# Standard Vaccine Abbreviations

Centers for Disease Control and Prevention\
Office of the Chief Science Officer\
Immunization Safety Office\
Vaccine Identification Standards Initiative

The Centers for Disease Control and Prevention\'s (CDC\'s) Vaccine
Identification Standards Initiative (VISI) proposed standard
abbreviations for vaccine types. One purpose is to minimize
misinterpretation of a variety of *ad hoc* notations used in medical
records, which may lead to erroneous conclusions as to the actual
vaccine type and brand administered to a patient. Another advantage of
standardized abbreviations is when space limitations on very small
peel-off stickers prevent printing the full generic names of very large
combination vaccines, and the full names of manufacturers or
distributors.

The following nomenclature of abbreviations for past, current, and
future human vaccines are a proposed standard to facilitate accuracy,
consistency, and convenience, and to avoid errors and ambiguity, in
vaccine labeling, medical practice, record keeping, written
communications, and scientific publications.

See the Vaccine Abbreviation Table below for proposed main root
abbreviations for vaccines against most target diseases, as well as some
examples of various optional specifiers to distinguish among different
vaccines for the same disease.

## European Precedents

To facilitate universality, the format builds upon and harmonizes as
feasibly as practical with a [[vaccine abbreviation
nomenclature]{.underline}](http://www.ncbi.nlm.nih.gov/sites/entrez?Db=pubmed&Cmd=ShowDetailView&TermToSearch=10618552&ordinalpos=67&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVDocSum)
(*Vaccine* 2000;18(15):1539--1542) developed by a drafting group
\[PA/PH/OMCL (97) 43, R\] of the European Network of Official Medicines
Control Laboratories of the [[European Directorate for the Quality of
Medicines]{.underline}](http://www.edqm.eu/) of the Council of Europe.
Also adopted are some suggestions by Perry and Parish a half-century
ago, despite different meanings assigned to a few shared homonymous
abbreviations (\"Abbreviated titles for serological products,\" *British
Medical Journal* 1956;2(4983):38--39).

The only unharmonized abbreviations for which the main root differs
between the VISI and European proposals are for vaccines to prevent:

a.  Adenovirus (VISI = **ADE**; Eur = **ADV**)

b.  Cholera (VISI = **CHO~o~** and **CHO~i~**; Eur = **oraCOL** and
    **CHI**, respectively)

c.  *Escherichia coli* disease (VISI = **ECO**; Eur = **ECT**)

d.  Lyme disease/borreliosis (VISI = **LYM**; Eur = **BOR**)

e.  Measles, mumps, and rubella (VISI = **MMR**; Eur = **MEA-MUM-RUB**)

f.  Typhoid (VISI = **TYD**; Eur = **TYP**)

Also, in contrast to VISI, the European proposal has only three
specifiers---lowercase but not subscripted---which *precede* the main
root they modify: \"ora\" (oral), \"a\" (acellular), and \"w\" (whole
cell).

## Principal Main Root Format

In general, VISI abbreviations begin with a main root of three letters
in capital (uppercase) letters for each disease prevented by the vaccine
(e.g., **HAV**, **HBV**, **HIB**, **INF**, **MEA**, **MEN**, **MUM**,
**PNU**, **RAB**, **RUB**, **VAR**, and **YEL**). Different vaccines to
prevent the same disease should share the same main root. For many
purposes, no additional characters are necessary beyond the main root.

## Naming Principles

In deriving a main root abbreviation for a new vaccine, or selecting
from among diverse abbreviations in current use for an existing vaccine,
the choice should try to satisfy as many as possible of the following
characteristics:

-   **Disease/agent representation.** The abbreviation should use the
    first three letters (first choice), or key consonants (second
    choice), or initial letters of multiple words (third choice) of the
    name of the disease or its pathogenic agent.

-   **Intuitiveness.** The abbreviation should represent as intuitively
    as possible to a general audience the name of the disease or its
    pathogenic agent For example, **TUB** for new tuberculosis vaccines
    not containing Bacille Calmette-Guérin, and **ANT** (rather than
    \"AVA\") for anthrax vaccine.

