Claim: Vaccinated children are more likely to have poorer health outcomes compared to unvaccinated children (Brian Hooker, 2023-07-07)
Evidence (2023-09-13): This review will discuss the methodological flaws in the studies and why they don’t provide reliable evidence for the claim that unvaccinated children are healthier than vaccinated children. It will also show that better-designed studies have found no evidence that vaccinated children are more likely to have poorer health outcomes compared to unvaccinated children. Contents - Twice-retracted study by Mawson et al. relied on a survey of homeschooling parents, not representative of the general population - Vaccines don’t weaken children’s immune system - CDC study unable to establish a causal relationship between aluminum levels in vaccines and asthma - Now-retracted study by Lyons-Weiler and Thomas relied on a new, unvalidated metric to suggest vaccinated children are more likely to be sick - Well-designed studies didn’t find an increased risk of poorer health in vaccinated children compared to unvaccinated children - Conclusion - Scientists’ feedback - On other common vaccine-related claims - References [...] Better-designed studies—which were never discussed in the interview—have found no evidence that vaccinated children have poorer health compared to unvaccinated children. The AAP recommends on-time routine immunization of all children and adolescents according to the CDC’s Recommended Child and Adolescent Immunization Schedule.

Claim: Vaccinated children are more likely to have poorer health outcomes compared to unvaccinated children (Brian Hooker, 2023-07-07)
Evidence (2020-05-27): Analysis of health outcomes in vaccinated and unvaccinated children: Developmental delays, asthma, ear infections and gastrointestinal disorders - PMID: 32537156 - PMCID: PMC7268563 - DOI: 10.1177/2050312120925344 Analysis of health outcomes in vaccinated and unvaccinated children: Developmental delays, asthma, ear infections and gastrointestinal disorders [...] Methods: Using data from three medical practices in the United States with children born between November 2005 and June 2015, vaccinated children were compared to unvaccinated children during the first year of life for later incidence of developmental delays, asthma, ear infections and gastrointestinal disorders. All diagnoses utilized International Classification of Diseases-9 and International Classification of Diseases-10 codes through medical chart review. Subjects were a minimum of 3 years of age, stratified based on medical practice, year of birth and gender and compared using a logistic regression model.
Claim: Vaccinated children are more likely to have poorer health outcomes compared to unvaccinated children (Brian Hooker, 2023-07-07)
Evidence (2020-06-01): REDDING, Calif., June 1, 2020 /PRNewswire/ -- A new peer-reviewed study in the journal SAGE Open Medicine detailing the health outcomes of vaccinated versus unvaccinated children concludes that unvaccinated children have better health outcomes than their vaccinated peers within the conditions examined and suggests that further study is necessary to understand the full spectrum of health effects associated with vaccination. [...] The study, coauthored by Dr. Brian Hooker and Mr. Neil Miller, is unique in that all diagnoses were verified using abstracted medical records from each of the participating pediatric practices. Lead author of the study, Dr. Hooker, stated, "The results definitely indicate better health outcomes among the conditions studied in children who did not receive vaccines within their first year of life. These findings are consistent with additional research that has identified vaccination as a risk factor for a variety of adverse health outcomes. Such findings merit additional large-scale study of vaccinated and unvaccinated children in order to provide optimal health as well as protection against infectious diseases." Children's Health Defense (CHD) has assembled nearly 60 studies that find vaccinated cohorts to be far sicker than their unvaccinated peers. CHD is a non-profit organization dedicated to ending the recent epidemic of chronic health conditions affecting 54% of children and recognizes many harmful environmental exposures contributing to an overall decline in children's health.
Claim: Vaccinated children are more likely to have poorer health outcomes compared to unvaccinated children (Brian Hooker, 2023-07-07)
Evidence (2022-09-23): In a small study supported by the National Cancer Institute; the National Heart, Lung, and Blood Institute; the National Institute of Allergy and Infectious Diseases; and the National Institute on Minority Health and Health Disparities, researchers examined children after their COVID-19 vaccinations to learn more about their immune response. [...] All of the vaccinated children made antibodies against SARS-CoV-2. At the same dose as adults, children had a stronger antibody response than adults did. Children who received the adult dose also had a stronger antibody reaction than children who had tested positive for COVID-19 or children with acute MIS-C did. [...] This research helps show how children respond to vaccination and infection with the SARS-CoV-2 virus. The findings suggest that giving children a higher dose of a COVID-19 mRNA vaccine might allow them to recruit more of their immune system to fight an infection.
