Is the nine-valent vaccine mandatory?

The nine-valent cervical cancer vaccine is clinically recommended, but not required.
Nine-valent vaccine usually refers to the nine-valent cervical cancer vaccine, which is a kind of vaccine used to prevent human papillomavirus (HPV) infection. For women aged 16 to 26 years old, especially for those who are not sexually active, it is recommended to receive the nine-valent cervical cancer vaccine so as to achieve the effect of preventing cervical cancer.
Cervical cancer vaccines include bivalent, quadrivalent, and nine-valent vaccines. For women who do not have the nine-valent cervical cancer vaccine in their local area or who are older than 26 years old, they can be vaccinated with the bivalent or quadrivalent vaccine to prevent cervical cancer. The age for both bivalent and quadrivalent cervical cancer vaccination is 9 to 45 years old. There is a crossover in the types of viruses prevented by the three vaccines, so it is sufficient to choose one of the vaccines to be injected.
Cervical cancer vaccination cannot replace cervical cytology examination. Women who are married or sexually active should undergo cervical cancer screening every year to control cervical lesions to be detected at an early level.
Breastfeeding and pregnant women are not recommended to receive cervical cancer vaccine, and when combined with other diseases, it is recommended to evaluate whether they can receive the nine-valent cervical cancer vaccine under the guidance of a doctor. For specific cases, it is recommended to consult a specialized doctor.
