Getting the nine-valent vaccine does not stop you from getting your period for a year. The nine-valent vaccine is generally referred to as the nine-valent human papillomavirus vaccine, which is mainly used to prevent nine high-risk types of human papillomavirus infection, thus helping to reduce the incidence of cervical cancer. Generally speaking, after receiving the nine-valent cervical cancer vaccine, women will not experience any special discomfort and it will not affect the hormone level changes in the body, so it will not affect menstruation in general. However, a very few women may experience adverse reactions such as itching, rash and fever after receiving the vaccine. Therefore, after a woman has received the vaccine, it will not cause her not to have menstruation for one year. If women have any special uncomfortable symptoms after receiving the cervical cancer vaccine, they must consult a doctor as soon as possible and take active treatment, so as to avoid delaying the condition.
