For the timing of the HPV vaccination, you can choose your own time for the first dose, but you should avoid menstruation and avoid breastfeeding. If you have a cold or fever, you cannot get the HPV vaccine either. The second shot can be given about 3 months after the first shot, and the third shot can be given within about 8 months after the second shot, which is the specific timing of the HPV vaccination. After the vaccination, you have to stay in the hospital for an hour each time for observation, and you can leave the hospital only when there is no discomfort. In addition, the HPV vaccine will only have a preventive effect when all three doses are completed, and the preventive effect cannot reach 100% in clinical practice, so it is recommended to have regular cervical cancer screening after the vaccination.
