evidence: Reports of serious health issues after HPV vaccination were consistently rare—around 1.8 per 100,000 HPV vaccine doses, or 0.0018%. A total of 758 serious health problems that arose after HPV vaccination were reported in VAERS during that time. Meanwhile, the rate of nonserious health issues following HPV vaccination reported in VAERS dropped from 43 to 28 per 100,000 vaccine doses. [...] Another CDC-funded vaccine safety program, the Vaccine Safety Datalink (VSD), also performs vaccine safety studies, including those based on reports to VAERS. A recent VSD study of the 9-valent HPV vaccine (Gardasil 9), for example, tracked new vaccinations over a 2-year period and identified no new safety issues. [...] HPV vaccines can cause pain, swelling, and redness where the shot was given, as well as headaches, tiredness, and nausea. The most common serious side effects of HPV vaccination are dizziness and fainting. There is no evidence that HPV vaccines lead to infertility or autoimmune diseases, although these are common myths.
