The second-order and fourth-order cervical cancer vaccines, i.e., bivalent and quadrivalent cervical cancer vaccines, have their own advantages, which mainly lie in the differences in the types of preventive viruses, applicable population and price. 1. Bivalent cervical cancer vaccine: The bivalent cervical cancer vaccine can prevent the infection of HPV16 and 18 viruses, which is two types less than the quadrivalent vaccine. The vaccination age is from 9 to 45 years old, and the price is relatively lower. 2. Cervical cancer quadrivalent vaccine: The cervical cancer quadrivalent vaccine can prevent HPV6, 11, 16 and 18 viral infections, and there are two more types of HPV6 and 11 than the bivalent vaccine, and HPV6 and 11 infections can lead to condyloma acuminatum. The quadrivalent vaccine is administered between the ages of 20 and 45, a relatively reduced age range than the bivalent vaccine, and is relatively more expensive. When patients need to vaccinate against cervical cancer, they can consult the vaccination doctor and make a comprehensive choice according to their age and economic conditions.
