. 
If new information becomes available that may be relevant to the subject’s parent’s/guardian’s 
willingness to continue participation in the trial, this will be communicated to him/her in a timely 
manner. Such information will be provided via a revised ICF or an addendum to the original ICF. 
Informed consent forms will be provided in duplicate, or a photocopy of the signed consent will 
be made. The original will be kept by the Investigator, and the copy will be kept by the subject’s
parent/guardian.
Documentation of the consent process is to be recorded in the source documents.

5.2.6
Medical History
Prior to enrollment, subjects will be assessed for pre-existing conditions and illnesses, both past 
and ongoing. Any such conditions will be documented in the source document. Significant 
medical history (reported as diagnosis), including conditions for which the subject is or has been 
followed by a physician, or conditions that could resume during the course of the study or lead to 
an SAE or to repetitive outpatient care will be collected in the eCRF. The significant medical 
history section of the eCRF contains a core list of body systems and disorders that could be used 
to prompt comprehensive reporting, as well as space for the reporting of specific conditions and 
illnesses.
For each condition, the data collected will be limited to:
x
Diagnosis (this is preferable to reporting signs and symptomsa)
x
Presence or absence of the condition at enrollment
Dates, medications, and body systems are not to be recorded, and the information collected will not
be coded. Its purpose is to assist in the later interpretation of safety data collected during the trial.
5.2.7
Contraindications for Subsequent Vaccinations
5.2.7.1

Development of any condition that in the opinion of the Investigator would pose a health risk
to the subject or could interfere with the evaluation of the study vaccine (including GBS, 
clinically significant developmental delay, neurologic disorder, seizure disorder, human 
immunodeficiency virus, hepatitis B, or hepatitis C).
x
Development of an immunodeficiency; or receipt of immunosuppressive therapy such as anti-
cancer chemotherapy or radiation therapy; or receipt of long-term systemic corticosteroid 
therapy (prednisone or equivalent for more than 2 consecutive weeks).
x
Adverse events that are considered a contraindication for further participation in the trial.
x
Poor or non-compliance by the subject. In cases where a subject is outside the recommended 
visit schedule, the subject may be continued in the study as a protocol violator and will be 
analyzed accordingly.
Subjects will not be withdrawn due to a definitive contraindication but will be followed up for 
safety and possibly immunogenicity assessment.
5.2.8
Conditions for Withdrawal
Parents/guardians will be informed that they have the right to withdraw their child from the trial at 
any time. A subject may be withdrawn from the study for any of the following:
x
At the discretion of the Investigator or Sponsor due to safety concerns (withdrawal) without 
the parent’s/guardian’s permission
x
At the request of the parent/guardian (dropout)
The following will result in automatic withdrawal or exclusion of a subject from the study:
x
Significant non-compliance with the protocol, based on the Investigator’s judgment
The reason for a withdrawal or dropout should be clearly documented in the source documents 
and on the eCRF. 
The Investigator must determine whether voluntary withdrawal is due to safety concerns (in 
which case, the reason for discontinuation will be noted as “SAE” or “other AE” as appropriate) 
or for another reason.
Withdrawn subjects will not be replaced.
5.2.9
Lost to Follow-up Procedures
In the case of subjects who fail to return for a follow-up examination, documented reasonable 
effort (i.e., documented telephone calls and certified mail) should be undertaken to locate or recall 
them, or at least to determine their health status while fully respecting their rights. These efforts 
should be documented in the eCRF and in the source documents.

5.2.10
Classification of Subjects Who Discontinue the Trial
For any subject who discontinues the trial prior to completion, the most significant reason for 
early termination will be checked in the eCRF. Reasons are listed below from the most significant 
to the least significant (refer to the eCRF completion guidelines for additional details and 
examples):
x
Serious adverse event: To be used when a subject drops out of or is withdrawn from the 
study by the Investigator because of the occurrence of an SAE, as defined in Section 9.3.1.1.
x
Other adverse event: To be used when a subject drops out of or is withdrawn from the study 
by the Investigator because of the occurrence of an AE other than an SAE, as defined in 
Section 9.3.1.1.
x
Non-compliance with protocol: To be used when the Investigator withdraws a subject from 
the study because of failure to follow protocol guidelines, including the case when it is 
retrospectively discovered that a subject did not fulfill the eligibility criteria. The Investigator 
will provide a comment as to the specific cause of non-compliance.
x
Lost to follow-up: To be used when the Investigator withdraws a subject from the study 
because of failure to establish contact, as outlined in Section 5.2.9. The Investigator will provide
documentation that contact was attempted (i.e., return of unsigned certified letter receipt).
x
Voluntary withdrawal not due to an adverse event: To be used when a subject drops out of 
the study for any reason other than those listed above. 
5.2.11
Follow-up of Discontinuations
The site should complete all scheduled safety follow-ups and contact the parent/guardian of any 
subject who has prematurely terminated the trial because of an SAE, other type of AE, non-
compliance with the protocol, or loss of eligibility, including definitive contraindications.
For subjects where the reason for early termination was loss to follow-up or if the subject’s 
parent/guardian withdrew informed consent and specified that they do not want to be contacted 
again and it is documented in the source document, the site will not attempt to obtain further 
safety information. 
For subjects where the reason for early termination is voluntary withdrawal, the site will attempt 
to contact the subject’s parent/guardian except if they specified that they do not want to be 
contacted again and it is documented in the source document. 
5.3
Safety Emergency Call
If, as per the Investigator’s judgment, a subject experiences a medical emergency, the Investigator 
may contact the Sponsor’s RMOs for advice on trial-related medical questions or problems. The 
RMOs will be available 24 hours a day, 7 days a week, as needed. Contact information for the 
RMOs is provided in the Operating Guidelines.

Making an emergency call does not replace the need to report an SAE. The Investigator is still 
required to follow the protocol-defined process for reporting SAEs to the Global 
PharmacoVigilance (GPV) Department (Please refer to Section 10).
5.4
Modification of the Trial and Protocol
Any amendments to this trial plan and protocol must be discussed with and approved by the 
Sponsor. If agreement is reached concerning the need for an amendment, it will be produced in 
writing by the Sponsor, and the amended version of the protocol will replace the earlier version. 
All substantial amendments (e.g., that affect the conduct of the trial or the safety of subjects)
require IRB approval and must also be forwarded to regulatory authorities. 
An administrative amendment to a protocol is one that modifies some administrative or logistical 
aspect of the trial but does not affect its design or objectives or have an impact on the subjects’ 
safety. Regulatory authorities need only be notified about administrative changes. Administrative 
changes do not require IRB approval; however, the IRB(s) must be notified whenever one is 
made.
The Investigator is responsible for ensuring that changes to an approved trial, during the period 
for which IRB approval has already been given, are not initiated without IRB review and 
approval, except to eliminate apparent immediate hazards to subjects.
5.5
Interruption of the Trial
The trial may be discontinued if new data about the investigational product resulting from this or 
any other trials become available; or for administrative reasons; or on advice of the Sponsor, the 
Investigators, and/or the IRB(s). If the trial is prematurely terminated or suspended, the Sponsor 
shall promptly inform the Investigators, the regulatory authorities, and IRB(s) of the reason for 
termination or suspension, as specified by the applicable regulatory requirements.
The Investigator shall promptly inform the trial subjects’ parents/guardians and should assure 
appropriate therapy for and follow-up of subjects.

