Chickenpox Is Really A Big Deal

"According to the CDC, in 2014, 95% of children from 13 to 17 years old had received at least one dose of the Varicella (chickenpox) vaccine. (Kids are supposed to receive two doses.) That's a good thing because, contrary to popular belief, chickenpox can be serious for some people. It killed roughly 100 to 150 and hospitalized more than 10,000 Americans every year in the early 1990s."
