Hpv vaccination what do you think?

What do you think about the HPV Vaccination? Do you agree with it? Personally I do, I think anything that can help prevent cancer is a good thing I don't see how people can say it promotes , you also get a rubella vaccination at school to help protect your baby when your pregnant, which obviously you have to have to get pregnant so why is that ok? I am waiting for a colposcopy as have severe abnormalities on my smear test and I wish I had of been able to have this vaccination.
