Pregnancy one month after the cervical vaccine is recommended to keep the child with continued observation and regular labor and delivery tests. Available evidence does not suggest that this vaccination increases the risk of adverse pregnancy outcomes, so pregnancy detected after HPV vaccination can be continued after consultation with a professional obstetrician/gynecologist. Several inactivated HPV vaccines are available worldwide, including the 2-valent, 4-valent, and 9-valent vaccines; due to limited safety information, vaccination with any HPV vaccine during pregnancy is not recommended, and if pregnancy is detected after initiation of the vaccine series, subsequent vaccinations should be administered after delivery. Most of the data on HPV vaccination during pregnancy are on the 4-valent HPV vaccine. One study showed that among 3819 women who became pregnant during a trial of the 4-valent HPV vaccine, the incidence of composite adverse pregnancy outcomes (spontaneous abortion, late stillbirth, and congenital anomalies) was similar in those who received the vaccine compared with unvaccinated controls (22.6% vs. 23.1%). A population-based study that included all pregnancies in Denmark over an 8-year period, including nearly 7,500 women who received at least 1 dose of 4-valent HPV vaccine during pregnancy and more than 5,000 deliveries, showed that 4-valent HPV vaccination was not associated with an increased incidence of spontaneous abortions, stillbirths, or infant deaths; there was no correlation between spontaneous abortions and the number of doses of vaccine or the timing of the vaccination. Therefore, if pregnancy is detected after HPV vaccination, the pregnancy can be continued after consulting with a professional obstetrician and gynecologist, and the obstetric examination can be strengthened during the pregnancy, so that any problems found can be dealt with in a timely manner.
