Since neither authorized COVID-19 vaccine (shot) contains live virus, there’s no wait time needed before donating blood if you receive the Pfizer or Moderna shot. You will be asked which kind of shot you were given when you go to donate. You should bring the card/handout you received after your shot to your next blood donation. This guidance will change as more kinds of vaccines (shots) become authorized.
