HPV Infection Rates Decreased in U.S. Teens After Vaccine Introduction, Study Shows

Researchers have documented a decrease in HPV infection rates among teenage girls in the United States after the introduction of the HPV vaccine. The study examined the prevalence of HPV infections in girls and women both before and after the vaccine became available.

The research focused specifically on vaccine-type HPV, the strains targeted by the immunization. The findings indicate a significant reduction in these strains among U.S. teens who received the vaccine.
