You need to avoid spicy, greasy, cold and allergenic food after getting MMR. MMR vaccine is composed of measles, mumps and rubella live attenuated viruses and is mainly used to prevent measles, rubella and mumps. Spicy foods such as onion, ginger and chili should be avoided after MMR vaccination. This is because the body will experience adverse reactions after vaccination, such as increased body temperature, redness and swelling at the injection site, pain, nausea and vomiting. If you eat spicy food, it will irritate the gastrointestinal tract and aggravate the adverse reaction. Greasy food is not easy to digest and will aggravate the burden on the gastrointestinal tract, leading to confusion with adverse reactions to vaccines. Some of the MMR vaccines are prepared by culturing chicken embryo cells. If allergy is triggered by eating eggs, the injection of this type of vaccine may aggravate the rapid-onset allergic reaction. After the injection of MMR vaccine, you must pay attention to a light and easy-to-digest diet, as well as drinking plenty of warm water and avoiding over-exertion of the body.
