As the incidence of cervical cancer is gradually increasing, cervical cancer vaccination is a topic of concern for women nowadays. What is the quadrivalent cervical cancer vaccine? The quadrivalent cervical cancer vaccine can prevent infection with human papillomavirus high-risk types 16 and 18; low-risk types 6 and 11. It can prevent both part of cervical cancer and part of acromegaly. The quadrivalent cervical cancer vaccine is mainly administered to women between the ages of 20 and 45, and the age range for vaccination is relatively wide. After cervical cancer vaccination, it can only prevent the corresponding type of HPV infection, but not all HPV infections. For women who are already infected with HPV, the cervical cancer vaccination does not provide prevention.