Identity of the Investigational Product
6.1.1
Identity of Trial Product
The 2016–2017 formulation of Fluzone Quadrivalent vaccine (0.25-mL and 0.5-mL syringe 
presentations) is a sterile suspension prepared from the allantoic fluid of chicken embryos infected 
with specific influenza virus strains. The virus-containing fluid is harvested and the virus 
inactivated with formaldehyde. The influenza virus is concentrated and purified in a linear sucrose 
density gradient solution using a continuous flow centrifuge. The virus is then chemically 
disrupted producing a split antigen. The split antigen is then suspended in sodium phosphate-
buffered isotonic sodium chloride solution. Antibiotics are not used in the manufacture of the 
vaccine. Fluzone Quadrivalent vaccine is essentially clear and slightly opalescent in color.
6.1.1.1
Composition
Each 0.25-mL and 0.5-mL dose of vaccine contains 7.5 μg and 15 μg HA, respectively, of each 
antigen:
x
A/California/07/2009 X-179A (H1N1)  
x
A/Hong Kong/4801/2014 X-263B (H3N2) 
x
B/Brisbane/60/2008 (Victoria lineage; B1)
x
B/Phuket/3073/2013 (Yamagata lineage; B2)
6.1.1.2
Preparation and Administration
Fluzone Quadrivalent vaccine is a liquid preparation; as such, no diluent is required. This product 
is provided in 0.25-mL or 0.5-mL, pre-filled, single-dose syringes. The vaccine will be 
administered intramuscularly into the anterolateral muscle of the thigh or the deltoid muscle, as 
appropriate. The vaccine must be administered within 30 minutes of removing the assigned 
vaccine from the refrigerator.
Prior to administration, all study products must be inspected visually for cracks, broken seals, 
correct label content (see Section 6.3.1), and extraneous particulate matter and/or discoloration, 
whenever solution and container permit. If any of these conditions exists, the vaccine must not be 
administered; another dose is to be used, and the event is to be reported to the Sponsor. 
Subjects must be kept under observation for 20 minutes after each vaccination to ensure their 
safety, and any reactions during this period will be documented in the eCRF. Appropriate medical 
equipment and emergency medications, including epinephrine (1:1000), must be available on site 
in the event of an anaphylactic or other immediate allergic reaction.
6.1.1.3
Dose Selection and Timing
Fluzone Quadrivalent vaccine will be administered as a single 0.25-mL (Group 1) or 0.5-mL 
(Group 2) dose given on Day 0 at Visit 1. For subjects for whom 2 doses are recommended per 
ACIP guidance, a second dose of the same volume as the first dose will be administered at Visit 2 
(28 [window, 28–35] days after Visit 1).

The Investigator will designate unblinded qualified study staff to be responsible for product 
administration.
At the site, products must be kept in a secure place with restricted access. Vaccines will be stored 
in a refrigerator at a temperature ranging from +2°C to +8°C. The vaccines must not be frozen. 
The temperature must be monitored and documented (see the Operating Guidelines) for the entire 
time that the vaccine is at the trial site. In case of accidental freezing or disruption of the cold 
chain, vaccines must not be administered and must be quarantined, and the authorized designee 
should contact the Sanofi Pasteur representative for further instructions.
6.3.2.3
Product Accountability
The Authorized qualified study staff will maintain records of product delivery to the trial site, 
product inventory at the site, the dose(s) given to each subject, and the disposal of or return to the 
Sponsor of unused doses.

The necessary information on the product labels is to be entered into the source document and the 
eCRF. If applicable, information may also be entered into the subject’s vaccination card.
The Sponsor’s monitoring staff will verify the trial site’s product accountability records against 
the record of administered doses in the CRFs and the communication from the IRT system.
In case of any expected or potential shortage of product during the trial, the authorized designee 
should alert the Sanofi Pasteur representative as soon as possible, so that a shipment of extra 
doses can be arranged.
6.3.3
Replacement Doses
If a replacement dose is required (e.g., because the syringe broke or particulate matter was 
observed in the syringe), the site personnel must either contact the IRT system to receive the 
replacement dose allocation or follow the instructions given in the Operating Guidelines.
6.3.4
Disposal of Unused Products
Unused or wasted products will be returned to the Sponsor in accordance with the instructions in 
the Operating Guidelines. Product accountability will be verified throughout the trial period.
6.3.5
Recall of Products
If the Sponsor makes a decision to launch a retrieval procedure, the Investigator(s) will be 
informed of what needs to be done.
6.4
Blinding and Code-breaking Procedures
The study will be performed in an observer-blinded fashion:
x
Unblinded qualified study staff members who are not involved with safety evaluation and 
other trial procedures will prepare and administer the vaccine.
x
Blinded Investigators and study staff who conduct safety assessments will not know which 
vaccine is administered.
x
Subjects will not be informed as to which vaccine will be administered.
The place for storage of the product will be separate from the place where the preparation and 
injection is performed. The Investigator and study staff responsible for safety assessment will not 
be present during vaccination, but will be available in case of an emergency (e.g., anaphylactic 
shock).
The IRT system vendor will be responsible for providing the vaccine dose identification number 
to be received by the enrolled subject. The subject, the Investigator, and study staff members who
collect the safety data and laboratory personnel who analyze the blood samples will all be blinded
to the group assignment. The individual responsible for preparing/administering vaccine will not
be authorized to collect any safety/serology data.

Code-breaking procedures:
The code may be broken by the Investigator only in the event of an SAE and if identification of 
the vaccine received could influence the treatment of the SAE. Code-breaking should be limited, 
to the extent possible, to the subject(s) experiencing the SAE. 
The blind can be broken by the Investigator or a sub-investigator (medical doctor onlya), by 
contacting the IRT system as explained in the code-breaking procedures described in the
Operating Guidelines. Once the emergency has been addressed by the site, the Investigator must
notify 1 of the Sanofi Pasteur RMOs if a subject’s code was broken. All contact attempts with the
Sponsor prior to unblinding are to be documented in the source documents. 
A request for the code to be broken may be made: 
x
by the GPV Department for reporting to health authorities in the case of an SAE, as described 
in the International Conference on Harmonisation (ICH) E2A. In this case, the code will be 
broken only for the subject(s) in question. The information resulting from code-breaking (i.e., 
the subject’s vaccine dose/group assignment) will not be communicated to either the 
Investigator or the immediate team working on the study, except for the GPV representative.  
The IRB must be notified of code-breaking. All documentation pertaining to the event must be 
retained in the site’s study records and in the Sanofi Pasteur files. Any intentional or unintentional 
code-breaking must be reported, documented, and explained, and the name of the person who 
requested it must be provided to the Sponsor. 
6.5
Randomization and Allocation Procedures
The Sponsor or designee will supply a centralized, computer-generated randomization code.
Randomization of subjects will be performed with the permuted block method with stratification
by site, age group, and vaccination schedule. Each subject who meets the inclusion/exclusion 
criteria will be randomly assigned according to his/her age group and vaccination schedule, to 1 
of the 2 groups via an IRT system, according to a 1:1 ratio.
Before vaccination, authorized qualified study staff will contact the IRT system, enter 
identification and security information, and confirm a minimal amount of data in response to IRT 
system prompts. The IRT system will then state the vaccine dose identification number and 
whether the subject will be included in the immunogenicity subset. Subject numbers and vaccine 
dose identification numbers will be recorded on the eCRFs. The full procedures for randomization 
are detailed in the Operating Guidelines. 
If the dose initially allocated for vaccination cannot be used (e.g., because the syringe broke or 
particulate matter was observed), authorized qualified study staff will obtain a replacement dose 
(see Section 6.3.3).

