> Also, the eligibility criterion of not vaccinating people above certain age is NOT valid. I mean, sooner better. But if you are adult and there is any chance that you ever get a new sexual parter, get a vaccine.

The eligibility criterion has primary been about controlling cost to focus about the groups where the societal effect is greatest.

I expect it may gradually get broadened, but most places you can also get it privately even if you fall outside those ages.

E.g. in the UK, most private providers will vaccinate you up to 45, and at least some private providers will give you the vaccine with no upper age limit (and a lower age limit of 9) at a relatively reasonable cost (~180 pounds per dose - 2 to 3 doses)

Prioritization makes a lot of sense.

At the same time, guidelines go differently, e.g. "Vaccination is not recommended for everyone older than age 26 years." from https://www.cdc.gov/vaccines/vpd/hpv/hcp/recommendations.htm.... These things propagate among doctors and most of them do not recommend vaccination (contrary to modern research data!)
