Maybe you have been conditioned to react with extreme suspicion when somebody even dares to mention the word "vaccine", so you don't even read what people write and start imagining what they "must be meaning"? We live in an age of paranoia and hostility, even after the pandemic.

I'm incredibly happy that the people saying that the vaccines were dangerous were wrong. It's a shame they didn't protect people better, but in the end the pandemic ended just as expected, ie a super-contagious and much less lethal strain infected everybody. This is how the black plague probably ended, reading accounts from the time. Even if they didn't know anything about viruses then.
