The cervical cancer vaccine is a lifelong immunity, meaning that after receiving the vaccine, the body will carry antibodies to the HPV viruses for life and will therefore remain immune to these viruses. However, since the cervical cancer vaccine does not protect against all HPV viruses, it is possible to get infected with rare HPV subtypes after vaccination. For example, women who receive the bivalent cervical cancer vaccine will not be infected with HPV 16 and 18 for life, but may be infected with HPV 6, 11, and 52 subtypes. Therefore, it does not mean that 100% of women will not be infected with HPV after vaccination, and there is no guarantee that they will not get cervical cancer. The main cause of cervical cancer is HPV 16 and 18, but other HPV types can also cause cervical cancer, and a very small number of women can get cervical cancer even when they do not have HPV infection.
