The second dose of bivalent vaccine is overdue and still needs to be given, but try to catch up on it within a month.
The bivalent vaccine is a cervical cancer vaccine that primarily prevents cervical cancer caused by HPV16 and HPV18 infections. Cervical cancer is a disease caused by persistent infection of the female genital tract by high-risk human papillomavirus. HPV 16 and HPV 18 are the most common high-risk HPV types in cervical cancer.
The bivalent vaccine requires a total of three injections, with the second injection given at a one-month interval after the first injection and the third injection given at a six-month interval. The second injection of the bivalent vaccine is given more than one month later at the latest, but it is recommended that the vaccination be given at the prescribed time as much as possible, so that the effect is also less affected.
It is recommended that patients receive the vaccine in a timely manner and under the guidance of a doctor, so as not to reduce the effect of the vaccine.
