There are currently three types of cervical cancer vaccines on the market, including the bivalent vaccine, quadrivalent vaccine, and nine-valent vaccine. The bivalent vaccine mainly prevents HPV type 16 and HPV type 18 infections. The quadrivalent vaccine, in addition to the bivalent vaccine, can also prevent HPV6 and HPV11 infections. The nine-valent vaccine can prevent HPV31, HPV33, HPV45, HPV52 and HPV58 infection on top of the quadrivalent vaccine, which is the main clinical difference between the three cervical cancer vaccines. The main cause of cervical cancer infection in Asian women is the infection of HPV type 16 and HPV type 18. It is recommended to clinically combine different vaccines with your situation.
