HPV Remains Effective 8 Years Later

‚ÄčThe study, "Long-Term Study of a Quadrivalent Human Papillomavirus Vaccine," appearing in the September 2014 issue of Pediatrics (published online Aug. 18), examined whether the HPV vaccine remains effective 8 years after initial vaccination.

Researchers followed boys and girls who were vaccinated with the HPV vaccine between the ages of 9 and 15. The results showed that these preadolescents and adolescents still showed vaccination-induced anti-HPV response 8 years later and that no new, significant adverse effects were reported. Among these preadolescents and adolescents who received the HPV vaccine at a mean age of 12, none developed disease related to the HPV types covered by the vaccine.

According to the CDC, each year HPV vaccination rates remain near the current level of 33 percent, an additional 4,400 women will be diagnosed annually with cervical cancer.

Study authors conclude that high uptake of the HPV vaccination is paramount in reducing HPV-related cancers and that results of this study should reinforce the national recommendations for HPV vaccination of all preadolescents and young adolescents.

Editor's Note: This issue also includes another article on HPV vaccination: "Missed Opportunities for HPV Vaccination in Adolescent Girls: A Qualitative Study."
