> since the vaccine is widely available for all...
They sure as fuck aren't. There's three countries in the world where the percentage of fully vaccinated is over 50% (two of which have <1m people, and the third one being Israel that doesn't even pretend to count Palestinians). In France that number is 14%. In my country we haven't even reached 1%.
> If the vaccine works, why in the world do you care who doesn't want to take it?
Because there are millions of people that can't receive one due to the weaker immune system, which is where herd immunity is supposed to kick in.
If the vaccine works, why in the world do you care who doesn't want to take it?
