>>13638225>Effectiveness against any severe, critical, or fatal disease increased rapidly to 67.7% (95% CI: 59.1-74.7) by the third week after
the first dose, and reached 95.4% (95% CI: 93.4-96.9) in the first five weeks after the second
dose, where it persisted at about this level for six months.
>CONCLUSIONS: BNT162b2-induced protection against infection appears to wane rapidly after its peak right after the second dose, but it persists at a robust level against hospitalization and
death for at least six months following the second dose.
Maintaining >95% efficacy against severe, critical, or fatal infection seems to be in line with other research. A little weird stuff, like the apparent dip between weeks 14-20 It's probably just error but I wouldn't expect it to be obvious. Error after 25 weeks is so fucking big I'm not even sure why they bothered to include it.
