The difference between one shot and three shots of cervical cancer vaccine

Whether it is a bivalent, quadrivalent or nine-valent cervical cancer vaccine, the difference between one shot and three shots is mainly the different preventive functions. One shot is usually not as good as three shots in terms of preventive function. It is recommended that women continue to get the second and third shots of the cervical cancer vaccine to protect themselves as much as possible.

After one shot, the antibody level in the body is low and often cannot effectively prevent HPV infection. The chance of HPV infection is still relatively high, and the chance of cervical cancer is also relatively high. After three shots of the vaccine, the antibody level in the body is relatively high, which can effectively prevent several dangerous and common HPV infections and help avoid most cervical cancers.

No matter how many times you have received the cervical cancer vaccine, or how many valent cervical cancer vaccines you have received, as long as you have sexual activity, you should do regular cervical cancer screening and pay attention to sexual hygiene, avoid multiple sexual partners and unclean sexual life. Even if you have received three doses of cervical cancer vaccine, there is still a chance of infection with other high-risk HPVs and the possibility of developing cervical cancer.
