The way the discourse has evolved in the past two years is unbelievable. You see people deride fundamental concepts of democracy like freedom, the right to protest, and bodily autonomy.
If the vaccines are effective, then the only people at risk are those that refuse to get it. Everyone is subject to the consequences of their autonomous choice alone.
The same is true for potential long term negative effects of the vaccines. Those that refuse to get it are subject to the potential long term effects of COVID, if they get it. And those that get the vaccine are guaranteed to be subject to the long term effects of having done so.
Either you believe the vaccines work or you don't. The variants dominated highly vaccinated places like the UK and Israel, so don't blame the unvaccinated for bringing it about. The selective pressure applied to the virus by leaky vaccines is far greater than natural immunity.
Vaccines aren't a binary 100% or 0% effective tool, it's somewhere in the middle. If my 10 coworkers all get the vaccine, it reduces the probability of me contracting the virus, even if I got vaccinated myself. There is a communal aspect to the vaccine that you are missing here.
Leaky vaccines work the same way antibacterial soap did to create MRSA. They leave enough virus present to mutate to evade the mechanism originally intended to fight against it, so only the most robust mutations remain.
