HPV Vaccines Don't Work Against Existing Infection
According to a new study, cervical cancer vaccines such as Gardasil do not fight existing HPV infections. The focus of the vaccines will continue to be on young girls who haven't yet been exposed to the virus.
The findings, reported in the Aug. 15 issue of the Journal of the American Medical Association, support a recommendation in June from the U.S. Centers for Disease Control and Prevention that vaccination focus on girls 11 and 12 years of age, most of whom would not have already become sexually active.
