evidence: Raw numbers of hospitalizations or deaths among those who are vaccinated are not a good indicator of whether vaccines are effective. If the large majority of a population is vaccinated, it’s not surprising if most deaths are among the vaccinated. But social media posts misuse data from the U.K. to suggest the COVID-19 vaccines don’t work. Epidemiologists and biostatistics experts have been cautioning that as more and more of a population gets vaccinated, we’ll likely see more deaths from COVID-19 among the vaccinated. It’s simply math. The vaccines aren’t 100% effective — no vaccine is — so some deaths are expected. And if there are relatively few people still unvaccinated, the raw numbers of deaths are likely to show more deaths among the vaccinated. [...] "BE IN THE KNOW: the vast majority of people (7 out of 10) who died from the COVID-19 virus in the UK were fully vaccinated," one Facebook post reads, accompanied by a clip of Alex Berenson citing the data on "The Joe Rogan Experience" podcast on Oct. 12. Berenson, an author and former New York Times reporter, has been banned from Twitter for violating its rules on COVID-19 misinformation. We wrote about one of his tweets on the COVID-19 vaccines earlier this year. In the Facebook clip, Berenson correctly cites the U.K. numbers but presents them as something surprising.
