You might want to also consider that maybe they want the people to know that vaccines are dangerous yet force them to take more regardless.

It's one of those Michel Foucault control over bodies (i.e. humans) thing, power over life and death, where the state power is so immense that people will obey it even if they knew it could cause their death. I believe this was a big part of the covid hoax. Many people took the vaccines in spite of not wanting to just to keep their jobs.
