If you look at the Pfizer trials, (the scientific one, not the fact they were taken to court a few times and paid a pretty penny in compensations), their results are hardly “so clear”. 1 person died of covid in the control group, and 0 in the vaccinated group. If you know your statistics, the 95% or so positive outcome is due to relative and not absolute difference.
- gizmo686 5y agoThe trial was not designed to test the efficacy against death. It was designed primarily to test against confirmed covid-19 infection, with a secondary goal of testing against severe disease.

The only time blanket testing occurred was to make sure no one in the vaccinated group was going to get counted as a breakthrough case when they got covid before full vaccination. Otherwise they only tested participants when they presented with symptoms, thus "these data do not address whether vaccination prevents asymptomatic infection" [0]. Accordingly, it was not testing Covid-19 infection except to the extent that it presented significant symptoms. The trial also didn't address (not clear how it could have) your ability to keep passing the virus along once vaccinated.
