What's different with COVID vaccine is that hundreds of millions have been vaccinated, so obviously even if the percentage of side effects is tiny,  many many individuals will be affected. Many of the statistically less competent people are picking those numbers to show us how terribly the government acted. They leave aside the optionality: how many more people would have died or would have had serious side effects from the disease if the vaccine hadn't been rolled out? There is little rigor applied except for the rigorous calls against government intervention (which I support in general).
