I can understand skepticism, notably from a woman I know that had many unwanted bleeding and it seems she was not alone : https://pmc.ncbi.nlm.nih.gov/articles/PMC12407584

Although from this study the global vaccine output is positive, the personal one seems negative for a lot of people. Many still got COVID19 and the bleeding issue, but they can't compare to what would have happened without the vaccine.

Notably many for whom the basic understanding of "25% lower risk of all-cause mortality" doesn't mean anything.

- "What is it ? I had 1 chance to 1 million to die but with the vaccine it's 0.75 to 1 million ?"

- "No, out of 22 million vaccinated, 0.4% died but out of 6 million unvaccinated, 0.6% died !"
