In the past the vaccines were tested with control groups made up of volunteers who knew about the potential health risks before going through the clinical trials. These vaccines were only distributed after researchers were sure that there was minimal chance of adverse reactions.

But things have changed over the years. Previously it was stated that children should only be vaccinated after a certain age - now we're injecting them almost as soon as they're out of the womb (and autism rates are increasing? Funny how that works...) Some of the things that the pharmaceutical companies are recommending make little sense, like a vaccine that is designed to prevent a type of cervical cancer that fewer than 1% of women get... and we're giving this to young men? (Incidentally, the chance of being made infertile because of the vaccine is higher than the chance of an unvaccinated woman contracting the cancer. Funny how that works....)

I think COVID was a breaking point for many people. It was rushed out to the public without the same thorough testing these vaccines received in the past - which typically took years. Couple that with various governments attempting to force people to get the vaccine (" if you don't get the shot you get fired") and the whole thing made a lot of people say "maybe those anti-vaxxers were onto something...."