Treatment Compliance
The following measures will ensure that the vaccine doses administered comply with those planned, 
and that any non-compliance is documented so that it can be accounted for in the data analyses:
x
All vaccinations will be administered and recorded by unblinded qualified trial personnel
x
Authorized qualified study staff will maintain accountability records of product delivery to the 
trial site, product inventory at the site, and the disposal of unused or wasted doses
6.7
Concomitant Medications and Other Therapies
At the time of enrollment, ongoing medications, including other therapies (e.g., blood products),
should be recorded in the source document as well as new medications prescribed for new 
medical conditions/AEs during trial participation. 
Documentation in the eCRF of concomitant medication will be limited to specific categories of 
medication of interest beginning on the day of vaccination. This may include medications of 
interest that were started prior to the day of vaccination.
Reportable medications will be collected in the eCRF from the day of vaccination to the end of 
the solicited and unsolicited follow-up period (i.e., between Visit 1 and Visit 2 for subjects 
receiving 1 dose of study vaccine or Visit 1 and Visit 3 for subjects receiving 2 doses of study 
vaccine) as they may impact the response to the vaccination and impact the consistency of the 
information collected on concomitant medications at any vaccination.
The “reportable” medications are classified according to 2 categories. These are:
x
Category 1 antipyretics, analgesics, non-steroidal anti-inflammatory drugs, corticosteroids, 
and other immune modulators. 
Note: inhaled and topical steroids should not be captured.
x
Category 2: Other reportable medications as specified in the protocol (i.e., medications related 
to exclusion criteria) and other medications as noted here. All non-study vaccines, immune 
globulins, and blood or blood-derived products are included in this category. Other 
medications include topical analgesics applied to the site of the blood draw and allergy 
hyposensitization therapy received within 30 days before study vaccination and through the 
Day 28 (window, 28–35 days) visit. These therapies are permissible but nonetheless should be 
recorded as Category 2 medications. Topical analgesics should NOT be applied at the site of 
vaccination; however, if they are applied inadvertently to the vaccination site, they should be 
recorded as a Category 1 medication in this specific instance, not as a Category 2 medication.
The information reported in the eCRF for each reported medication will be limited to:
x
Trade name
x
Given as treatment or as prophylaxis
x
Medication category

inadvertently applied to the vaccination site (see categorization instructions above), will not be 
recorded.
The fact that a medication was given in response to an AE will be captured in the “Action Taken” 
column of the AE only. No details will be recorded in the concomitant medication module of the 
eCRF unless the medication received belongs to 1 of the prelisted categories. Medications will not 
be coded.

Management of Samples
From subjects randomly assigned to the immunogenicity subset, blood samples for the assessment 
of antibody responses will be collected at Visit 1 and at Visit 2 for subjects receiving 1 dose of 
study vaccine, and at Visit 1 and Visit 3 for subjects receiving 2 doses of study vaccine. See the 
Table of Study Procedures and Section 5.1.3 for details of the sampling schedule.
7.1
Sample Collection
From subjects randomly assigned to the immunogenicity subset, at Visit 1 and Visit 2 (or Visit 1 
and Visit 3 for subjects receiving 2 doses of vaccine), approximately 5 mL of blood will be 
collected in tubes provided by or recommended by the Sponsor. Immediately prior to the blood 
draw, the staff member performing the procedure will verify the subject’s identity and will attach 
the pre-printed label that contains that subject’s number and the sampling stage to the tube. It is 
preferred that the blood be taken from the limb opposite to the one that will be used for 
vaccination, but it is not required.
7.2
Sample Preparation
Detailed instructions on how to prepare blood samples for assessment of antibody response are 
contained in the Operating Guidelines provided to the site. An overview of the procedures is 
provided here. 
Following the blood draw, the tubes are to be left undisturbed, positioned vertically and not 
shaken, for a minimum of 1 hour and a maximum of 24 hours to allow the blood to clot. Samples 
can be stored at room temperature for up to 2 hours; beyond 2 hours, they must be refrigerated at 
a temperature of +2°C to +8°C up to a maximum of 24 hours. The samples are then centrifuged, 
and the serum is transferred to the appropriate number of aliquoting tubes. These tubes are pre-
labeled with adhesive labels that identify the study code, the subject’s number, and the sampling 
stage. 
The subject’s number and the date of sampling, the number of aliquots obtained, and the subject’s 
parent’s/guardian’s consent for future use of his/her samples are to be specified on a sample 
identification list. These previous items, as well as the date and time of preparation, are to be

recorded in the source document. Space is provided on the sample identification list to record 
comments regarding the quality of samples. 
7.3
Sample Storage and Shipment
During storage, serum tubes are to be kept in a freezer whose temperature is set and maintained at 
-20°C or below. The temperature will be monitored and documented on the appropriate form 
during the entire trial. If it rises above -10°C for any period of time, the Clinical Logistics 
Coordinator must be notified. See the Operating Guidelines for further details.
Samples will be shipped to Global Clinical Immunology (GCI) at Sanofi Pasteur. The address is 
provided in the Operating Guidelines.  
Shipments to the laboratory (GCI) will be made only after appropriate monitoring and following 
notification of the Clinical Logistics Coordinator. Sera will be shipped frozen, using dry ice to 
maintain them in a frozen state, in the packaging container provided by the carrier. Again, 
temperatures will be monitored. Shipments must be compliant with the International Air 
Transport Association (IATA) 602 regulations. 
7.4
Future Use of Stored Serum Samples for Research
Any unused part of the serum samples will be securely stored at the Sanofi Pasteur serology 
laboratory (GCI) for at least 5 years after the last license approval in the relevant market areas has 
been obtained for the vaccine being tested. 
Subjects’ parents/guardians will be asked to indicate in the ICF whether they will permit the 
future use of any unused stored serum samples for other tests. If they refuse permission, the 
samples will not be used for any testing other than that directly related to this study. If they agree 
to this use, they will not be paid for giving permission. Anonymity of samples will be ensured. 
The aim of any possible future research is unknown today and may not be related to this particular 
study. It may be to improve the knowledge of vaccines or infectious diseases or to improve 
laboratory methods. Human genetic tests will never be performed on these samples without 
individual informed consent.

