> What have we learnt from this study?

> Infection with HPV types covered by the vaccine (HPV16/18) has been almost eliminated. Before vaccination, the prevalence of HPV16/18 was between 15–17%, which has decreased in vaccinated women to < 1% by 2021. However, about one-third of women still had HPV infection with non-vaccine high-risk HPV types, and new infections with these types were more frequent in vaccinated than in unvaccinated women.

The conclusion seems to be that the vaccine is extremely effective at preventing infection by the strains included in the vaccine. One might reach a stretch conclusion and infer that the 9-valent vaccine would be even better as it would (probably) dramatically reduce the risk of several of the remaining “high-risk” variants.
