The HPV vaccine is not life-threatening, and no cases have been found in which HPV vaccination was life-threatening. Before receiving the HPV vaccine, routine tests are required. Both unmarried and married women can receive HPV vaccine. If you are a married woman or an unmarried woman who has sex, you need to do cervical cancer screening, and if you have cervical cancer, there is no need to receive HPV vaccine. HPV vaccine is also not suitable for patients with serious medical diseases, such as liver failure, kidney failure, and blood clotting disorders. The HPV vaccine is not effective for one dose, but three doses are needed to be effective, and it is necessary to finish three doses within the vaccine. Having received the HPV vaccine only reduces the chance of developing cervical cancer, but it does not mean that one hundred percent of people will not develop cervical cancer.