Clinical Supplies
Sanofi Pasteur will supply the trial sites with protocols, ICFs, eCRFs, diary cards, and other trial 
documents, as well as with the following trial materials: all study vaccines and injection materials, 
blood collection tubes, cryotubes, cryotube storage boxes, cryotube labels, temperature recorders, 
shipping containers, rulers, and digital thermometers.
The means for performing electronic data capture (EDC) will be defined by Sanofi Pasteur. If a 
computer is provided by Sanofi Pasteur, it will be retrieved at the end of the trial.

The Investigator will supply all phlebotomy (except for the blood collection tubes, which are 
provided by the Sponsor) and centrifugation equipment, and biohazard and/or safety supplies. The 
biohazard and safety supplies include needles and syringes, examination gloves, laboratory coats, 
sharps disposal containers, and absorbent countertop paper. The site will ensure that all biohazard 
wastes are autoclaved and disposed of in accordance with local practices. The Investigator will 
also supply appropriate space in a temperature-monitored refrigerator for the storage of the 
products and for the blood samples, and appropriate space in a temperature-monitored freezer for 
serum aliquots.
In the event that additional supplies are required, study staff must contact Sanofi Pasteur,
indicating the quantity required. Contact information is provided in the Operating Guidelines. 
They must allow approximately 1 week for an order to be filled and to have the supplies sent to 
their site.

9.2.2.2
Immunogenicity Assessment Methods
Antibodies to Influenza Viruses
Anti-influenza antibodies will be measured by HAI performed by Sanofi Pasteur’s GCI 
department or an external testing laboratory under GCI’s supervision. Serum samples and quality 
control sera (sheep and/or human sera) will be incubated with Sigma Type III NA to eliminate 
non-specific inhibitors. Adsorption of spontaneous anti-species agglutinins will be performed by 
incubating the serum samples and quality control sera with a red blood cell (RBC) suspension. 
Following this, the mixtures will be centrifuged and the supernatants containing the treated sera 
will be collected for testing. Ten 2-fold dilutions (starting at 1/10) of the treated serum samples 
and quality control sera will be incubated with a previously titrated influenza virus solution at a

to the serum control wells containing only serum and RBCs. The mixture will be incubated and a 
RBC suspension will be added. Following incubation, the results will be read. The endpoint of the 
assay is the highest serum dilution in which complete inhibition of hemagglutination occurred. 
Each serum sample will be titrated in independent duplicates, and the 2 values, which do not 
differ by more than one 2-fold dilution, will be reported. The GMT between the 2 values will be 
calculated after the release of the data to the Clinical Data Management (CDM) platform. The 
lower limit of quantification (LLOQ) for HAI is set at 10, the lowest serum dilution used in the 
assay i.e., 1/10. Titers below this level are reported as < 10.

Safety Definitions
The following definitions are taken from the ICH E2A Guideline for Clinical Safety Data 
Management: Definitions and Standards for Expedited Reporting. 
Adverse Event:
An AE is any untoward medical occurrence in a patient or clinical investigation subject 
administered a pharmaceutical product and which does not necessarily have to have a causal 
relationship with this treatment. An AE can therefore be any unfavorable and unintended sign 
(including an abnormal laboratory finding, for example), symptom or disease temporally 
associated with the use of a medicinal product, whether or not considered related to the medicinal 
product. 
Therefore an AE may be:
x
A new illness
x
The worsening of a concomitant illness
x
An effect of the vaccination, including the comparator
x
A combination of the above
All AEs include serious and non-serious AEs.
Surgical procedures are not AEs; they are the action taken to treat a medical condition. It is the 
condition leading to the action taken that is the AE (if it occurs during the trial period).
Pre-existing medical conditions are not to be reported as AEs. However, if a pre-existing 
condition worsens in frequency or intensity, or if in the assessment of the treating physician there 
is a change in its clinical significance, this change should be reported as an AE (exacerbation). 
This applies equally to recurring episodes of pre-existing conditions (e.g., asthma) if the 
frequency or intensity increases post-vaccination. 
Serious Adverse Event:
Serious and severe are not synonymous. The term severe is often used to describe the intensity of 
a specific event as corresponding to Grade 3. This is not the same as serious which is based on 
patient/event outcome or action criteria usually associated with events that pose a threat to a 
patient’s life or functioning. Seriousness, not severity, serves as a guide for defining regulatory 
reporting obligations.
An SAE is any untoward medical occurrence that at any dose 
x
Results in death
x
Is life-threateninga
a
The term “life-threatening” refers to an event in which the subject was at risk of death at the time of the event; it 
does not refer to an event which hypothetically might have caused death if it were more severe.

x
Requires inpatient hospitalization or prolongation of existing hospitalizationa
x
Results in persistent or significant disability/incapacityb
x
Is a congenital anomaly/birth defect
x
Is an important medical eventc
Additionally, the following important medical events are to be considered as SAEs and reported 
to the Sponsor according to the procedure described in Section 10:
x
New onset of GBS, encephalitis/myelitis (including transverse myelitis), neuritis (including 
Bell’s palsy, optic neuritis, and brachial neuritis), thrombocytopenia, vasculitis, convulsions 
(including febrile convulsions), and anaphylaxis or other hypersensitivity/allergic reactions 
Adverse Reaction:
All noxious and unintended responses to a medicinal product related to any dose should be 
considered ARs.
(The phrase “responses to a medicinal product” means that a causal relationship between a 
medicinal product and an AE is at least a reasonable possibility.)
Unexpected Adverse Reaction:
An unexpected AR is an AR, the nature or severity of which is not consistent with the applicable 
product information (e.g., Investigator’s Brochure for an unapproved investigational medicinal 
product). 
The following additional definitions are used by Sanofi Pasteur:
Solicited Reaction:
A solicited reaction is an event that is prelisted in the eCRF. The assessment of these AEs post-
vaccination is mandatory. A solicited reaction is defined by a combination of:
x
Symptom and
x
Onset post-vaccination
Examples of solicited reactions include injection site pain between Day 0 and Day 7 post-
vaccination, or headache between Day 0 and Day 7. 
a
All medical events leading to hospitalizations will be recorded and reported as SAEs, with the exception of: 
hospitalization planned before inclusion into the study or outpatient treatment with no hospitalization. 
b
“Persistent or significant disability or incapacity” means that there is a substantial disruption of a person’s ability 
to carry out normal life functions.
c
Medical and scientific judgment should be exercised in deciding whether expedited reporting is appropriate in 
other situations, such as important medical events that may not be immediately life-threatening or result in death 
or hospitalization but may jeopardize the health of the subject or may require intervention to prevent one of the 
other outcomes listed in the definition above. These should also usually be considered serious. Examples of such 
events include allergic bronchospasm requiring intensive treatment in an emergency room or at home, blood 
dyscrasias or convulsions that do not result in inpatient hospitalization, the development of drug dependency or 
drug abuse, or new-onset diabetes or autoimmune disease.

