coffee > The virus has become so much more tamer because of the mutations not because of vaccines
while general theory says that viruses are generally mutating to weaker versions, that may not be true early on. For example, delta was worse than original Wuhan and Bidenistas were not prepared for that. but I did not see that later versions are milder, it is just accumulated immunity both from both vaccines and infections. With most of population exposed, their next infection produces less viruses and also the asymptomatic period decreases.
See, for example, devastating effect of European viruses on Native Americans. Lack of immunity is the most important factor.
