Anti-vaxers love to talk about how sometimes people who have been vaccinated might get sick anyways.
But that just means to prevent an *outbreak* you need even higher rates. But I feel like that's the thing they don't understand: what an outbreak is.. these things used to just burn through cities and towns. How you had to have three kids so maybe two could grow up.
How people used to not always name babies too soon because... well it might be less painful if they died.