A solicited reaction is therefore an AR observed and reported under the conditions (symptom and 
onset) prelisted (i.e., solicited) in the eCRF and considered as related to vaccination.
Unsolicited AE/AR:
An unsolicited AE is an observed AE that does not fulfill the conditions prelisted in the eCRF in 
terms of diagnosis and/or onset post-vaccination. For example, if headache between Day 0 and 
Day 7 is a solicited reaction (i.e., prelisted in the eCRF), then a headache starting on Day 7 is a 
solicited reaction, whereas headache starting on Day 8 post-vaccination is an unsolicited AE.
An unsolicited non-serious AE is an unsolicited AE excluding SAEs.
Injection Site Reaction:
An injection site reactiona is an AR at and around the injection site. Injection site reactions are 
commonly inflammatory reactions. 
Systemic AE:
Systemic AEs are all AEs that are not injection site reactions. They therefore include systemic 
manifestations such as headache, fever, as well as localized or topical manifestations that are not 
associated with the vaccination site (e.g., erythema that is localized but that is not at the injection 
site).
Adverse Events of Special Interest:
AEs of special interest are AEs that are considered by the Sponsor to be relevant for the 
monitoring of the safety profile of the investigational vaccine. 
9.3.1.2
Safety Endpoints
The observational endpoints for the evaluation of safety are:
1)
Occurrence, nature (Medical Dictionary for Regulatory Activities [MedDRA] preferred 
term), duration, intensity, and relationship to vaccination of any unsolicited systemic AEs 
reported in the 20 minutes after each vaccination.
2)
Occurrence, time to onset, number of days of occurrence, intensity, action taken, and whether 
the reaction led to early termination from the study, of solicited injection site reactions 
(prelisted in the subject’s diary card and eCRF) occurring between Day 0 and Day 7 after 
each vaccination.
3)
Occurrence, time to onset, number of days of occurrence, intensity, action taken, and whether 
the reaction led to early termination from the study, of solicited systemic reactions (prelisted 
in the subject’s diary card and eCRF) occurring between Day 0 and Day 7 after each 
vaccination.
4)
Occurrence, nature (MedDRA preferred term), time to onset, duration, intensity, action taken, 
relationship to vaccination (for systemic AEs only), and whether the event led to early

All injection site AEs are considered to be related to vaccination; therefore, all injection site AEs are injection site 
reactions.

termination from the study, of unsolicited AEs between Visit 1 and Visit 2 for subjects 
receiving 1 dose or between Visit 1 and Visit 3 for subjects receiving 2 doses.
5)
Occurrence, nature (MedDRA preferred term), time to onset, seriousness criteria, relationship 
to vaccination, outcome, and whether the SAE led to early termination from the study, of 
SAEs between Visit 1 and Visit 2 for subjects receiving 1 dose or between Visit 1 and Visit 3 
for subjects receiving 2 doses.
Adverse events of special interest will be captured as SAEs. These include new onset of GBS, 
encephalitis/myelitis (including transverse myelitis), neuritis (including Bell’s palsy, optic 
neuritis, and brachial neuritis), thrombocytopenia, vasculitis, convulsions (including febrile 
convulsions), and anaphylaxis or other hypersensitivity/allergic reactions between Visit 1 and 
Visit 2 for subjects receiving 1 dose, or between Visit 1 and Visit 3 for subjects receiving 2 doses. 
9.3.1.3
Safety Assessment Methods
At Visit 2 and Visit 3 (for subjects receiving 2 influenza doses), the Investigator or a delegate will 
ask the parent/guardian about any solicited reactions and unsolicited AEs recorded in the diary 
card, as well as about any other AEs that may have occurred since the previous visit. All relevant 
data will be transcribed into the eCRF according to the instructions provided by the Sponsor.
9.3.1.3.1
Immediate Post-vaccination Surveillance Period
Subjects will be kept under observation for 20 minutes after each vaccination to ensure their 
safety. The post-vaccination surveillance should be documented in the source document. Any AE 
that occurs during this period will be noted on the source document and recorded in the eCRF, as 
follows:
x
Any unsolicited systemic AE occurring during the first 20 minutes post-vaccination will 
be recorded on the eCRF as an immediate unsolicited systemic AE. 
x
Solicited and unsolicited injection site reactions and solicited systemic reactions will be 
recorded and analyzed as starting on the day of vaccination. 
x
Any SAE occurring during the first 20 minutes post-vaccination will be reported in the 
same way as any other SAE and to the Sponsor, according to the procedures described in 
Section 10.
9.3.1.3.2
Reactogenicity (Solicited Reactions From Day 0 to Day 7 After Each
Vaccination)
After each vaccination, the subject’s parent/guardian will be provided with a safety diary card, a 
digital thermometer, and a flexible ruler, and will be instructed how to use them. The following 
items will be recorded by the parent/guardian in the diary card on the day of vaccination and for 
the next 7 days (i.e., Day 0 to Day 7) until resolution:
x
Daily temperature, with the route by which it was taken

Action taken for each event, if any (e.g., medication)
The action taken by the subject’s parent/guardian to treat any solicited reactions will be classified 
in the eCRF using the following scale:
0: None
1: Medication (self-medication with an existing prescription or over-the-counter medication)
2: Health care provider contact (no new medication prescribed)
3: Health care provider contact and prescription of a new medication (health care provider 
instructed subject to take a new medication, either an over-the-counter medication or one 
requiring a written prescription)
4: Hospitalization (inpatient)
Parents/guardians will be contacted by telephone approximately 8 days after each vaccination to 
remind them to record all safety information in the diary card.
If the timing of the telephone call should fall on a weekend or a holiday, the call should be made 
on the next business day. If contact is not made on the designated day, study staff will continue 
calling until contact is made. Every telephone attempt and its outcome will be documented in the 
source document.

Important notes for the accurate assessment of temperature:
Parents/guardians are to measure body temperature once per day, preferably always at the same 
time. The optimal time for measurement is the evening, when body temperature is the highest. 
Temperature is also to be measured at the time of any apparent fever. The observed daily 
temperature and the route of measurement are to be recorded in the diary card, and the highest 
temperature will be recorded by the site in the eCRF. The preferred route for temperature 
measurement in this trial is rectal. In cases where a rectal temperature cannot be obtained, a non-
preferred route (e.g., axillary) may be used. Pre-vaccination temperature is also to be 
systematically collected by the Investigator in the eCRF for all subjects. Tympanic thermometers 
must not be used. 
9.3.1.3.3
Unsolicited Non-serious Adverse Events From Visit 1 to Visit 2 or Visit 3
In addition to recording solicited reactions, the parent/guardian will be instructed to record any 
other medical events that may occur from Visit 1 to Visit 2 (Diary Card 1) for all subjects and 
from Visit 2 to Visit 3 (Diary Card 2) for subjects receiving 2 doses. Space will be provided in the 
diary card for this purpose. For each unsolicited non-serious AE, the following information is to 
be recorded:
x
Start and stop datesa
x
Intensity of the event:
x
For measurable unsolicited non-serious AEs that are part of the list of solicited reactions, 
the size of the AE as well as the temperature for fever will be collected and analyzed 
based on the corresponding scale used for solicited reactions (see Table 9.1 and Table 
9.2)
x
Other unsolicited non-serious AEs will be classified according to the following intensity 
scale:
x
Grade 1: No interference with activity
x
Grade 2: Some interference with activity
x
Grade 3: Significant; prevents daily activity
x
Action taken for each AE, if any (e.g., medication)
The action taken by the parent/guardian to treat any unsolicited AEs will be classified in the 
eCRF using the following scale:

2: Health care provider contact (no new medication prescribed)
a
The stop date of all related AEs will be actively solicited. For other events, the Investigator will provide the stop 
date when it becomes available. Adverse events for which no stop date was obtained during the course of the trial 
will be considered as ongoing at the end of the trial.

