The problem is that 25% lower risk of all-cause mortality is too big to be explained solely by the vaccine. The reduction is similar when excluding deaths due to COVID-19, and is probably driven by people who got the vaccine being different in some ways that the observational study isn’t controlling for.
Not getting the vaccine is statisically correlated with distrust in traditional medicine, and suceptibility to giving undue attention and credit to unfounded and unsound practices.
