How soon can I receive my second shot?

The currently authorized vaccines to prevent COVID-19 in the United States require 2 shots to get the most protection:   

  • Pfizer-BioNTech doses should be given 3 weeks (21 days) apart    
  • Moderna doses should be given 1 month (28 days) apart

You should get your second shot as close to the recommended 3-week or 1-month interval as possible. However, there is no maximum interval between the first and second doses for either vaccine. You should not get the second dose earlier than the recommended interval.

Allen Fire Department will not administer your second shot unless it has been at least 21 days (Pfizer) or 28 days (Moderna) since your first dose.
