How to define nine-price 26-year-old?

The age of nine-valent HPV vaccine injection needs to be between 16-26 years old, and 26 years old is defined as one year old. If you are over 26 years old and the effect of the nine-valent vaccine is not good, you can inject the four-valent vaccine. The tetravalent vaccine is suitable for people aged 20 to 45.

Injection of HPV vaccine can reduce the infection rate of human papillomavirus, thus greatly reducing the incidence of cervical cancer. However, there are dozens of human papillomavirus viruses, and the vaccine is only effective for this virus, but not for other types of viruses, so women also need to be screened before cervical cancer every year.