Claim: Vaccinated children are more likely to have poorer health outcomes compared to unvaccinated children (Brian Hooker, 2023-07-07)
Evidence (2022-01-18): Amid new COVID-19 research indicating serious health risks for unvaccinated children, Sandra Fryhofer, MD, can’t underscore this point enough: vaccination matters. [...] COVID-19 cases and hospitalizations are seven and 11 times higher in unvaccinated adolescents respectively, compared with their vaccinated counterparts. Boosting teens is important but promoting the primary vaccination series is just as crucial, according to Dr. Fryhofer. She is the AMA's liaison to the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices (ACIP) and chair-elect of the AMA Board of Trustees. [...] Compelling findings published in the CDC’s Morbidity and Mortality Weekly Report underscore the health risks associated with unvaccinated children.
Claim: Vaccinated children are more likely to have poorer health outcomes compared to unvaccinated children (Brian Hooker, 2023-07-07)
Evidence (2023-04-20): New data indicates declining confidence in childhood vaccines of up to 44 percentage points in some countries during the COVID-19 pandemic [...] "At the height of the pandemic, scientists rapidly developed vaccines that saved countless lives. But despite this historic achievement, fear and disinformation about all types of vaccines circulated as widely as the virus itself," said Catherine Russell, UNICEF Executive Director. "This data is a worrying warning signal. We cannot allow confidence in routine immunizations to become another victim of the pandemic. Otherwise, the next wave of deaths could be of more children with measles, diphtheria or other preventable diseases." [...] To vaccinate every child, it is vital to strengthen primary health care and provide its mostly female front-line workers with the resources and support they need. The report finds women are at the front line of delivering vaccinations, but they face low pay, informal employment, lack of formal training and career opportunities and threats to their security.

Claim: Vaccinated children are more likely to have poorer health outcomes compared to unvaccinated children (Brian Hooker, 2023-07-07)
Evidence (2024-08-27): Pediatric Flu Deaths Top 100 this Season; Most Unvaccinated [...] - 41 occurred in children younger than 5 years old, who are at higher risk of developing serious flu complications based on their age. [...] Flu vaccination is especially important children who are younger than 5 years of age or children of any age who have certain medical conditions, because they are more likely to develop serious flu complications that can lead to hospitalization and death. Getting vaccinated has been shown to reduce flu illnesses, doctor’s visits, missed school days, and reduce the risk of flu-related hospitalization and death in children. Even if vaccinated children get sick, vaccination has been shown to make illness less severe.
Claim: Vaccinated children are more likely to have poorer health outcomes compared to unvaccinated children (Brian Hooker, 2023-07-07)
Evidence (2024-07-12): - Even though a safe and cost-effective vaccine is available, in 2022, there were an estimated 136 000 measles deaths globally, mostly among unvaccinated or under vaccinated children under the age of 5 years. [...] Any non-immune person (not vaccinated or vaccinated but did not develop immunity) can become infected. Unvaccinated young children and pregnant persons are at highest risk of severe measles complications. [...] Without sustained attention, hard-fought gains can easily be lost. Where children are unvaccinated, outbreaks occur. Based on current trends of measles vaccination coverage and incidence, the WHO Strategic Advisory Group of Experts on Immunization (SAGE) concluded that measles elimination is under threat, as the disease resurged in numerous countries that achieved, or were close to achieving, elimination.
Claim: Vaccinated children are more likely to have poorer health outcomes compared to unvaccinated children (Brian Hooker, 2023-07-07)
Evidence (2024-09-10): COVID-19 usually causes mild symptoms in kids — most commonly, fever and cough. Most children recover in one to two weeks with at-home care. But kids with certain underlying medical conditions face a higher risk of serious illness and hospitalization. Vaccination can protect your child from getting very sick or developing complications from COVID. [...] Children without underlying conditions can also develop severe COVID-19, particularly if they’re unvaccinated. This is why pediatricians urge parents to get their children vaccinated. It’s also important for all members of a household to stay up to date with COVID vaccinations. Doing so can protect infants younger than 6 months (who aren’t eligible for a vaccine) and others who may be more vulnerable to severe illness. [...] Some parents are concerned their teen will develop myocarditis (inflammation of the heart muscle). This is very rare. Viral infections like COVID-19 and the flu cause myocarditis much more often than vaccines do. This is why healthcare providers emphasize that the benefits of vaccination outweigh any possible risks.