Serious Adverse Events
Information on SAEs will be collected and assessed throughout the trial, from Visit 1 until Visit 2 
(or from Visit 1 to Visit 3 for those subjects receiving 2 doses). 
Any SAE occurring at any time during the trial will be reported by the Investigator through the 
EDC system and according to the completion guidelines provided by the Sponsor. All information 
concerning the SAE is to be reported, either as part of the initial reporting or during follow-up
reporting if relevant information became available later (e.g., outcome, medical history, results of 
investigations, copy of hospitalization reports). The Investigator will assess the causal relationship 
between the SAE and the investigational product as either “Not related” or “Related”, as 
described in Section 9.3.1.3.6.
See Section 10 for further details on SAE reporting.
9.3.1.3.5
Adverse Events of Special Interest
Adverse events of special interest will be captured as SAEs. These include new onset of GBS, 
encephalitis/myelitis (including transverse myelitis), neuritis (including Bell’s palsy, optic 
neuritis, and brachial neuritis), thrombocytopenia, vasculitis, convulsions (including febrile 
convulsions), and anaphylaxis or other hypersensitivity/allergic reactions between Visit 1 and 
Visit 2 for subjects receiving 1 dose, or between Visit 1 and Visit 3 for subjects receiving 2 doses. 
9.3.1.3.6
Assessment of Causality 
At each visit, the Investigator or a delegate will perform a directed examination, if indicated, 
based on interim history, and will ask the parent/guardian about any solicited reactions and 
unsolicited AEs recorded in the diary card, as well as about any other AEs that may have occurred 
since the previous visit. All relevant data will be transcribed into the eCRF according to the 
instructions provided by the Sponsor.
The Investigator will assess the causal relationship between each unsolicited systemic AE and 
vaccination as either not related or related, based on the following definitionsa:
0: Not related – The AE is clearly/most probably caused by other etiologies such as subject’s 
underlying condition, therapeutic intervention, or concomitant therapy; or the delay 
between vaccination and the onset of the AE is incompatible with a causal relationship; or 
the AE started before the first vaccination (screening phase, if applicable)

meaning that there is evidence or arguments to suggest a causal relationship
Note: By convention, all injection site AEs (solicited and unsolicited) and all solicited systemic 
reactions are considered to be related to vaccination and referred to as reactions, and therefore do 
not require the Investigator’s opinion on relatedness.
Adverse events likely to be related to the product, whether serious or not, that persist at the end of 
the trial will be followed up by the Investigator until their complete disappearance or the 
stabilization of the subject’s condition (unless the subject’s parent/guardian specified that they do 
not want to be contacted for follow-up and it is documented in the source document). The 
Investigator will inform the Sponsor of the date of final disappearance of the event.
9.3.2
Immunogenicity
The observational immunogenicity objective is presented in Section 2.3.2.
9.3.2.1
Immunogenicity Endpoints
Immunogenicity will be evaluated in a subset of 1600 randomly selected subjects prior to 
vaccination on Day 0 (Visit 1) and at 28 (window, 28–35) days after the final vaccination using 
the HAI technique. For each influenza vaccine strain, HAI assay titers at pre-vaccination (Day 0) 
and at 28 (window, 28–35) days after the final vaccination will be determined in duplicate. 
The derived endpoints are:
x
Geometric means of HAI assay titers for individual subjects at pre-vaccination (Day 0) and at 
28 (window, 28–35) days after the final vaccination.
x
Ratios of individual post-final vaccination titers divided by individual pre-vaccination titers.

Reporting of Serious Adverse Events  
To comply with current regulations on SAE reporting to health authorities, the Investigator must 
document all SAEs regardless of causal relationship, and notify the Sponsor and the Clinical 
Research Associate (CRA) within the notification timelines stated in the following sections. The 
Investigator will give access and provide the Sponsor and the CRA with all necessary information 
to allow the Sponsor to conduct a detailed analysis of the safety of the investigational product(s). 
It is the responsibility of the Investigator to request all necessary documentation (e.g., medical 
records, discharge summary, autopsy) to provide comprehensive safety information. All relevant 
information must then be transcribed into the electronic SAE reporting form (eSAE Form).
10.1
Initial Reporting by the Investigator
Serious adverse events occurring during a subject’s participation in the trial must be reported 
within 24 hours to the Sponsor’s GPV Department and to the CRA. Every SAE must be reported, 
even if the Investigator considers that it is not related to the vaccine. The SAE form must be 
signed by a licensed physician (MD or DO) for whom the task is listed on the Study Task 
Delegation and Signature List after each update to the eSAE Form.
The Investigator must complete the eSAE Form in the EDC application. After validation, an 
e-mail alert will automatically be sent to the GPV mailbox, the CRA, and the RMOs. This 
message will include the country, the study code, the subject number, whether the report is an 
initial report or a follow-up report, the diagnosis and/or symptoms, the seriousness criteria, the 
relationship, if related, and the outcome, if fatal. 
If the EDC system is unavailable, the site must notify the Sponsor using the paper version of the 
SAE Reporting Form, as follows: 
The Investigator must complete the SAE Reporting Form, check off the “Initial Reporting Form” 
box, and send it to the Sponsor by 1 of the following means: 
x
By fax, to the following number:
x
In PDF format to the following e-mail address, using a method of transmission that 
includes password protection:
x
By express mail, to the following address:  
When the system becomes available, the Investigator must transcribe the information from the 
paper version of the eSAE Form into the EDC system.

