Boosters vs Additional Dose:

  • Booster: a dose of vaccine when the initial sufficient immune response to a primary vaccine series is likely to have waned over time.
  • Additional dose or "third" dose: administration of an additional vaccine dose when the initial immune response following a primary vaccine series is likely to be insufficient. If you are looking for info on additional mRNA doses for immunocompromised individuals, click here.
