#Vaccines' indirect benefits overlooked in battle over 'medical freedom' https://www.statnews.com/2026/03/19/vaccine-success-widespread-hidden-benefits-make-skepticism-possible/ “The #HPVvaccine is a medical wonder. As noted above, it is preventing cancers in both women and men. Human papillomaviruses, which are transmitted through sexual contact, cause a number of urogenital cancers — cervical cancer, anal cancer, penile cancer — and oropharyngeal cancers.
HPV vaccines were originally licensed for girls only. But it soon became apparent that boys were benefiting from them too.
“I think HPV is one of the most elegant herd immunity stories that we have, because the indirect protection showed up so clearly and so quickly, in a population that wasn’t even targeted by the original program,” Scott said.
Within five years of the rollout in Australia — a campaign that only targeted girls — researchers there were reporting significant declines in genital warts (caused by human papillomaviruses) in heterosexual men. A study from the U.S. found that oral infections with HPV strains covered by the vaccine dropped 38% between 2009-2010 and 2015-2016 in unvaccinated men, during a time when rates of HPV oral infections with strains not included in the vaccine went unchanged.
Many countries now vaccinate both girls and boys against HPV.”