-   **Specificity.** The abbreviation should enhance specificity and
    avoid confusion for other vaccines (obsolete, existing, or
    anticipated) with similar names. If possible, letters should be
    selected from the disease or organism name that distinguish it from
    similarly-named vaccines For example, both rabies vaccine and
    rotavirus vaccine have been abbreviated as \"RV\" or \"Rv\" in the
    literature. To avoid ambiguity, these vaccines are abbreviated
    **RAB** and **ROT** to distinguish them. \"BRU\" is avoided for
    either brucellosis or Brugia malayi vaccines; instead **BRC** and
    **BRG** are used, respectively. In choosing an abbreviation for
    leptospirosis vaccine, **LPT** is selected instead of \"LPS\" to
    avoid confusion with leprosy vaccine (**LPR**), which has no \"T.\"
    **HNT** is used to abbreviate hantaan (hantavirus) vaccine, instead
    of \"HAN,\" to avoid confusion with Hansen\'s disease (leprosy).
    \"MEL\" is avoided for either melanoma or melioidosis vaccines;
    instead **MLN** and **MLD** are used, respectively. \"TYP\" is
    avoided for either typhoid or the typhus vaccines; instead **TYD**,
    **TPL**, **TPM**, and **TPS** are used.

-   **Consistency.** The abbreviation should use a common format for
    current or future vaccines with parallel disease or etiologic agent
    names. For example, among formats in current usage to abbreviate the
    viral hepatitides, such as \"HepX,\" \"Hep X,\" \"HX,\" and \"HXV,\"
    the last is selected (e.g., **HAV** and **HBV**) and should be used
    for future abbreviations **HCV**, **HDV**, **HEV**, and **HGV** for
    hepatitis C, D, E, and G, respectively.

-   **Significance.** The use of the letter \"V\" to represent
    \"vaccine\" or \"virus\" is superfluous and should be avoided to
    maximize for future use the meaning that may be conveyed by only
    three characters in the root abbreviation. \"V\" should be accepted
    only in well-established abbreviations for etiologic agents or
    vaccines, such as for **HAV**, **HBV**, **HIV**, **HSV**, **RSV**,
    and grandfathered alternatives **IPV** and **OPV**.

## Non-Conforming Exceptions

Several long-established, well recognized, and widely accepted
abbreviations which would otherwise not satisfy the format style are
incorporated on a \"grandfather\" basis and indicated by asterisks (\*)
in the table below. The parentheses following these grandfathered
abbreviations illustrate hypothetically what otherwise would have been
the conforming format: BCG (TUB~BCG~), DT (DIP-TET), DTP (DIP-PER-TET),
IG (IMG), QF (QFE), MMR (MEA-MUM-RUB), Td (DIP~r~-TET), and TT (TET). In
the case of polio vaccines, the abbreviations POL~IPV~ and POL~OPV~ are
accompanied by alternatives IPV and OPV, respectively, which may be used
as grandfathered equivalents.

## Specifiers as Subscripts

If necessary or desired to distinguish different vaccines for the same
disease, subscripted specifiers are used after the capitalized main
roots (e.g., **DTP~w~**, **DTP~a~**, **HIB~HbOC~**, **HIB~PRP-T~**,
**PNU~ps~**, **PNU~cn~**, **RAB~HDCV~**, and **RAB~PCEC~**).
Subscripting follows the long tradition of chemical abbreviation, which
is understood everywhere (H~2~O, CO~2~). The case used for the specifier
(lowercase, CAPITAL LETTERS, or Mixed Case) should correspond to the
usual style in current practice for such designations (e.g.,
**LYM~ospA~**, **RAB~FRhL-2~**, **TYD~AKD~**, **TYD~Vi~**). If no style
is established, lowercase is preferred. If a vector also happens to be a
vaccine agent with a root abbreviation of its own, the subscripted
specifier should be the vaccine\'s root abbreviation in capital letters
(e.g., **HIV~rvVEE~**). Multiple specifiers may be used in a single
abbreviation to convey various kinds of information about the vaccine
(see User Flexibility below). The following list shows examples of
specifiers that may be used. \"AAA\" represents the three-letter main
root abbreviation.

-   **AAA~a~**: acellular or attenuated (live)

-   **AAA~ad~**: adsorbed

-   **AAA~atx~**: antitoxin

-   **AAA~av~**: antivenin

-   **AAA~A~, AAA~B~**: A or B, etc., serogroup, serotype, type, etc.

