Anyway, I think it's hard for informed consent on things like Gardasil. Every time I've seen it presented, it's billed as preventing cancer (which is true), but the full context isn't really given (that it's preventing cancer associated with HPV but not spontaneously occurring cancer). I would assume if it were better stated that Gardasil prevents cancers that arise secondary to sexually transmitted infections, it would likely reduce the rates of parents consenting to administration, which could be problematic from a public health standpoint, but challenging from a medical ethics standpoint of not giving a true picture for informed consent. My view, at least.
