I actually know more people who survived covid 19 than not with no long term effect unvaccinated. This was before the vaccines were widespread. Because of covid, by wearing mask everywhere last season, regular flus and colds were almost nonexistent. I don’t know if that is a good thing by not building antibodies, next thing, we might have killer flus and colds. Science technology is pretty good so don’t be afraid of vaccinations, if you got it for other diseases, makes no sense if you don’t get it for Covid-19.