-   **AAA~c~**: central or Central European type or strain

-   **AAA~cl~**: calf lymph

-   **AAA~cn~**: conjugate

-   **AAA~dna~**: deoxyribose nucleic acid

-   **AAA~e~**: Eastern or European type or strain

-   **AAA~i~**: inactivated (killed)

-   **AAA~ig~**: immune globulin

-   **AAA~im~**: intramuscular

-   **AAA~in~**: intranasal

-   **AAA~iv~**: intravenous

-   **AAA~LPS~**: lipopolysaccharide

-   **AAA~mab~**: monoclonal antibody

-   **AAA~(AVP)~, AAA~(GSK)~, AAA~(MRK)~, AAA~(WYE)~**:
    manufacturer/distributor (e.g., Aventis Pasteur, GlaxoSmithKline,
    Merck, Wyeth, etc.)

-   **AAA~n~**: Northern or North American type or strain

-   **AAA~o~**: oral

-   **AAA~ps~**: polysaccharide

-   **AAA~r~**: recombinant or reduced antigen quantity for adults
    (relative to pediatric quantity)

-   **AAA~rna~**: ribose nucleic acid

-   **AAA~rr~**: rhesus reassortant

-   **AAA~s~**: split virion

-   **AAA~tc~**: tissue culture

-   **AAA~txd~**: toxoid

-   **AAA~v~**: vector or vectored vaccine

-   **AAA~w~**: whole cell or whole virion

Rules for specifiers as subscripts:

-   **Dashes.** In general, dashes or hyphens ( - ) should be used to
    separate multiple specifiers conveying distinct kinds of
    information, such as vaccine type and valency (e.g., **PNU~ps~** and
    **PNU~23~** become **PNU~ps-23~**). Dashes should be omitted between
    multiple specifiers for similar or related details about the vaccine
    (e.g., recombinant vector BCG designed to prevent HIV disease:
    **HIV~rvBCG~**, or the protein for a conjugated vaccine:
    **PNU~cnCRM197~**). In any case, dashes within specifiers may be
    added or omitted at the user\'s discretion to improve legibility and
    understanding (e.g., to separate numeric types contained in a
    combination vaccine: **HPV~11-16-18~**).

-   **Legibility.** To improve legibility for reading subscripts in
    typeset publications, it is suggested to follow the common practice
    in notation of other scientific abbreviations (e.g., H~2~O, CO~2~,
    H~2~SO~4~, TCID~50~, Leon 12a~1~b type 3 Sabin poliovirus strain) by
    increasing the size and/or raising the level of subscripts from
    default settings. Specifiers in word processing and typesetting
    software should be modified to maintain their size at 80% to 90% of
    the normal font size, rather than much smaller default sizes. After
    formatting the specifier as a subscript, its size may be increased
    by changing its font size. To avoid potential interference of
    subscripts with uppercase characters on the lines below, the
    subscript position setting may be changed to drop only 15% to 20% or
    less below the baseline, rather than a greater default drop
    percentage.

-   **Alternatives.** If subscripting below the baseline of the main
    root abbreviation is not available, specifiers to distinguish
    different vaccines for the same disease simply may be entered in a
    smaller font size that still retains legibility, i.e., 80% to 90% of
    the size of the three-letter main root; for example, **DTPw**,
    **DTPa**, **HIBHbOC**, **HIBPRP-T**, **MENps-ACYW**, **PNUps-23**,
    **PNUcn-7**, **RABHDCV**, and **RABPCEC** (see column 2 in table
    below). If no text formatting is possible, as in ASCII text and
    database entry, type the specifiers without size or position
    adjustment; for example, **DTPw**, **DTPa**, **HIBHbOC**,
    **HIBPRP-T**, **MENps-ACYW**, **PNUps-23**, **PNUcn-7**,
    **RABHDCV**, and **RABPCEC** (see column 3 in table below).

-   **Data entry screen display.** Data entry software programs may be
    designed to display all characters after the third in the preferred
    subscripted and/or reduced-size format, and to format thus any
    printed output. In such programs, keyboard entry of grandfathered
    two-letter main root abbreviations might be preceded by a space
    character to avoid misregistration (inadvertently as third position)
    of the initial character of the specifier (should be fourth
    position); for example, ¯**DT(AVP)**, ¯**IG(BAY)**, ¯**QF(CSL)**,
    ¯**Td(SSV)**, ¯**TT(SII)**, and ¯**YF(AVP)**.

