As reported in the New York Times (and elsewhere):
The company said that the analysis found that the vaccine was more than 90 percent effective in preventing the disease among trial volunteers who had no evidence of prior coronavirus infection. If the results hold up, that level of protection would put it on par with highly effective childhood vaccines for diseases such as measles. No serious safety concerns have been observed, the company said.
This is the best news I’ve heard about the pandemic in quite some time, and it seems legit this time. (I may be biased in favor of Pfizer, though.) We are all hopeful that a safe and effective vaccine will be found, and distributed widely and equitably, as soon as possible.
