Pregnancy is possible three months after the cervical cancer vaccine. The cervical cancer vaccine, which is a vaccine to prevent HPV infection in women’s body, may cause allergic reactions such as local hard nodules, itching and increased body temperature in a small number of women after the vaccination, and there is also a certain period of time for antibodies to appear in the body after the vaccination, and women’s body may become uncomfortable. If a woman becomes pregnant too early, it may affect the growth and development of the embryo in the early stage and is not conducive to the recovery of the woman’s body. It is better for women to adjust their body to a healthy state three months after vaccination, to live a regular life, to avoid the stimulation of alcohol and tobacco, to eat a reasonable diet, to be nutritious, to exercise properly, and to strengthen their physical condition before pregnancy, which is conducive to the growth and development of the fetus after pregnancy.
