Because with prior infection and a booster, they found 74.4% protection vs 51.7% with 2 doses and prior infection. against BA.1. It's even better against BA.2.
Quote:
While prior infection provided 50.2% effectiveness against symptomatic BA.1 infection, the primary vaccination of two-dose BNT162b2 vaccination provided negligible protection at -4.9%. Hybrid immunity gained from prior infection and the two-dose vaccination provided protection at effectiveness similar to that of only prior infection at 51.7%.
The effectiveness of a three-dose vaccination regimen was observed at 59.6%, whereas the effectiveness of hybrid immunity of prior infection and a three-dose vaccination was highest at 74.4%.
