The type of vaccine available depends on the clinic, and individuals must receive an age-appropriate COVID-19 vaccine. The Indiana COVID-19 Vaccine Map shows the type(s) of vaccine available at a clinic. The vaccine type is also shown on the registration site.  For primary and booster vaccination, people should receive an age-appropriate mRNA vaccine (Pfizer or Moderna). The Johnson & Johnson vaccine is authorized for anyone age 18 and older if no other approved vaccine is available.
