Wang Linhong introduced that the currently available HPV vaccines in my country include bivalent vaccine, quadrivalent vaccine and nine-valent vaccine, and the age range of 9 to 45-year-old women, but the most high-risk HPV types that cause cervical cancer are subtypes 16 and 18, so bivalent vaccines can prevent more than 70% of cervical cancers, which is the vast majority of cervical cancers.

She pointed out that five HPV vaccines have been approved and registered in my country, including three imported HPV vaccines and two domestic vaccines. Data from the National Routine Vaccine Statement shows that from 2018 to 2020, the number of HPV vaccinations has increased year by year, from 3.417 million in 2018 to 12.279 million in 2020. However, on the whole, the current HPV vaccine is still in short supply. The number of school-age women in my country is relatively large, so the HPV vaccination rate is still at a relatively low level.

Wang Linhong emphasized that the HPV vaccine has the best protective effect on young women who have not yet been infected with the virus. The World Health Organization recommends girls aged 9 to 14 as the primary vaccination group. The earlier the vaccination, the better the effect. of.

“Therefore, under the current situation of tight supply of HPV vaccine, there is no need to miss the best vaccination time because of waiting for a higher-priced vaccine.” Wang Linhong said.
