> If someone refuses a vaccine and then passes on a virus to someone else, who dies

Why wasn't that other person vaccinated?

Some people can't take vaccines because of allergic reactions. Other people have weakened immune systems and so the effect of vaccines is low.

For those people, it's the group that protects them. But of course you always have selfish people that only care about themselves. It was nice to see the amount of selfish people was pretty low in my region, and we got about a 80% vaccination rate.
