The 9-valent cervical cancer vaccine can be given to healthy women aged 9-45 years old, with 3 injections, 2 months after the first injection and 6 months after the third injection. 9-valent vaccine is the one that covers the most viruses, and the more viruses covered, the better the effect. After cervical cancer vaccination, it does not mean that you will not get cervical cancer, but the probability of getting cervical cancer is greatly reduced, so you should have regular cervical cancer screening.
