This started years ago to slander the anti-vax crowd.

Realistically, it shouldn't matter to anyone but you if you're vaccinated. But, wait, what about people that can't get the shot? They rely on "herd immunity" (you sheep) to protect them so now you're getting jabbed for them.

I get it, it's nice that they get protection from our actions, but the narrarive has been twisted to make it seem like the default position that we're accountable for.
