Pfizer update: final analysis confirms 95% efficacy, ready to seek emergency approval "within days"

https://www.cnn.com/2020/11/18/health/pfizer-coronavirus-vaccine-safety/index.html
"Final analysis of the Phase 3 trial of Pfizer's coronavirus vaccine shows it was 95% effective in preventing infections, even in older adults, and caused no serious safety concerns, the company said Wednesday.

The company counted 170 cases of coronavirus infection among volunteers who took part in the trial. It said 162 infections were in people who got placebo, or plain saline shots, while eight cases were in participants who got the actual vaccine. That works out to an efficacy of 95%, Pfizer said.

The data show Pfizer's initial claim of a better than 90% efficacy -- a claim that stunned and pleased health officials and vaccine developers last week -- holds up.

"Efficacy was consistent across age, race and ethnicity demographics. The observed efficacy in adults over 65 years of age was over 94%," Pfizer and its German partner BioNTech said in a joint statement.

number of subjects for analysis and can be more exact in the percentage. I think both Pfizer and Moderna will have plenty of "customers" and more demand for their respective vaccines than either could handle for the foreseeable future. It was really good news that Pfizer's vaccine seems equally effective across demographics including age (i.e., over age 65). Maybe the same is true for the Moderna vax, but I didn't see it reported. I think all of this is wonderful news and I would gladly accept innoculation with either vaccine as soon as it is available (barring any breaking bad news, of course).
