At what age should you get the cervical cancer vaccine?

Cervical cancer vaccine is usually given between the ages of 9 and 45, and the best age for vaccination is between the ages of 9 and 14 before having sex. Cervical cancer vaccines mainly include bivalent, quadrivalent and nine-valent HPV vaccines, which respectively prevent different subtypes of human papillomavirus infection. Vaccination needs to be selected according to age and vaccine type.

The bivalent HPV vaccine is suitable for women aged 9-45 and can prevent infection by HPV types 16 and 18. These two subtypes are associated with more than 70% of cervical cancers. The quadrivalent HPV vaccine is suitable for people aged 20-45. In addition to preventing HPV types 16 and 18, it can also prevent genital warts caused by HPV types 6 and 11. The nine-valent HPV vaccine is suitable for women aged 16-26, covering high-risk subtypes such as HPV16, 18, 31, 33, 45, 52, 58 and HPV types 6 and 11, with a more comprehensive preventive effect. Vaccination needs to be completed in 2-3 doses. People aged 9-14 years usually receive 2 doses, 6 months apart. ； Those over 15 years old need to be vaccinated with 3 doses, completed at 0, 1-2, and 6 months respectively. Minor reactions such as local redness, swelling, and fever may occur after vaccination, which usually resolve spontaneously in 2-3 days.

It is recommended to consult a doctor before vaccination to clarify your own health status and vaccination contraindications. Pregnant women should postpone vaccination, and those who are allergic to vaccine components or have immune deficiencies should be cautious. Even if you are vaccinated, you still need to undergo regular cervical cancer screening because the vaccine cannot cover all high-risk HPV subtypes. The risk of infection can be further reduced by practicing good sexual hygiene, avoiding early sex, and having multiple sex partners.