Claim: Vaccinated children are more likely to have poorer health outcomes compared to unvaccinated children (Brian Hooker, 2023-07-07)
Evidence (2022-10-07): The Penn State team conducted the largest study to date on the risk of developing myocarditis as a result of having the coronavirus vs. experiencing inflammation following COVID-19 vaccination. The researchers compared patients with COVID-19 — vaccinated and unvaccinated — to those without the virus. They found the risk of myocarditis was 15 times higher in COVID-19 patients, regardless of vaccination status, compared to individuals who did not contract the virus. Next, the researchers separately compared the rates of myocarditis in those who received the vaccines to those in unvaccinated individuals. According to the findings, the rates of myocarditis in people who were vaccinated against COVID-19 were only twofold higher than in unvaccinated people. [...] Investigators conducted a systematic review and meta-analysis of 22 studies published worldwide from December 2019 through May 2022. The studies included nearly 58 million patients who reported cardiac complications and belonged to one of two groups: the 55.5 million who were vaccinated against COVID-19 compared to those who were not vaccinated (vaccination group), and the 2.5 million who contracted the virus compared to those who did not contract the virus (COVID-19 group).
Claim: Vaccinated children are more likely to have poorer health outcomes compared to unvaccinated children (Brian Hooker, 2023-07-07)
Evidence (2005-05-01): Parents of exempt children were more likely than parents of vaccinated children to report low perceived susceptibility to and severity of VPDs, low perceived vaccine efficacy and safety, and a low level of trust in the government. However, parents of vaccinated children also held beliefs that questioned the safety and utility of vaccination: 20.3% were concerned that children get more immunizations than are good for them, 32.2% were concerned that a child’s immune system could be weakened by too many vaccines, and 10.8% reported that it is better to develop immunity from natural disease than from vaccination, although at lower rates than parents of children who were not fully vaccinated. These data are similar to findings by Gellin et al22 for the same questions in the general population and indicate the need for additional educational interventions for parents. The parents of children considering exemptions should be targeted with extra effort to provide them with accurate information from sources that they trust.

Evidence (2022-05-11): Review your family's vaccination records with your provider, especially before your children start day care, school or college and before international travel outside of the U.S. [...] - Being unvaccinated. If you haven't had the measles vaccine, you're much more likely to get measles. [...] People who aren't vaccinated — siblings, for example — should also stay away from the infected person.
Claim: Vaccinated children are more likely to have poorer health outcomes compared to unvaccinated children (Brian Hooker, 2023-07-07)
Evidence (2014-11-07): There are many reasons parents give for delaying a vaccination, from "My baby cries when she gets the shot," to "My child is too young to get so many vaccines." More important than all of these excuses is one simple fact: A child's immune system is more vulnerable without vaccinations. And if it weren't for vaccinations, many children could become seriously ill or even die from diseases such as measles, mumps and whooping cough. See "The Diseases Vaccines Prevent and How" for more information. [...] The threat of death by disease isn't the only medical consequence of skipping vaccinations. An unvaccinated child faces lifelong differences that could potentially put him or her at risk. Every time you call 911, ride in an ambulance, go to the doctor or visit the hospital emergency room, you must alert medical personnel of your child's vaccination status so he or she receives distinctive treatment. Because unvaccinated children can require treatment that is out of the ordinary, medical staff may be less familiar, and less experienced, with the procedures required to appropriately treat your child. [...] People who choose not to vaccinate their children also put others at risk if their child isn't vaccinated and becomes ill. Special groups of people cannot be vaccinated, including those with compromised immune systems (e.g. those with leukemia or other cancers). These people rely on the general public being vaccinated so their risk of exposure is reduced.
