If we had as trivial of vaccinations for smallpox, anthrax, and rabies as we have for HPV, I'd collect them all. One fewer risk in my life, and a finite reduction in the risk of everyone around me's life, with no downside at all.

1 pin prick * 340,000,000 people > 340,000,000 people * 6.1 cases of cervical cancer * 0.9 efficacy / 100,000 people

Your world view assigns equally negative utility to at most 18,214 shots as 1 case of cervical cancer.

Put another way: If you were told you had to either take a shot every day, or you are guaranteed to get cancer, would you really choose the cancer?

There is no human alive who has smallpox that you could catch it from, so getting vaccinated for it is pointless unless you think it's likely that some samples in a lab somewhere might escape.
