How long it takes to finish the cervical cancer vaccine depends on the type of cervical cancer vaccine that the patient chooses. Currently, there are three types of cervical cancer vaccines, namely bivalent vaccine, quadrivalent vaccine and nine-valent vaccine. The cervical cancer bivalent vaccine is administered as the second and third doses in the first and sixth months after the first dose, respectively. The cervical cancer quadrivalent and cervical cancer nine-valent vaccines are administered in the same way, with the second and third doses administered in the second and sixth months, respectively, after the first day of injection. It is recommended that all three doses of the cervical cancer vaccine be completed within one year. The antibodies produced by the cervical cancer vaccine in a woman’s body are related to the type of injection, so it is best to complete all three doses on time so that the antibodies formed will be more effective.
