There is generally no significant difference between domestic and imported of the nine-valent HPV vaccine. The nine-valent HPV vaccine can prevent a variety of HPV infections from causing warts and cervical cancer. Compared to the domestic HPV vaccine, the imported nine-valent HPV vaccine has been on the market for a longer period of time, and the vaccinated population is more extensive, but the actual preventive effect should not be too different. Patients can choose to receive the vaccine according to their age and financial situation. HPV vaccination needs to go to a designated vaccination site and be operated by professional medical personnel. Meanwhile, it should be noted that after the vaccination, regular cervical cancer screening is also required, and the vaccine cannot replace the screening.
