Parts of the country with requirements that adolescents be vaccinated against human papillomavirus (HPV) before entering school had higher HPV vaccination rates compared to nearby areas without such policies, a recent study in JAMA Pediatrics found. The findings suggest that school-entry requirements can help increase HPV vaccination coverage in the U.S., where these rates remain less than optimal.

In Rhode Island, where the HPV vaccine is required for school entry, the HPV vaccination rate among 13-to-17-year-olds was 91%, compared with an average of 78% in neighboring states without these policies. Similarly, in the District of Columbia, which has such a policy, the immunization rate was 89%, compared with 72% for nearby states that did not have school-entry requirements for HPV vaccination. The study used data from 2008–2017 from CDC’s National Immunization Survey and was authored by Jamie S. Ko et al.
