Can I drink alcohol after my COVID vaccine?

But... everything in moderation, as they say. Drinking too much alcohol (more than 3 units of alcohol a day) can put pressure on your immune system and therefore reduce your body’s ability to mount an immune response.

In addition, heavy drinking can also worsen vaccine-related side effects.

So see how you feel, perhaps give alcohol a miss for a couple of days afterwards, and binge drinking should certainly be avoided. This allows you to get the most out of the vaccine or booster.
