The problem with mRNA vaccines is that we did not downplay and censor charlatans enough. We allowed anti-vax rhetoric to spread like wildfire on Twitter, Facebook, and the like. Our scientists and doctors actually humored these people, and that was a huge mistake.

As soon as you tell an anti-vaxxer something like "there are risks, but..." all they hear is "aha!! I knew it was poison!".

Nobody on planet Earth said that the vaccine was 100% safe, nor that it was 100% effective. Because no vaccine, and no medicine, is. But we allowed people to revel in their own fear and anti-establishment mentality, and because of that, a lot of people died that did not need to.
