I'll replicate the tweet, since I think it's useful when discussing these matters: > It doesn't stop infection. Or transmission. Don't think of it as a vaccine. Think of it - at best - as a therapeutic with a limited window of efficacy and terrible side effect profile that must be dosed IN ADVANCE OF ILLNESS. And we want to mandate it? Insanity, "Don't think of it as a vaccine" is trivially false, as it is literally a vaccine. "terrible side effect profile" is false: we now have data that shows at population-scale the vaccine was overwhelmingly effective with minimal side-effects. (We knew that before then, too; anyone looking at the efficacy rates knew it before it hit the gen pop.) "that must be dosed IN ADVANCE OF ILLNESS": that's how nearly all vaccines work, yes. Your body can't really fight an infection with the effects of the vaccine that it hasn't had the time to produce the corresponding antibodies for. (AIUI, rabies is the exception to this, where you can be vaccinated after infection, but that's due to rabies being a very slow moving infection.) "It doesn't stop infection. Or transmission." And the rest of the tweet is just misleading: nothing is guaranteed in life, but we can look at the probabilities and risks associated with and without the vaccine and know which choice has a lower risk profile, and make a sane recommendation based on that. Wearing your seat belt can't stop death in a car accident, but it is still a good idea. Tweets like these very likely drove people to not get vaccinated, leading to either them dying, or them passing it on to someone who did. Using some small technicalities around things that cannot be guaranteed not being guaranteed to try to push a bad policy and decision making is not "correct". The evaluation of risk here in the tweet is absurdly bad. Whether Twitter should be forced to promulgate such idiocy is a conversation that's been had many times since on HN, but it is idiocy.
