evidence: Like any vaccine or medicine, HPV vaccines can cause side effects. The most common side effects are pain, redness or swelling in the arm where the shot was given, dizziness, fainting, nausea and headache. HPV vaccination does not usually cause serious side effects. The benefits of HPV vaccination far outweigh any poossible risk of side effects. [...] Reports of blood clots, strokes, heart attacks, chronic fatigue syndrome, infertility or premature ovarian failure, and even death have occurred after receipt of this vaccine; however, studies of people who did and did not get the vaccine have shown that none of these problems were caused by the HPV vaccine. [...] No. There is no information that suggests the HPV vaccine will cause problems with the ability to get pregnant. In fact, getting vaccinated and protecting against cervical cancer can help women have healthy pregnancies and have healthy babies. Not getting the HPV vaccine leaves people without protection to HPV infection; for women, this could lead to cervical cancer. The treatment of cervical cancer (hysterectomy, chemotherapy, and/or radiation, for example) could leave a woman unable to have children. Even the treatment of cervical pre-cancers caused by HPV can cause preterm labor or problems at the time of delivery.
