AntiVaxxers Take Note - Measles Kills, Because Of You
Every once in a while, there’s news of a measles outbreak. On the surface, they don’t involve large numbers of cases — there’s one in Minneapolis right now that has racked up 21 cases so far — and so people seem to wonder why these outbreaks are such a big deal.
