How many shots of COVID-19 vaccine will be needed?

Two of the currently authorized vaccines to prevent COVID-19 (Pfizer and Moderna) require two shots to get the most protection, while the third vaccine (Janssen) requires one.:

  • Pfizer-BioNTech doses should be given three weeks (21 days) apart
  • Moderna doses should be given one month (28 days) apart
  • Janssen is one dose

If you are receiving the Pfizer or Moderna vaccine, you should get your second shot as close to the recommended three-week or one-month interval as possible. 

Additional COVID-19 vaccines are in Phase 3 clinical trials.
