America is a bit behind on the HPV vaccination trend. I'll explain why that's a problem.
Remember when I explained how polio isn't really a thing anymore in the U.S.?
That's because we invented and then distributed vaccines to as many people as possible. Today, polio's gone from a modern scourge to a hazy shadow, infecting fewer than three dozen people in 2015. And even with a recent set back in Nigeria, we're incredibly close to making polio a thing of the past.
