Yeah it makes more sense for vaccines that are, well, better at being vaccines. Something like MMR that actually is effective enough to create hurd immunity. Small pox vaccine was so good it eradicated the disease completely. Covid vaccines are more like flu vaccines - sometimes they work sometimes they don’t. It’s still better than nothing for >95% of people. There are those who respond badly to the covid vaccine too, so it’s technically a gamble either way. While the science says it’s better odds to have the vaccine than not, I can’t force people to take that risk with me.