Claim: Vaccinated children are more likely to have poorer health outcomes compared to unvaccinated children (Brian Hooker, 2023-07-07)
Evidence (2023-04-20): These are the settings where children like Marwan, Hind and Iman have been immunized for decades. Protected from disease, they’re far more likely to have the opportunity to thrive, the chance to learn and the ability to live healthy lives. [...] The decision to vaccinate a child depends in part on trust. A parent or caregiver must have faith in the health care system, vaccine producers and government health institutions. Even before the COVID-19 pandemic, vaccine hesitancy was identified as one of the top 10 threats to global health. [...] The world is facing a red alert for children’s health: Routine vaccination coverage dropped sharply during the COVID-19 pandemic. UNICEF’s latest report, The State of the World’s Children 2023: For every child, vaccination, explores the reasons behind this red alert and the steps we as a global community must take to make sure that no child is left behind.
Claim: Vaccinated children are more likely to have poorer health outcomes compared to unvaccinated children (Brian Hooker, 2023-07-07)
Evidence (2023-05-07): We did not set out to test a specific hypothesis about the association between vaccination and health. The aim of the study was to determine whether the health outcomes of vaccinated children differed from those of unvaccinated homeschool children, given that vaccines have nonspecific effects on morbidity and mortality in addition to protecting against targeted pathogens [11]. Comparisons were based on mothers’ reports of pregnancy-related factors, birth histories, vaccinations, physician-diagnosed illnesses, medications, and the use of health services. We tested the null hypothesis of no difference in outcomes using chi-square tests, and then used Odds Ratios and 96% Confidence Intervals to determine the strength and significance of the association.
Claim: Vaccinated children are more likely to have poorer health outcomes compared to unvaccinated children (Brian Hooker, 2023-07-07)
Evidence (2020-09-17): A MMWR report on hospitalized children aged 5-11 years with SARS-CoV-2 infections in 14 U.S. states found that during the Omicron wave, unvaccinated children had double the rate of hospitalization compared to vaccinated children. Thirty percent (30%) of hospitalized children had no underlying medical conditions, and children with diabetes and obesity were more likely to develop severe COVID-19. Intensive care unit admission occurred in 19% of hospitalized cases. Increasing COVID-19 vaccination coverage among children aged 5–11 years, especially those at higher risk of severe disease, may help prevent hospitalizations and severe outcomes associated with COVID-19.

Claim: Vaccinated children are more likely to have poorer health outcomes compared to unvaccinated children (Brian Hooker, 2023-07-07)
Evidence (2023-03-26): While vaccination carries some risks, these need to be assessed in light of the benefits of vaccination. The risk of death is greatly increased following a positive test for COVID-19 even in young people, and many studies show that vaccines are highly effective at preventing hospitalisation or death following COVID-19 infection. A positive SARS-CoV-2 test was associated with increased cardiac and all-cause deaths; the risk was higher in those who were unvaccinated at time of testing than in those who were vaccinated. [...] While these rates are adjusted for age, they are not the same as vaccine effectiveness. Vaccinated and unvaccinated people likely differ in characteristics other than age, such as health. Some deaths are expected in vaccinated people as the number who are vaccinated is high and no vaccine is 100% effective. [...] Children aged 5 to 11 years were most likely to be unvaccinated (89.4%) and adults aged 80 years and over (3.6%) were least likely to be unvaccinated. Vaccinations for those aged 5 to 11 years who are not in a clinical risk group are optional, whereas they were recommended for other groups.
Claim: Vaccinated children are more likely to have poorer health outcomes compared to unvaccinated children (Brian Hooker, 2023-07-07)
Evidence (2024-02-05): Cases were identified by registers from the North Thames region of England before and after the MMR vaccine was introduced into the United Kingdom in 1988. Taylor then examined the incidence and age at diagnosis of autism in vaccinated and unvaccinated children. He found that: [...] - No difference in the age of diagnosis of autism was found in vaccinated and unvaccinated children. [...] One of the best studies was performed by Madsen and colleagues in Denmark between 1991 and 1998 and reported in the New England Journal of Medicine. The study included 537,303 children representing 2,129,864 person-years of study. Approximately 82% of children had received the MMR vaccine. The group of children was selected from the Danish Civil Registration System, vaccination status was obtained from the Danish National Board of Health, and children with autism were identified from the Danish Central Register. The risk of autism in the group of vaccinated children was the same as that in unvaccinated children. Furthermore, there was no association between the age at the time of vaccination, the time since vaccination, or the date of vaccination and the development of autism.
