longitudinal HPV type distribution in Finland

As part of the RISCC project, Pimenoff et al. have just published a paper on the longitudinal HPV type distribution detected from cervical swabs up to eight years after the initiation of a community-randomized HPV vaccine trial in Finland (N=22,000). Using the non-vaccinated communities as reference, we observe that in those communities where girls alone or both girls and boys were vaccinated, HPV vaccine types had largely decreased but the oncogenic HPV types not included in the vaccine showed significantly increased ecological diversity and prevalence eight years post-vaccination in the gender-neutral vaccination communities compared to the girls only vaccination communities. You can find a visual representation of this process in this video.
