Covid19 already has well-known short- and mid-term downsides for >> 1% of grown-ups infected. The hard “downsides“ are so dangerous that we had trouble to properly treat the sick.

BNT/Pfizer has so little short- and mid-term downsides that it is difficult to properly spot them statistically, even after about a half billion vaccinations.

Both may have long-term downsides, but: all vaccinations we know didn‘t have any long term downsides. The problems were either visible immediately or they were relatively rare so that they were only detected after a significant number of people had been vaccinated. The downsides of Covid-19 are not rare compared to that, for any age. There is no reason to consider the vaccine more frightening than Covid19. On the other hand everything about the virus SARS-CoV-2 and the disease Covid-19 is experimental because this virus has not been tried on humans until now! The infection it causes is way more complex than the immune reaction BNT/Pfizer causes and it definitely would not have passed a phase-1 study.

If you are afraid of BNT you should basically panic about Covid-19.
