So did I. Admittedly I only did it once, and in a way that I tried to get them to talk about it and think about it, so I was mostly just talking about the fact that the vax had been gotten in production way too fast to really know if it was safe or not, and that all vaccinations for that type of virus have always been highly unreliable anyway because they mutate too fast, and so on, but since the answer mostly was that they were going to take it anyway I didn't push it. Not my job, as far as I am concerned it is personal duty to find out as much as you can before taking something like that, so if you refuse to even try it's on you. It's not as if all that information was hard to find back then.
