Strange how the study found 2 doses barely effective but 3 were almost as good as natural immunity.

Effectiveness against symptomatic Omicron BA.1 infection was as follows (BNT162b2):

Previous infection without vaccination, 50.2%.

Two-dose vaccination without previous infection, 4.9% (i.e., negligible).

Three-dose vaccination without previous infection, 59.6%.

Two-dose vaccination with previous infection, 51.7%.

Three-dose vaccination with previous infection, 74.4%.

In all 5 groups:

Effectiveness was >90% against severe COVID-19, critical COVID-19, or death (collectively 0.3% of cases) caused by BA.1.
