Human papillomavirus (HPV) is currently one of the most common sexually transmitted infections, according to its carcinogenicity is divided into high-risk genotypes and low-risk genotypes, research has confirmed that carcinogenic HPV type continuous infection leads to a higher incidence of condyloma acuminatum and cervical cancer, while increasing the oropharyngeal cancer, vaginal cancer and other related cancer risk. HPV vaccines have been widely introduced worldwide to prevent cancers of the lower genital tract such as cervical, anal and vulvar cancers. For different types of HPV vaccine, divided into domestic bivalent, imported bivalent (GlaxoSmithKline), quadrivalent (Merck) and nine-valent (Merck) HPV vaccine, four vaccines all prevent HPV 16/18 high-risk type infection disease, and the four and nine-valent HPV vaccine prevention genotypes are different, and different price number of protection rates, vaccination objects and immunization procedures are slightly different. At the same time, studies have shown that women after HPV vaccine, arm redness, swelling, heat and pain have a high incidence of adverse reactions, often accompanied by menstrual disorders, sleep problems, emotional irritability, fever, dizziness, headache and other adverse reactions risk, so we plan to design a multicenter cohort study to evaluate the effectiveness of HPV vaccine with different prices. At the same time, the adverse reaction symptoms of HPV vaccine in the female population of appropriate age were monitored.