If there is need for urgent consultation, the Investigator is to contact 1 of the RMOs as described 
in Section 5.3.
10.2
Follow-up Reporting by the Investigator
The eSAE Form completed initially must be updated within 24 hours after the Investigator has 
become aware of any new relevant information concerning the SAE (e.g., outcome, precise 
description of medical history, results of the investigation). After validation, an e-mail alert will 
be sent automatically to the GPV Department and to the CRA. All relevant information must be 
included directly in the eSAE Form. Copies of documents (e.g., medical records, discharge 
summary, autopsy) may be requested by the GPV Department.
The anonymity of the subject must always be respected when forwarding this information.
10.3
Reporting of SAEs Occurring After a Subject Has Completed the Study
Any SAE that occurs after a subject has completed the study but that is likely to be related to the 
product or to the trial must also be reported as soon as possible. In such a case, the reporting 
procedure to be followed is identical to that described in Section 10.1.
10.4
Assessment of Causality
The causal relationship between the SAE and the product will first be evaluated by the 
Investigator, using the following definitions:
0 - Not related: The AE is clearly/most probably caused by other etiologies such as an 
underlying condition, therapeutic intervention, or concomitant therapy; or the delay between 
vaccination and the onset of the SAE is incompatible with a causal relationship; or the SAE 
started before the first vaccination (screening phase, if applicable).
1 - Related: There is a “reasonable possibility” that the SAE was caused by the vaccination, 
meaning that there is evidence or arguments to suggest a causal relationship.
(ICH Guidelines, Clinical Safety Data Management E2A)
Following this, the Sponsor’s Product Safety Officer (PSO) will also assess the causal relationship 
to the product, based on the available information and current medical knowledge.
The decision to modify or discontinue the trial may be made after mutual agreement between the 
Sponsor and the Investigator(s). 
10.5
Reporting SAEs to Health Authorities and IECs/IRBs
The Sponsor will inform the relevant health authorities of any reportable SAEs according to the 
local regulatory requirements. Reporting to the health authorities will be according to the 
Sponsor’s standard operating procedures.

Data Collection and Management
11.1
Data Collection and eCRF Completion
Individual safety diary cards, specifically designed for this trial by the Sponsor and provided to 
the study sites, will be given to study participants for the recording of daily safety information as 
described in Section 9.3.1.3. These diary cards will include prelisted terms and intensity scales 
(see Table 9.1 and Table 9.2) as well as areas for free text to capture additional safety information 
or other relevant details. Parents/guardians will also be provided with rulers for measuring the size 
of injection site reactions, and with standard digital thermometers for measuring daily 
temperatures. To ensure consistency of reporting, the study sites will instruct parents/guardians on 
how to correctly use these tools.
At specified intervals, the Investigator or an authorized designee will interview the 
parents/guardians to collect the information recorded in the diary card, and will attempt to clarify 
anything that is incomplete or unclear. All clinical trial information gathered by the study site will 
be reported electronically by the Investigator or authorized designee using a web-based eCRF. 
(Any information that was not documented in the diary card will first be captured in the source 
document and then reported electronically.) The eCRF has been designed specifically for this trial 
under the responsibility of the Sponsor, using a validated Electronic Records/Electronic 
Signature-compliant platform (21 CFR Part 11).
To ensure the correct and consistent completion of the eCRFs, the Sponsor or authorized 
representative will provide all necessary tools, instructions, and training to all site staff involved 
in data entry prior to study start. Additional instructional documents such as training manuals and 
completion guidelines will be provided to assist with data entry during the course of the trial.
Upon completion of training, each user requiring access to the EDC system will be issued a 
unique username and password. In the event of a change in trial personnel, each newly assigned 
individual will receive a unique username and password; the username and password of a 
previous user may not be reissued. If any trial personnel leave the study, the Investigator is 
responsible for informing the Sponsor immediately so that their access is deactivated. An audit 
trail will be initiated in the EDC system at the time of the first data entry in order to track all 
modifications and to ensure database integrity.
The Investigator is responsible for the timeliness, completeness, and accuracy of the information 
in the eCRFs; must provide explanations for all missing information; and must sign the eCRF 
using an e-signature.

Data Management
Management of Clinical Data
Data generated during the trial will be managed following 2 different processes:
x
Clinical data, defined as all data reported in the eCRF, and laboratory data will be handled 
by the Sponsor’s CDM platform or authorized representative.
x
Data pertaining to SAEs, which are reported by the Investigator on the eSAE Forms or 
SAE Reporting Forms, will be handled by the Sponsor’s GPV Department.
During the trial, clinical data reported in the eCRFs will be integrated into the clinical database 
under the responsibility of the Sanofi Pasteur CDM platform. Data monitoring at the sites and 
quality control in the form of computerized logic and/or consistency checks will be systematically 
applied in order to detect errors or omissions. In addition, data reviews may be performed several 
times by the Sponsor’s staff in the course of the trial. Any questions pertaining to the reported 
clinical data will be submitted to the Investigator for resolution using the EDC system. Each step 
of this process will be monitored through the implementation of individual passwords to maintain 
appropriate database access and to ensure database integrity.
The validation of the immunogenicity data will be performed at the laboratory level following the 
laboratory’s procedures. Information from the laboratory will be checked for consistency before 
integration into the clinical database.
After integration of all corrections in the complete set of data, and after the SAE information 
available from the CDM platform and the GPV Department has been reconciled, the database will be 
released for statistical analysis.
Serious Adverse Event Data Management
During the trial, data pertaining to SAEs reported on eSAE Forms will be integrated into the 
Sponsor’s centralized GPV database.
Upon receipt of an eSAE Form, the data will be entered into the GPV database after a duplicate 
check. Each SAE case will be assigned a case identification number. Each case will be entered in 
the GPV database and assessed by the case management platform or its delegate before being 
reported to the relevant authorities as necessary. Assessment of related cases will be done in 
collaboration with the PSO and the RMO(s). Follow-up information concerning a completed case 
will be entered into the GPV database, and a new version of the case will be created.
The information pertaining to SAEs in the GPV database will be reconciled with that in the 
clinical database.
11.3
Data Review
A review of the data is performed on a regular basis through the data review process led by the 
CDM platform until the database lock.

Statistical Methods and Determination of Sample Size
12.1
Statistical Methods
Summaries of the recruitment and baseline demographic characteristics of the study subjects will 
be presented. The number of subjects enrolled and their age at enrollment (mean, median, and 
minimum and maximum), sex, race, and ethnic origin will be summarized, along with the number 
and description of protocol violations.
Continuous variables will be summarized by descriptive statistics (e.g., means and standard 
deviations for the non-immunogenicity endpoints, and geometric means and their CIs for the 
immunogenicity endpoints); categorical variables will be summarized by frequency distributions 
(frequency counts, percentages, and their CIs for the main endpoints).

2-sided 95% CI of the rate difference between Group 2 (subjects receiving 0.5 mL of vaccine) 
and Group 1 (subjects receiving 0.25 mL of vaccine) is < 5%. The 95% CI of the rate difference

the final vaccination.  Non-inferiority for GMTs will be demonstrated if the lower limit of the 
2-sided 95% CI of the GMT ratio is > 0.667 for each of the 4 virus strains. The 95% CI will be 
calculated using normal approximation of log-transformed titers. The Per-Protocol Analysis 
Set (PPAS) will be used as the primary analysis set for this objective.
x
Seroconversion: The statistical methodology will be based on a 2-sided 95% CI of the 
difference in seroconversion rates (0.5-mL dose minus 0.25-mL dose) at 28 (window, 28–35) 
days after the final vaccination. Non-inferiority for seroconversion will be demonstrated if the 
lower limit of the 2-sided 95% CI is > -10% for the 4 strains. The 95% CI of the rate 
difference will be computed using the Wilson Score method without continuity correction.

