It will protect your uterus too.
I remember when my gf took her twin boy and girl to get the HPV shot. After it was over, she told them what it prevented. Zach spoke up from the back seat....'wait a minute. Do I even HAVE one of those??'. Of course the answer was no, you don't. So then came the indignant reply "so what did I just do that for? You had a coupon didn't you! Buy one and get one free!!" he was all kinds of pissed off and blamed his sister for him getting the shot.
Sounds like he knows his mom...coupon. lol
I get the flu shot late October, early November.
