> If a bunch of people get injected with a placebo, it's at worse neutral. If they think they got a functional vaccine and change their behavior as a result, a placebo has the potential to do untold harm all by itself. Further, it erodes loss of confidence so that when a working vaccine is discovered, it's even harder to get people to take it. The FDA has faults, but when you look at people's objections it boils down to erring on the side of being too safe. How much trust would a regulator have if it erred on the side of being too unsafe?
