In reply to the discussion: FDA will require a covid-19 vaccine be at least 50 percent more effective than a placebo [View all]Steelrolled
(2,022 posts)20. I think it is more significant in trials for drugs
to improve your quality of life where they are dependent upon surveys for the effectiveness (e.g. rate your joint pain 1-10). In the case of COVID-19, it is more black and white, even though participants might be more inclined to ignore a mild case of COVID-19 "knowing" they have the vaccine.
One thing I wondered about, a common side effect of the vaccine is some soreness around the injection site. I would think that would not occur with the placebo, and thus some people will almost know they have the real thing.

You appeared to be supporting the claim originally made that placebo has zero effect.
