HPV9-valent vaccine is generally used for women aged 16-26. Generally, it needs to be vaccinated three times, once in the 0 th month, 2 nd month and 6 th month respectively. Nine-valent HPV vaccine can prevent nine kinds of human papillomavirus infection, and for bivalent HPV vaccine and tetravalent HPV vaccine, the scope of preventing human papillomavirus infection is wider. HPV9-valent vaccine can not only prevent cervical cancer, but also prevent condyloma acuminatum caused by various human papillomavirus infections, such as vulva, vagina and perianal condyloma acuminatum. Therefore, if women are vaccinated with human papillomavirus vaccine, 9-valent HPV vaccine can be considered. If they can get 9-valent HPV vaccine, they should get 9-valent HPV vaccine as much as possible.
