Question

Is the Pfizer booster shot effective against the Omicron variant?.

Answer 1

Not really, I mean it still helps you more then not having any vaccine. The shots were created for the first strand so were way more effective for the first strand. You are more likely to get sicker if you get the Omicron strand then the first one I guess. But it can still help yes.

Answer 2

Yes, the Pfizer booster shot effective against the Omicron variant
