Had that happened, would anybody be able to deduct that they booed the vaccines? I think that would be a good thing because people are dying of the vaccine meaning people can see the crazy Anti-Vaxxers on Fake News being Anti-Science.
After that, they can see and continue to see people scientifically die and die and die some more. Sure, too many people can live in denial and repeat the talking points including that people die of Covid even after getting vaccinated. Seeing people boo something and then seeing a bunch of people die from it could perhaps wake up some people.
Will it wake up enough people is the question. I don't know the answer but it doesn't hurt to try as billions of people are likely to die before 2025 due to these vaccines, assuming we can't turn this ship around fast enough.
