New Vaccine Recommendation Cuts Number Of HPV Shots Children Need

You’d think that a vaccine that protects people against more than a half-dozen types of cancer would have people lining up to get it. But the human papillomavirus (HPV) vaccine, which can prevent roughly 90 percent of all cervical cancers as well as other cancers and sexually transmitted infections caused by the virus, has faced an uphill climb since its introduction more than a decade ago.

Now, with a new dosing schedule that requires fewer shots and a more effective vaccine, clinicians and public health advocates hope they may move the needle on preventing these virus-related cancers.

In December, the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices recommended reducing the number of shots in the HPV vaccine from three to two for girls and boys between the ages of 9 and 14. The recommendation was based on clinical trial data that showed two doses was just as effective as a three-dose regimen for this age group. (Children older than 14 still require three shots.)

The study was conducted using Gardasil 9, a version of the vaccine approved by the Food and Drug Administration in late 2014. It protects against nine types of HPV: seven that are responsible for 90 percent of cervical cancers and two that account for 90 percent of genital warts.
