The age for girls to get the nine-valent cervical cancer vaccine is 9-45 years old. The nine-valent cervical cancer vaccine protects against infections caused by HPV (human papillomavirus) subtypes 6, 11, 16, 18, 31, 33, 45, 52 and 58. The older a woman is, the higher her risk of contracting cervical cancer, especially for those who are already sexually active, the higher their risk of exposure. It is recommended that women receive the nine-valent vaccine between the ages of 9 and 45. The vaccination schedule for the nine-valent vaccine is 0-2-6, with 0 usually referring to the time of the 1st vaccination, 2 referring to the interval of 2 months after the 1st vaccination before the 2nd vaccination, and 6 usually referring to the interval of 6 months after the 1st vaccination before the 3rd vaccination. Women can prevent cervical cancer with the 9-valent cervical cancer vaccine, but it is not 100% effective, and they still need to go to the hospital regularly for cervical cancer screening after the vaccination.
