HPV vaccine reduces infection, even in unvaccinated

The HPV vaccine not only has resulted in a decrease in human papillomavirus infection in immunised teens but also in teens who were not immunised.

The HPV vaccine not only has resulted in a decrease in human papillomavirus infection in immunised teens but also in teens who were not immunised.

"Infection with the types of HPV targeted by the vaccine decreased in vaccinated young women by 69%," says Jessica Kahn, MD, MPH, a physician in the division of Adolescent Medicine at Cincinnati Children's and lead author of the study. "Two of these HPV types, HPV-16 and HPV-18, cause about 70% of cervical cancer. Thus, the results are promising in that they suggest that vaccine introduction could substantially reduce rates of cervical cancer in this community in the future."
