I originally said it looks closer to 30% than 95% based on the limited data we have available, which anyone can do using the data in the article (and can even take a step further verify that these numbers came from the FDA's report). Vaccine Effectiveness (as defined by the CDC [1]) is calculated by: (Risk among unvaccinated group − risk among vaccinated group) / Risk among unvaccinated group Vaccine participants: 18198 Placebo: 18325 Confirmed COVID on vaccine: 8 Confirmed COVID on placebo: 162 Suspected COVID on vaccine (excl. Within 7 days of dose): 1185 Suspected COVID on placebo (excl. Within 7 days of dose): 1407 VE = ( (1569 / 18325) - (1193 / 18198) ) / (1569 / 18325) = 23.43% [1] https://www.cdc.gov/csels/dsepd/ss1978/lesson3/section6.html https://www.cdc.gov/csels/dsepd/ss1978/lesson3/section6.html
