About 12 years ago, at an info session for my child's preschool, the question of measles vaccines came up. "It's not, like, *Ebola*," said the school's director, who was old enough to remember polio and should have known better.
I approached her privately after the session was over, and politely mentioned that Ebola's total mortality was in the tens of thousands, while measles has killed millions. She bluntly refused to process this information.