-   **Omitting subscript specifiers.** Various possible subscript (or
    lowercase) specifiers may be omitted when there is no ambiguity as
    to the vaccine which the root abbreviation identifies, such as
    **HIB** to indicate **HIB~cn~** when its forerunner **HIB~ps~**
    vaccine is no longer in use. The same principle would apply to the
    use of only the capitalized root abbreviations for **PNU~cn~** and
    **MEN~cn~** in possible future combination vaccines (such as
    **MEN-PNU** or **HIB-PNU**) when it is anticipated only conjugated
    antigens would be used in such products. Similarly, **PNU~5~**,
    **PNU~7~**, **PNU~9~**, and **PNU~11~** may be used to indicate 5-,
    7-, 9-, and 11-valent pneumococcal conjugate vaccines, respectively
    (instead of **PNU~cn-7~**, for example), when there is no contextual
    ambiguity with existing (**PNU~ps-23~**) or future polysaccharide
    vaccines (**PNU~ps~**) which do not have these valencies. Again,
    combination products containing inactivated poliovirus vaccine
    **POL~IPV~** may eliminate the specifier when there is no ambiguity
    with the oral polio vaccine, as in **HIB-PNU-POL** and
    **DTPa-HBV-POL**.

## Vectored Vaccines

Vaccines to prevent a disease (e.g., human immunodeficiency virus
disease, influenza, listeriosis, or smallpox) which consist of
recombinant or attenuated agents for other diseases acting as vectors or
Jennerian vaccines (e.g., recombinant BCG, recombinant Listeria
monocytogenes, recombinant Salmonella typhimurium, or vaccinia virus,
respectively) should be assigned the root abbreviation for the disease
to be prevented (e.g., **HIV**, **INF**, **LIS**, and **SMA**,
respectively). Specifiers (see below) may be appended to identify the
vector or Jennerian agent used (e.g., **HIV~rvBCG~**, **INF~rvLIS~**,
**LIS~rvSAL~**, and **SMA~vac~**, respectively).

## Boldfacing Recommended

Vaccine abbreviations should be **boldfaced** to enhance recognition as
a vaccine abbreviation, and to distinguish them from abbreviations for
etiologic agents and disease, unless contravened by the style guidelines
of the publication.

## Distinguishing Vaccine from Agent or Disease

There are occasions when documents will need to distinguish between
etiologic agents or disease names and the vaccines which prevent them.
By design, abbreviations for vaccines are often the same as
abbreviations for the associated etiologic agent (such as hepatitis B
virus, *Haemophilus influenzae* type b, human immunodeficiency virus,
and herpes simplex virus) or disease (such as group A and group B
streptococcal diseases and respiratory syncytial virus).

In such cases, we suggest that the first mention of a vaccine in the
main text is followed immediately by its boldfaced abbreviation in
parentheses (for example, \"hepatitis B vaccine (**HIB**),\"
\"*Haemophilus influenzae* type b vaccine (**HBV**),\" \"human
immunodeficiency virus vaccine (**HIV**),\" or \"group B streptococcal
disease vaccine (**GBS**)\"), and that the vaccine abbreviation be
boldfaced thereafter in the document.

At the first naming of an etiologic agent or disease in the document, a
non-boldfaced abbreviation may be provided in parentheses (for example,
\"hepatitis B virus (HBV),\" \"*Haemophilus influenzae* type b (Hib),\"
\"human immunodeficiency virus (HIV),\" or \"group B streptococcal
disease (GBS)\"), or an alternative designation established and used
thereafter, such as \"HB virus,\" \"Hib disease,\" \"HIV virus,\" or
\"GBS disease.\"

## Combination Vaccine Notation

For combination vaccines with antigens preventing two or more diseases,
hyphens or dashes ( - ) without spaces are used to link the
abbreviations of its separate components (for example,
**DTP~w~-HIB-HBV**, **DTP~a~-HBV-POL**, **HAV-HBV**, **HIB-HBV**,
**MEA-RUB**, **MMR-VAR**, and **MUM-RUB**). This differs from the
European proposal, which uses spaces to separate the multiple antigens
comprising an individual combination vaccine.

