Vaccine records can sometimes be hard to figure out when they use abbreviations or acronyms for common vaccine names.

While some, like DTaP, are usually easy to figure out, others can be confusing.

Will anyone ever get used to using LAIV as a routine abbreviation for a flu vaccine?

Understanding common vaccine abbreviations can help make sure your child's immunizations are up-to-date and that you won't have any problems reading his vaccine records.

A list of common pediatric vaccines that you might see on your child's immunization record could include:

  • DTaP - diphteria, tetanus, and acellular pertussis vaccine

  • DT - pediatric diphteria and tetanus vaccine (for kids too young to get a Td)
  • HepA - hepatitis A vaccine (Havrix and Vaqta)

Other Vaccine Abbreviations

The site where a vaccine is given to a child is often abbreviated.

Common sites can include either a child's:

  • RA (right arm)
  • LA (left arm)
  • RT (right thigh)
  • LT (left thigh)

A vaccine might also be given orally (po) or intranasally (IN).

You will likely see the medical abbreviations IM (intramuscular) and SC (subcutaneous) to indicate other ways that the vaccine might have been administered.
