> had less registered side effects than only BioNTech in one year Isn't this just some kind of bias? For example reporting and spreading information is easier than it was in 1970s, or that we take any suspected side effect for real these days? > that barely protect some of the people The ratio in ICUs is currently 1:5 to 1:10 in my country, showing a protection of 80 to 90% of the people (https://ockovani.opendatalab.cz/statistiky https://ockovani.opendatalab.cz/statistiky). In other countries, for example Israel (https://datadashboard.health.gov.il/COVID-19/general https://datadashboard.health.gov.il/COVID-19/general), it's about the same. That's not "barely" and "some", I think this is comparable with efficiency of other vaccines.
