Introduction:

The nine-valent HPV vaccine is a vaccine used to prevent cervical cancer caused by human papillomavirus (HPV) infection. It can prevent more than 90% of cervical cancer. Vaccines usually require 3 injections and take up to 6 months to be effective.

The vaccine was approved for marketing in the United States in 2014 and launched in China on April 28, 2018. Vaccination is primary prevention, and screening is secondary prevention. Both are equally important. Cervical cancer screening measures should not be relaxed because of vaccination.

The nine-valent HPV vaccine has good immunogenicity. After completing the three-dose vaccination process, the seroconversion rate of relevant types of serum antibodies can reach almost 100%. One month after completing the vaccination program, the peak geometric mean antibody titer can reach 100 times the antibody level after natural infection. In the next 2 months, the value drops to 10 times and remains at a plateau. The antibody levels of the vaccine can be maintained for at least 4 years.

Clinical trials have shown that vaccination with the nine-valent HPV vaccine can produce good protective effects, and can effectively reduce persistent HPV infections of corresponding types and precancerous lesions of the cervix and genitals. The protective efficacy can reach 90%. %above. The nine-valent HPV vaccine contains VLPs of HPV-6 and HPV-11 types and has a good preventive effect on genital warts.
