Can I Donate Blood After Getting a COVID-19 Vaccine?
Yes. But there are some rules you’ll need to follow before you donate your blood after getting the jab. According to the eligibility guidelines set by the FDA, if you qualify to donate blood, in most cases, you can do it any time after you’ve had your COVID-19
vaccine.
But to be eligible, you’ll need to know and be able to give the name of your COVID-19 vaccine’s manufacturer. Approved manufacturers include AstraZeneca, Johnson & Johnson, Moderna, Novavax, and Pfizer. You can donate as long as don't have symptoms of COVID-19 and feel well when you’re about to donate.
If you don’t know which company manufactured your
vaccine, you’ll need to wait 2 weeks before you can donate blood.
