Cancer statistics 2023 is out.
The incidence of cervical cancer 2012-2019 dropped a whopping 65% among women in their early 20s, the first cohort to receive HPV vaccine.
A vaccine that prevents cancer! It's amazing when you really think about it. 1/https://t.co/kmnmDwvoeS

The effort to get teens vaccinated against HPV started less than a generation ago. And it is paying off. Vaccinations provide direct protection and indirect protection in this case. Direct protection is a lower probability of a vaccinated individual getting HPV and then cervical cancer a decade or more later. Indirect protection means there are fewer opportunities for currently non-infected individuals to be infected from now vaccinated partners to then not spread it to future unvaccinated partners.
I would be surprised if we don’t see a decline in mouth and tongue cancers that can be attributed to HPV vaccination proliferation — could probably do a pretty cool analysis that leverages variation in county rate of vaccination a decade ago to get a plausible causal analysis.
