Human papillomavirus vaccine Pregnancy and Breastfeeding Warnings

Human papillomavirus vaccine is also known as: Cervarix, Gardasil, Gardasil 9

Human papillomavirus vaccine Pregnancy Warnings

Human papillomavirus vaccine has been assigned to pregnancy category B by the FDA. Animal studies have revealed no evidence of impaired female fertility or harm to the fetus. During clinical trials, women who were found to be pregnant before completion of a 3-dose regimen of human papillomavirus vaccine were instructed to defer completion of their vaccination regimen until resolution of the pregnancy. The proportions of pregnancies with an adverse outcome were comparable in subjects who received human papillomavirus vaccine and subjects who received placebo. Human papillomavirus vaccine is only recommended for use during pregnancy when benefit outweighs risk. Merck & Co., Inc. maintains a Pregnancy Registry to monitor fetal outcomes of pregnant women exposed to the GARDASIL brand of human papillomavirus vaccine. Patients and health care providers are encouraged to report any exposure to GARDASIL during pregnancy by calling (800) 986-8999.
