The 9-valent HPV vaccine for women is a vaccine that prevents human papillomavirus (HPV) infection. It covers nine high-risk and low-risk HPV subtypes, effectively reducing the risk of diseases such as cervical cancer and genital warts, making it an important protective measure for women's reproductive health. If you have any questions about vaccination or experience cervical discomfort, it is recommended to seek medical advice promptly.

In terms of subtype coverage, the 9-valent HPV vaccine includes two low-risk subtypes (type 6 and type 11) and seven high-risk subtypes (type 16, 18, 31, 33, 45, 52, and 58). The low-risk subtypes primarily prevent genital warts, while the high-risk subtypes help reduce the risk of malignant conditions such as cervical intraepithelial neoplasia and cervical cancer caused by HPV infection.

Regarding eligibility and administration, the 9-valent HPV vaccine is recommended for females aged 16 to 26. It is typically administered in three doses according to a 0-, 2-, and 6-month schedule. The vaccine works by stimulating the body to produce protective antibodies. It can be given even after becoming sexually active. HPV testing is not required before vaccination, but regular cervical screening should still be performed after vaccination.

In daily life, maintain good sexual hygiene and avoid having multiple sexual partners. After vaccination, keep the injection site clean and dry, avoid strenuous exercise, maintain a regular sleep schedule, and strengthen immunity to help sustain optimal immune protection.