## Listing Sequence of Combination Antigens

The individual vaccine antigens comprising a combination vaccine should
be ordered in an abbreviation according to the following rules, arranged
in descending order of precedence:

-   **Grandfathered combinations.** For existing combination vaccines
    whose abbreviations have been incorporated unchanged into these
    guidelines based on widespread use and acceptance, such as **DTP**,
    **DTP~w~**, and **DTP~a~**, the non-alphabetical sequence in which
    antigens may be arranged remains unchanged.

-   **New additions to existing combinations.** When a new antigen is
    added to a previously-licensed combination of antigens, the
    abbreviation root for the new antigen should be appended *after* the
    previously combined antigens (for example, **DTP~w~-HIB**,
    **DTP~a~-HIB**, **DTP~a~-HIB-POL**, and **MMR-VAR**) even if the new
    antigen appears out of alphabetical order.

-   **Multiple newly-added antigens.** When multiple new antigens are
    added simultaneously to an existing combination, the new antigens
    should be listed in alphabetical order according to the official,
    spelled-out, full generic name of the vaccines being combined (for
    example, **DTP~a~-HIB-HBV**, **DTP~a~-HIB-HBV-POL**). Some
    abbreviations listed in the table below for future combination
    vaccines may need to be re-ordered according to the actual
    chronology in which their components become combined, according to
    the prior rule.

-   **New combinations.** When a new combination vaccine is developed
    from multiple antigens not previously together in a licensed
    product, the abbreviation roots should be listed in alphabetical
    order according to the official, spelled-out, full generic names of
    the component vaccines (for example, **HAV-HBV**, **HIB-HBV**,
    **HIB-MEN**, **HIB-MEN-PNU**, and **MEN-PNU**).

## Simultaneous Vaccination Notation

As a convention to indicate the administration of separate vaccines to
the same patient on the same day, in distinct sequential parenteral
injections or oral/mucosal dosings (often described as \"simultaneous
vaccination\"), the plus symbol surrounded by spaces ( + ) should
separate abbreviations of the multiple vaccines administered. For
example, \"At a clinic visit at 2 months of age, the patient received
**DTP~w~-HIB** + **HBV** + **OPV** + **ROT**.\" Or, \"In this study, one
group received **DTP~a~-HBV-POL** + **HIB** + **HAV** + **INF~a~**,
while another received **DTP~a~-HIB** + **HAV-HBV** + **POL~IPV~** +
**INF~a~**.\"

## Ambiguous and Illegible Conjunctions

We strongly discourage the use of reverse ( \\ ), vertical ( \| ), or
forward ( / ) slashes to link the separate component antigens of a
combination vaccine, denote simultaneous vaccination, or distinguish the
lyophilized component from the liquid component(s) of a combination
vaccine. Such conjunctions are ambiguous in meaning and provide poor
visual resolution. Compare the visual distance at which the components
of these two notations can be discerned: **DTP~a~-HIB-HBV-POL** and
**DTP~a~/HIB/HBV/POL**.

## User Flexibility

Users may face circumstances in which more or less specificity is needed
for an abbreviation. In such cases, one or more subscripts may be added
to or removed from a listed abbreviation. Additional dashes or hyphens
may be added to separate multiple specifers at the user\'s discretion,
according to guidelines for specifier dashes above. The intended meaning
of such a modified abbreviation should be spelled out at first use of
the abbreviation or explained elsewhere in the document. Examples
follow.

-   **Conjugate used.** To identify a vaccine by the protein with which
    it is conjugated, the **PNU~cn~** abbreviation, for example, could
    be appended, as in **PNU~cn-T~**, **PNU~cn-D~**, **PNU~cn-OMPC~**,
    and **PNU~cn-CRM197~** or just **PNU~cn-CRM\ ~**.

