The unvaccinated worldwide are likely even now creating a potential extinction event of humans here on earth through an as of yet unknown future variant

This is the problem the whole world faces.

On the one hand even if you forced the vaccination of everyone in Europe and the U.S. and Canada and Australia and New Zealand it wouldn't be enough to stop the next killer Variant (likely an offshoot of the Delta or Delta plus) coming from someone dying of it somewhere on earth that spreads it to even one person while they are dying. And according to immunologists this is happening not in big cities but in remote corners of the world for some reason as variants arise one by one and wipe out whole segments of the human race worldwide.

Or what is happening with the delta and delta plus is that now people are getting senile dementia from Covid so they cannot work or function anymore to care for themselves worldwide too. So, which is worse? Dying of Delta Covid or never being able to care for yourself ever again because you have Covid dementia?
