MMR refers to the three diseases of measles, mumps, and rubella, and you can go out with the MMR shot. After the MMR vaccination, you need to stay in the room for thirty minutes, and if no adverse reaction occurs, you can usually go out. However, at this time, the immunity of the vaccinated person is low, so they should take measures to keep warm and protect themselves from the wind and the sun when they go out. Try to do outdoor activities in good weather and suitable temperature, and avoid entering crowded places to prevent infection. If there is a rash, redness or swelling at the injection site or adverse symptoms such as low-grade fever, runny nose and pain, it is best not to go out in order to avoid aggravating the discomfort by catching wind and cold. Within 24 hours after the leprosy vaccination, keep the injection site dry and clean, and try to avoid eating foods containing heterogeneous proteins such as fish, shrimp and eggs within three days, so as not to cause allergic reactions in the vaccinated person.
