💡AMAZING BOOSTER DATA—New study shows 3rd shot has 91% efficacy (11x ⬇️lower risk) against #DeltaVariant infection versus 2 shots (>=5 months earlier) among age 60+. Plus, 3rd shot has ~95% efficacy (19.5x ⬇️lower risk) against severe disease!🧵 #COVID19 nejm.org/doi/full/10.10… 
2) moreover. The enhanced booster effects begin being apparent after day 12, increasing higher effects starting even day 10 after the shot perhaps.

3) most were not that elderly either 60-69. I’m also glad to see they enrolled 14% Arab population. The bulk were vaccinated in early February. Thinking of all the people who got vaccines before March that could benefit from this.
4) forgot to mention, Israel study used Pfizer- BioNTech vaccine. Also when analysis restricted to the general Jewish population, the rate ratio was 10.8 for infection & 21.7 lower for severe illness—thus, meaning result similar regardless of mainstream Jewish, Orthodox or Arab.
5) I’m also eager for data on Moderna booster shots, given that 2 doses of Moderna have higher efficacy than 2 doses of Pfizer and much higher than 1 dose of J&J—this is from a major CDC study. I think we need boosters - 3rd shot for elderly, and 2nd shot for J&J ASAP!
