HPV Vaccine in Pregnancy No Longer Contraindicated

SAN DIEGO — The human papillomavirus vaccine, although still not recommended for use in pregnancy, is no longer listed as contraindicated by the Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices.

“This may lessen the concern when a woman inadvertently receives a dose before learning she is pregnant,” Dr. Hal Lawrence said at Perspectives in Women's Health sponsored by FAMILY PRACTICE NEWS, OB.GYN. NEWS, and INTERNAL MEDICINE NEWS.

“Given time and more data, multiple doses of the vaccine may prove to be safe during pregnancy, offering clinicians an opportunity to initiate or complete the three-dose series during a period of routine office visits,” added Dr. Lawrence, vice president for practice activities, American College of Obstetricians and Gynecologists.

For now, however, neither intentional initiation of the vaccine series nor delivery of doses two and three during pregnancy is recommended, according to updated information available from the CDC's Guidelines for Vaccinating Pregnant Women, available at www.cdc.gov/vaccines/pubs/pre-guide.htm

The HPV vaccine contains neither live nor attenuated viral particles; instead, it contains particles engineered to resemble the L1 protein on the virus's outer capsule.

Although it provokes a robust immune response, “it does not have any actual viral activity,” said Dr. Lawrence. To date no adverse events related to the mother or the developing fetus have been associated with administering the vaccine during pregnancy.

In an interview, Dr. Lawrence emphasized that the data are limited. “What we are really saying is that while no adverse events have been reported, there is not enough information to recommend HPV vaccination in pregnancy,” he said.

Dr. Lawrence said that clinicians with patients who received the HPV vaccine during pregnancy are encouraged to call the HPV Vaccine Pregnancy Registry at 800-986-8999 to add to the information base. As HPV vaccinations during pregnancy are identified and pregnancy outcomes are tracked, the CDC and other organizations may reevaluate use of the vaccine during pregnancy.

In other news regarding HPV vaccines, Dr. Lawrence cited recent data showing partial blocking of 10 additional HPV strains, in addition to HPV 6, 11, 16, and 18, the four covered by the quadrivalent vaccine. “This may boost protection [against cervical cancer] to 90%,” he said.

HPV is also responsible for the majority of anal and vulvar cancers in young women and for head, neck, and oral cancers, any of which could potentially be prevented with the HPV vaccine, he said.
