The exact duration of effectiveness of the HPV vaccine has not been conclusively determined. Available data suggests that it is around 10 years, and it is recommended that women should still be retested on a regular basis after vaccination. Long-term persistent infection of HPV (human papillomavirus) is closely associated with the development of cervical cancer in women, and it is currently recommended that women receive the HPV vaccine in order to reduce the chances of infection. Current data suggests that the protective effect of the HPV vaccine lasts for more than 10 years after three doses, but there is no definitive conclusion on how long it lasts, and the effect of the vaccine can vary among different populations. Therefore, regardless of whether or not you have received the HPV vaccine, it is recommended that you go to the hospital on a regular basis for HPV testing, cervical cytology, etc. to rule out cervical lesions. If necessary, please seek timely medical treatment, consult a specialized doctor and standardize the diagnosis and treatment.
