I have a question about it. How come on the ads it says it is for age 26 and under? Why wouldn't it work for me at 33? Do they assume I have already had the virus? I just think that every woman should get it if it even only lowers the risk of getting cancer by a little bit. Is there something I'm missing about how it works? I plan on asking my Dr about it when my youngest goes in for his next set of vaccines, but thought you guys might have some thoughts.
