You're again playing very fast and loose with numbers there. The average female life expectancy is 81. And the shots only matter during the window of your life where cervical cancer is remotely relevant, which is during a typical sexual window where somebody may have multiple partners. 50 was already pushing the limits there, but I accepted it because even with that exaggeration, it's not close. But at some point you've got to start being remotely reasonable. And this is again before we even get into real efficacy, side effects, and other issues which matter quite a lot with diseases that have as low an impact as cervical cancer. E.g. a quick search shows a rate of severe side effects from the vaccines at 1.8 per 100k (which you need to multiply for a multi-shot regime). That matters quite a lot when the death rate from cervical cancer is 2.2 per 100k.

And more generally, I think converting this issue into weeks starts to emphasize how broken a metric statistical value of life is. Nobody, again outside of millionaires, is paying thousands or even hundreds of dollars for one more week of life expectancy. Even if they wanted to, the overwhelming majority of people just don't have that degree of disposable wealth. It's akin to you ask people how much they'd be willing to pay to e.g. deal with climate change, and they give some ridiculously large number. But then when it comes time to really pay, and not hypothetically pay, that number suddenly becomes quite close to $0.
