US EditionHPV Vaccine Protecting Against Infections, Even Among Unvaccinated
HPV vaccination rates reached 82% in a 17-year study showing infections dropped 76% to 98% among vaccinated women and fell 72% to 76% in unvaccinated women.
- A 17-year study published on September 29, 2025, found the HPV vaccine protects young women from cervical-cancer-causing infections in Cincinnati.
- Over a 17-year period from 2006 to 2023, researchers monitored a group of young women aged 13 to 26 in Cincinnati as HPV vaccination coverage among them increased from none to over 80%.
- HPV infections fell dramatically by 98.4% among vaccinated women and decreased by 71.6% to 76% among unvaccinated women, indicating strong herd immunity protection.
- Dr. Jessica Kahn highlighted that HPV vaccines demonstrate strong effectiveness outside of clinical trials, even among higher-risk populations, and that widespread vaccination contributes to herd immunity, which helps protect those who are unvaccinated by reducing the spread of the virus.
- These results suggest expanding vaccine uptake and ensuring screening access could help eliminate cervical cancer globally, a major public health victory.

HPV vaccination drives cervical cancer rates down in both vaccinated and unvaccinated people
Researchers have found that human papillomavirus (HPV) vaccines are highly effective at reducing cervical cancer-causing infections and can offer herd immunity, reinforcing previous research and highlighting the need for a global HPV vaccine rollout.
Long-term study on HPV vaccinations finds evidence of herd immunity
A 17-year study on HPV vaccinations found evidence of herd immunity. As vaccination rates against HPV rose from 2006 to 2023, infections even among unvaccinated women declined significantly, researchers say.
Study shows HPV vaccine protects vaccinated — and unvaccinated
A large, long-term study led by an Albert Einstein College of Medicine researcher has found that the introduction of the human papillomavirus (HPV) vaccine in community settings is highly effective in protecting young women from infections caused by the cervical-cancer-causing virus—including women who didn’t even receive the vaccine. The study was published today in JAMA Pediatrics.
