The main reason why the rabies vaccine is not recommended during breastfeeding is due to the fact that the vaccine may have some effect on the state of breastfeeding. Vaccines are biological agents made from related viruses, bacteria, and other substances that act as a preventive agent through the body’s production of specific antibodies after injection. Although the act of breastfeeding does not affect the injection and effect of the rabies vaccine, after the vaccine is administered, the body may experience certain discomforts and special reactions, which may easily affect a woman’s breastfeeding status, and therefore the rabies vaccine is not recommended during breastfeeding. If a breastfeeding woman is at risk of contracting the rabies virus, she still needs to get the rabies vaccine in a timely manner. After receiving the rabies vaccine, breastfeeding should be stopped for about 2 days until all body functions have returned to normal before continuing to breastfeed. Breastfeeding women are advised to stay away from animals such as cats and dogs to minimize the need for rabies vaccination.
