Pfizer says their vaccine is 90% effective. Does that means 10% people get infected? We currently have a 3% infecting rate nationwide. Meanwhile the stock price will shoot up dramatically. GOP is claiming the announcement coming after the election was held back to help Biden. The market will soar today but until the public is widely vaccinated that won't translate into better economic numbers.
I hope it means the incidence of COVID-19 in the vaccinated test group was reduced by 90% compared to the unvaccinated(actually placebo receiving) group. They said that 94 people got the virus of the 44,000 some odd study subjects.
So of the 94 virus cases seen, ~80 were unvaccinated against ~8 that got the vaccine but then got sick anyway? That's a pretty good efficacy rate.
Assuming it's true, I hope it holds against the mutation rate of the virus.
And they are apparently collecting two months of safety data on around half of the study's roughly 44,000 participants -- expected in late November.
Better numbers sooner than I would have expected -- here's hoping.
