Hetty, there's no proof the STD causes cancer. There's not even that strong a causal relationship. You are not safe from cervical cancer. Yes, you can fight a few strains of HPV more quickly, but you are not immune to cancer.

I'm interested if anyone has done a follow up study on the vaccine and sexual behaviour risk. Not to say those with the vaccine are doing things wrong, nor those without the vaccine, just curious as to how the vax and perceived risk affect sexual and contraception choices.
