Fewer adult women are becoming infected with human papillomavirus (HPV), a trend that includes females who have never received the HPV vaccine, a new study reports.

It appears that enough women have gotten the HPV vaccine to create "herd immunity" that will provide some protection to females who go unvaccinated, said lead researcher Dr. Abbey Berenson.

"While vaccinated women have already had low levels of HPV infections for several years, we are now seeing a reduction in infections among women who have not received the vaccine," said Berenson, director of the Center for Interdisciplinary Research in Women's Health at the University of Texas Medical Branch in Galveston.

"This is further evidence that the vaccine is effective and emphasizes just how important it is for everyone who is eligible to get vaccinated," she added.
