How do we know the vaccine works?

posted on 2021-12-17

In the past few months, and especially in the last weeks, I have been doing some pretty intensive research on the safety and efficacy of the Covid vaccines. I was getting a lot of questions on it from some of my friends, and I wanted to be able to give them my perspective on this as a biologist looking at the scientific literature. I've been working on a longer document looking at all sorts of issues that people bring up, but for starters I‘d like to give a quick overview of some of the studies that look at the vaccines’ efficacy. In other words: how do we know these vaccines actually work?
