Vaccine Efficacy (VE) starts at 96.2% at the seven day to two month point (based on this disclosure and my understanding of surveillance time, it looks like an average of 48 days),
b) falls to 90.1% at the two to four months point (about 95 days on average), and
c) falls to 83.7% at the final/more than four months after the second dose point (about 125 days on average).
Based on a model I built, VE hits zero around ten months after the last shot.
Then we all just need boo$ter $hots weekly. It’s the only way to flatten the curve.
