• COVID-19
  • Administering Vaccines

A dose of COVID-19 vaccine was administered subcutaneously instead of by the intramuscular route. Does the dose need to be repeated?

No. CDC does not recommend repeating the dose of any COVID-19 vaccine in circumstances where the dose is administered in an incorrect route or an incorrect site (i.e., not in the deltoid or anterolateral thigh). In the case of a subcutaneous injection, the patient should be advised of the possibility of self-limited local or systemic side effects.
