The said cervical injection is the cervical cancer vaccination. Cervical cancer vaccination requires indications, for example, before vaccination, if a woman is married or has a history of sexual life, she needs to have a cervical cancer screening to understand whether there are lesions on the cervical epithelium and whether she has high-risk HPV infection. If there are lesions, cervical cancer vaccination is not allowed and appropriate treatment is recommended. A total of 3 doses of cervical cancer vaccine are required, and all 3 doses should be avoided during menstruation, and should not be given during breastfeeding or pregnancy, and should be completed within 1 year, and pregnancy should be considered 6 months after completion of the vaccination. In addition, the cervical vaccination can prevent cervical cancer with a prevention rate of 90%-92%, but some people may have cervical cancer again even though they have received the cervical cancer vaccination, so they should be reviewed regularly.
