Applicable groups for cervical cancer vaccine

Cervical cancer vaccine is suitable for women aged 9-45, and the optimal age for vaccination is 9-26 years old. Cervical cancer vaccine mainly prevents human papillomavirus infection and reduces the incidence of cervical cancer. HPV testing is not required before vaccination, but pregnancy and acute infection periods need to be avoided.

1. Adolescent women

The World Health Organization recommends 11-12 years old as the optimal starting age for vaccination, when the immune response is strong and most people are not exposed to the HPV virus. The domestic bivalent vaccine Xingkonin, the imported quadrivalent vaccine Jiadaxiu, and the nine-valent vaccine Jiadaxiu 9 are all suitable for this group of people and can effectively prevent high-risk subtype infections such as HPV16/18. Parents need to complete the full course of vaccination before the girl has sex for the first time, usually 2-3 doses are needed.

2. Adult women

Vaccination for women aged 27-45 can still obtain protective benefits, especially for those who are uninfected or infected with a single subtype. The quadrivalent vaccine can prevent genital warts, and the nine-valent vaccine covers 90% of oncogenic HPV types. The safety of vaccination for lactating women has been verified, but it should be noted that adverse reactions such as local redness, swelling, and low-grade fever may occur after vaccination, which usually resolve spontaneously in 2-3 days.

3. Special health conditions

People with low immune function, such as HIV-infected people and patients with autoimmune diseases, are more in need of vaccination, but the immune response may be weakened. It is necessary to evaluate the stability of the disease before vaccination and avoid vaccination during the peak period of immunosuppressive treatment. Postoperative vaccination in patients with cervical intraepithelial neoplasia reduces the probability of recurrence but does not treat existing infection.

4. Male vaccination

Some regions have approved male vaccination with quadrivalent or nine-valent vaccines to prevent anal cancer, oropharyngeal cancer and reduce virus transmission. The optimal age for male vaccination is 9-26 years old, which can block genital warts caused by HPV6/11 types. However, men are currently not included in the immunization program in China and must choose to be vaccinated at their own expense.

5. Vaccination taboos

People with severe allergies to vaccine components such as yeast protein are contraindicated, and patients with moderate to severe acute diseases should postpone vaccination. It is recommended to observe for 30 minutes after vaccination to prevent allergic reactions and avoid vaccination with other vaccines at the same time. Those who have completed the full course of vaccination do not need to receive higher-priced vaccines, but they need to undergo regular cervical cancer screening.

After vaccination, you still need to maintain a healthy lifestyle, including using condoms to reduce cross-infection, regular TCT and HPV combined screening, and avoiding smoking and other cancer-causing factors. Pay attention to supplementing your diet with carrots rich in vitamin A, nuts with vitamin E and high-quality protein, and moderate exercise to enhance immunity. If persistent high fever or severe allergic reaction occurs after vaccination, timely medical treatment is required.
