What is HPV?
Human Papillomavirus (HPV) is a very common virus primarily transmitted through sexual contact. Most HPV infections clear on their own, but persistent infection with certain high-risk types (such as HPV 16 and 18) is the main cause of cervical cancer.
The Importance of the HPV Vaccine
Vaccination is the most effective primary prevention measure against cervical cancer. The vaccine effectively prevents persistent infections and related precancerous lesions caused by high-risk HPV types, significantly reducing the risk of developing cervical cancer. The World Health Organization (WHO) recommends including HPV vaccination in national immunization programs.
Who Should Get Vaccinated and When?
The HPV vaccine is most effective when administered before the first sexual activity. The main recommended groups include:
- Girls aged 9-14: The primary target group for vaccination.
- Women aged 15-45: Even if sexually active or previously infected with HPV, vaccination can still protect against HPV types not yet encountered.
- Men: Vaccination can prevent HPV-related diseases such as anal and oropharyngeal cancers and reduce virus transmission.
Please follow the recommendations of local health authorities and the vaccine instructions for specific age groups and schedules.
Is Cervical Cancer Screening Still Needed After Vaccination?
Yes. The vaccine does not protect against all high-risk HPV types and cannot treat existing infections. Therefore, regular cervical cancer screening (such as TCT or HPV testing) remains crucial for the early detection and management of precancerous changes. Combining vaccination with regular screening provides dual protection for women's health.
How to Get the HPV Vaccine in China?
Several HPV vaccines are currently available in China, including bivalent, quadrivalent, and nonavalent vaccines. Some cities have included HPV vaccination in free immunization programs for school-aged girls. It is recommended to consult your local community health service center, Center for Disease Control and Prevention (CDC), or authorized medical institutions for information on vaccine availability, local vaccination policies, and appointment procedures.
