How Many Have Died From COVID Vaccines?
Between mid-December 2020, when the first COVID-19 shots were rolled out, and April 23, 2021, at which point between 95 million and 100 million Americans had received their COVID-19 shots, there were 3,544 reported deaths following COVID vaccination.2
If we go with the higher number, 100 million vaccinations, that would be about 354 deaths per million.
Of course not all of the deaths recorded shortly after vaccination were caused by vaccination, but it is also true that the vaccine likely killed people outside of the reporting window and the reporting is voluntary, not mandatory so not all deaths are reported.
Even if we exclude any unreported deaths and toss out 2/3rds of those that are reported we are coming up with 100 times as many deaths as "the most dangerous" vaccine in the world.
