What Does 90% Efficacy Mean?

This particular study has looked at the first 94 confirmed cases of COVID-19 out of more than 43,000 volunteers. Each of the volunteers were given either two doses of the vaccine or the placebo.

The US Food and Drug Administration had said that it would expect at least 50% efficacy from any COVID-19 vaccine. Judging by those terms, the Pfizer study results have been overwhelmingly successful.
