HPV is a live vaccine but noninfectious..Noninfectious vaccines are considered to be a low risk during pregnancy. Additionally, studies in pregnant animals with the HPV vaccine found no increase in birth defects. Studies are ongoing with human exposures to the vaccine during pregnancy. The manufacturer of Cervarix®reported higher rates of miscarriage in women receiving the vaccine close to the start of their pregnancy. However, the rate of miscarriage was still within the rate of miscarriages expected for the general population (women who had not received the vaccine. To be conservative, you should wait until after pregnancy to complete any remaining shots in the series. Feel free to ask any queries.. Good day..
