> I'm getting my 2nd shot this week, but both mRNA and modified adenovirus vaccines have never been used for mass vaccinations before. The history of medicine is litered with interventions that were seen as totally safe and wonderful and lead to terrible consequences after some time. Push towards massive adoption of an intervention sets off my alarm bells. These events sadly happen and there will always be unknown unknowns, not only, but also because of human hubris. However, it seems you are overestimating the prevalence of such events and extrapolating that to the current situation. If you take a birds-eye view on medical progress over the last 50-100 years says, it's just incredible. > All that said, personally, it seems the unknown long term risks of vaccination outweigh the more or less known risks of covid both on an individual level (I don't want to get it) and a community level (I'd rather like community spread to stop, so I can go back to being a hermit by choice); but if community spread wasn't happening near me, I would be happier not trying new medicine within a year of development. Agree with you. From what we know today it seems that the unknown long term risks of the vaccines are a subset of the unknown long term risks of Covid.
