Nine years of HPV protection.

How many years can the nine-valent vaccine for cervical cancer be guaranteed? Generally, it can be guaranteed for about 20 years. If it is 20 years old, you can make another injection according to your own physical condition. The applicable age of the nine-valent vaccine is 16-26 years old. Even some countries raise it earlier. When it is mentioned that it can be played at the age of 9, adults who are not infected with HPV can also be injected with nine-valent vaccine. The nine-valent vaccine, which includes two low-risk viruses 6 and 11 and seven high-risk viruses 16, 18, 33, 31, 45, 52 and 58, effectively controls infections caused by these viruses and has a cross-over effect on others, preventing 90% of cervical cancer. But even with cervical cancer vaccine, sexually active women still need regular cervical cancer screening.
