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

The currently authorized vaccines to prevent COVID-19 in the United States require two shots to get the most protection:

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

You should get your second shot as close to the recommended 21- or 28-day interval as possible. 

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