Analysis Sets
Three main analysis sets will be used: the Safety Analysis Set, the Full Analysis Set (FAS), and 
the PPAS.
12.2.1
Safety Analysis Set 
The Safety Analysis Set is defined as those subjects who have received study vaccine.a All 
subjects will have their safety analyzed after any dose according to the vaccine they actually 
received at the first dose. Safety data recorded for a vaccine received out of the protocol design 
will be excluded from the analysis (and listed separately).
Safety analysis after each dose will be assessed in the subset of the Safety Analysis Set having 
received that dose. All subjects will have their safety data analyzed after each vaccination 
according to the vaccine they actually received at this dose.  
12.2.2

Ethical and Legal Issues and Investigator/Sponsor Responsibilities
13.1
Ethical Conduct of the Trial/Good Clinical Practice
The conduct of this trial will be consistent with the standards established by the Declaration of 
Helsinki and compliant with the ICH guidelines for GCP as well as with all local and/or national 
regulations and directives.
13.2
Source Data and Source Documents
“Source data” are the data contained in source documents. Source documents are original 
documents or certified copies, and include, but are not limited to, diary cards, medical and 
hospital records, screening logs, informed consent/assent forms, telephone contact logs, and 
worksheets. The purpose of trial source documents is to document the existence of subjects and to 
substantiate the integrity of the trial data collected. Investigators must maintain source documents 
so that they are accurate, complete, legible, and up to date. 
For missing or discrepant data on a diary card, the study coordinator will obtain verbal clarification
from the subject, enter the response into the “Investigator’s comment” page of the diary card, and 
transfer the information to the eCRF.
The subject pre-screening log should list all individuals contacted by the Investigators to 
participate in the trial, regardless of the outcome.
The Investigator must printa any electronic records on an ongoing basis, sign and date them 
immediately after creation, and keep the printouts on file as source documents that can be verified 
by the Sponsor or an inspector against the electronic records. Any later changes of an electronic 
record require the record to be re-printed, dated (with an indication of the date of change), and 
signed. Such records must also be kept together with the original printed copy. 
13.3
Confidentiality of Data and Access to Subject Records
Prior to initiation of the trial, the Investigator will sign a fully executed confidentiality agreement 
with Sanofi Pasteur. 
a  Unless the electronic medical records are managed by validated computerized systems that are compliant with US 
21 CFR Part 11, in which case they are acceptable on their own.

Sanofi Pasteur personnel (or designates), the IRBs, and regulatory agencies, including the FDA, 
require direct access to all study records, and will treat these documents in a confidential manner.
In the event a subject’s medical records are not at the investigational site, it is the responsibility of 
the Investigator to obtain those records if needed.
13.4
Monitoring, Auditing, and Archiving
13.4.1
Monitoring
Before the start of the trial (i.e., before the inclusion of the first subject in the first center), the 
Investigators and the Sponsor’s staff or a representative will meet at the site-initiation visit to 
discuss the trial protocol and the detailed trial procedures. Emphasis will be placed on promoting 
understanding of inclusion and exclusion criteria, visit timing, safety procedures, informed 
consent procedures, SAE reporting procedures, eCRF completion, and the handling of samples 
and products. The Sponsor’s staff or a representative will ensure and document that all material to 
be used during the trial has been received at the site; and that the study investigator team and local 
Sponsor/delegate staff have been properly informed about the trial, GCP and regulatory 
requirements, and the Sponsor’s procedures. Specific training sessions for the study investigator 
team and the CRAs on these topics may be performed as necessary, and should be documented.
The following instruction manuals will be provided: the eCRF Completion Guidelines for 
entering data into the eCRF, and the Operating Guidelines for detailing trial procedures such as 
those related to product management and the handling of samples.
After the start of the trial, the Sponsor’s staff or a representative will be in regular contact with the 
investigational team through telephone calls and regular follow-up visits. The Investigator or 
delegate must be available for these visits and must allow the Sponsor/delegate staff direct access 
to subject medical files and eCRFs. During these visits, the Sponsor/delegate staff will:
x
Evaluate the quality of the trial progress (adherence to protocol and any study-specific 
guidelines, quality of data collection and document completion, presence of appropriate 
signatures on consent forms, occurrence of SAEs, sample and product management, cold-
chain monitoring, archiving)
x
Source-verify completed eCRFs and any corresponding answered queries
x
Determine the number of complete or ongoing issues identified at monitoring visits (e.g., 
protocol deviations, SAEs). Any identified problems will be discussed with the Investigator,
and corrective or preventive actions will be determined, as appropriate.
x
After all protocol procedures have been completed and the data have been entered into the 
eCRF, the Investigator must still be available to answer any queries forwarded by the Sponsor. 
All data-related queries must be completed prior to database lock. 
At the end of the trial, a close-out visit will be performed to ensure that:
x
The center has all the documents necessary for archiving
x
All samples have been shipped to the appropriate laboratory (GCI)
x
All unused materials and products have been either destroyed or returned to the Sponsor

13.4.2
Audits and Inspections
A quality assurance audit may be performed at any time by the Sponsor’s Clinical and Medical 
Quality Operations Department or by independent auditors to verify that the trial has been 
conducted according to the protocol, GCP and ICH requirements, and other applicable 
regulations. An inspection may be conducted by regulatory authorities. The Investigator must 
allow direct access to trial documents during these inspections and audits.
13.4.3
Archiving
The Investigator must keep all trial documents after the completion or discontinuation of the trial,
whatever the nature of the investigational center (private practice, hospital, or institution), for as 
long as required by applicable laws and regulations. In the absence of any applicable laws or 
regulations, trial documents will be kept at a minimum for the duration indicated on the Clinical 
Trial Agreement (CTA). In no event, should study personnel destroy or permit the destruction of 
any trial documents upon less than 90 days advance written notification to the Sponsor. In 
addition, trial documents should continue to be stored, at Sponsor’s sole expense, in the event that 
the Sponsor requests in writing that such storage continues for a period of time that exceeds that 
required by any applicable law or regulation or the CTA. The Investigator will inform Sanofi 
Pasteur of any address change or if they will no longer be able to house the trial documents.
Archived data may be held on electronic records, provided that a back-up exists and that a hard 
copy can be obtained if required. The protocol, documentation, approvals, and all other 
documents related to the trial, including certificates attesting that satisfactory audit and inspection 
procedures have been carried out, will be kept by the Sponsor in the Trial Master File (TMF). 
Data on AEs are included in the TMF. All data and documents will be made available if requested 
by relevant authorities.
13.5
Financial Contract and Insurance Coverage
A CTA will be signed by all the parties involved in the trial’s performance, if relevant. The 
Sponsor has an insurance policy to cover any liabilities that may arise from use of the product 
and/or the study protocol.
13.6
Stipends for Participation
Subjects may be provided with a stipend according to local practice to compensate for the time 
and travel required for study visits and procedures.
13.7
