Bivalent HPV vaccine is "enough", it is more important to vaccinate as soon as possible

March 4th is International HPV Awareness Day

Experts suggest that women aged 9 to 26 should be given the HPV vaccine as a priority, especially before the age of 17 and before the first sexual intercourse to maximize the benefits; at the same time, women aged 27 to 45 who are eligible are recommended to be vaccinated with the HPV vaccine

However, as to how to choose this needle, the news on the Internet is dazzling and confusing

Bivalent vaccine can play a preventive role

Currently, the HPV vaccines approved for marketing in China include two bivalent vaccines, one quadrivalent vaccine and one ninevalent vaccine

Experts said that there are 14 high-risk HPV types that cause cervical cancer, of which the most common types are 16 and 18, which can cause about 70% of cervical cancers

"Many female friends see that HPV vaccines are divided into bivalent, quadrivalent and nine-valent, and they start to wonder which one is better to vaccinate

Vaccine protection period may exceed 10 years

Since the launch of the HPV vaccine in 2006, long-term follow-up studies have confirmed that the protective efficacy of the HPV vaccine can last up to 10 years, with a 12-year trend of protection

Xue Fengxia said, however, how long the immune protection can be maintained after the final HPV vaccine is not completely clear, and further follow-up observation and further scientific research are needed

Cervical cancer screening best before vaccination

If you have been regularly screened for cervical cancer according to the cervical cancer screening requirements before HPV vaccination, and there are no abnormal screening results, you do not need to have cervical cancer screening (including HPV testing or cervical cells) before vaccination.

"It should be noted that vaccination with HPV vaccine does not mean that you will not suffer from cervical cancer for life.