-   **Serotypes and seed strains.** To identify the specific serotypes
    in a vaccine, their letter or number designations can be added to
    the abbreviation. For example, the **MEN~ps~** and **MEN~cn~**
    abbreviations could become **MEN~ps-ACYW~**, **MEN~cn-AC~**, and
    **MEN~cn-B~**. The live attenuated cholera vaccine comprised of
    recombinant vector *Salmonella typhi* Ty21a strain from the Center
    for Vaccine Development (CVD103-HgR) could be abbreviated as
    **CHO~arvCVD103-HgR~**. **OPV~1~** and **OPV~2~** could designate
    the monovalent oral polio vaccines studied and used in the late
    1950s and early 1960s for vaccines of type 1 and type 2,
    respectively. However, \"**OPV~3~**\" is ambiguous: it could be
    interpreted as a redundant abbreviation for **OPV**---the current
    trivalent oral polio vaccine---or as a representation of the former
    monovalent type 3 vaccine. Thus, **OPV~3~** should be accompanied at
    its first use in a document by an explanation of its intended
    meaning.

-   **Valency.** To identify a vaccine by its number of serotypes,
    serogroups, or component antigens, the quantity can be added to the
    subscript, as in **PNU~ps-23~**, **PNU~cn-7~**, **PNU~cn-11~**,
    **DTP~a-1~**, **DTP~a-2~**, **DTP~a-3~**, and **DTP~a-4~** (the last
    four **DTP~a~** vaccines use numbers to indicate the number of
    acellular antigens of pertussis toxin, pertactin, filamentous
    hemagglutinin, and/or fimbriae included in each vaccine).

-   **Manufacturer.** To identify a vaccine by its producer or
    distributor, the manufacturer\'s abbreviation can be added as a
    subscript within parentheses, e.g., **ANT~(BPT)~**, **DTP~a(WYE)~**,
    **DTP~a(NAV)~**, **DTP~a(AVP)~**, **HBV~(GSK)~**, **HBV~(MRK)~**,
    **INF~(AVIR)~**, **INF~(AVP)~**, **INF~(MDV)~**, **INF~(PDL)~**,
    **INF~(WYE)~**, **PNU~cn(AVP)~**, **PNU~cn(MRK)~**,
    **PNU~cn(WYE)~**, **PNU~ps(MRK)~**, **PNU~ps(WYE)~**,
    **RAB~(CHIR)~**, **RAB~(AVP)~**,**SMA~vac(WYE)~**, and
    **TBE~w(BAX)~**. No hyphen is needed when appending such a
    parenthesis to an existing subscript.

## Order of Multiple Subscripts

When specifiers are joined in an abbreviation\'s subscript, they should
be listed in the following order, although intervening ones may be
omitted.

1.  **Major subcategory.** First, the specifier for a major subcategory
    of vaccine type, such as polysaccharide versus conjugate, acellular
    versus whole-cell antigens, or inactivated versus live attenuated.
    For example, **PNU~cn~**, **DTP~a~**, and **INF~a~**.

2.  **Key component.** Second, the specifier for a key component
    contained in a vaccine, such as the protein conjugate. For example,
    **PNU~cn-CRM~** or **PNU~cn-OMPC~**.

3.  **Valency.** Third, the specifier for valency to indicate the number
    of separate serotypes or antigens. For example, **PNU~cn-CRM7~** or
    **PNU~cn-CRM-7~**, **PNU~cn-OMPC7~** or **PNU~cn-OMPC-7~**,
    **PNU~cn-T11~** or **PNU~cn-T-11~**, **DTP~a-1~**, **DTP~a-2~**,
    **DTP~a-3~**, **DTP~a-4~**, or **INF~a-3~**.

4.  **Manufacturer.** Fourth, the specifier to indicate the
    manufacturer. For example, **PNU~cn-CRM7(WYE)~**,
    **PNU~cn-OMPC7(MRK)~**, **PNU~cn-T11(AVP)~**, **DTP~a-1(NAV)~**,
    **DTP~a-2(AVP)~**, **DTP~a-3(SBB)~**, **DTP~a-4(WYE)~**, or
    **INF~a-3(AVIR)~**.

## Vaccine Abbreviation Table

The following table lists the proposed main root abbreviations for
vaccines against most target diseases, as well as some examples of
various optional specifiers to distinguish among different vaccines for
the same disease. The more complex specifiers might be used in technical
scientific publications, while simpler specifiers, if any, may suffice
for general record-keeping in medical charts.

The first column shows the preferred vaccine abbreviation, which uses
subscripted specifiers. Columns 2 and 3 illustrate alternatives when
subscripting is not available, by reducing the font size of the
specifier in the second column, and by using plain text when no
formatting is possible in the third column. The final column provides
the full vaccine name. Entries are listed alphabetically by the
abbreviation.
