Before receiving the cervical cancer vaccine, it is important to understand the following: First, women with a history of sexual intercourse are advised to receive the cervical cancer vaccine only if there are no positive results after clinical screening for cervical cancer. Secondly, cervical cancer vaccine is divided into bivalent vaccine, quadrivalent vaccine and nine-valent vaccine, and different vaccines should be given according to your own situation. Thirdly, cervical cancer vaccine should not be given when you have a cold or fever, or when you are menstruating. In addition, the vaccine should not be given during breastfeeding and pregnancy, and pregnancy should not be considered until about one year after the cervical cancer vaccine has been given, because after all, the cervical cancer vaccine has a certain degree of toxicity.
