It is possible to have wind after MMR, and there is no scientific basis for the claim that you can’t see the wind after MMR. MMR vaccine can stimulate the body to produce immunity against measles virus, mumps virus and rubella virus at the same time, and can be used to prevent measles, rubella and mumps. After MMR vaccination, some children may have a transient fever after MMR vaccination, and some children may have a rash or pain, which usually goes away on its own without special treatment. There is no such thing as not being able to blow in the wind after MMR vaccination, but you should pay attention to keep warm and avoid blowing in the wind to avoid catching cold and causing colds and other diseases. At the same time, after vaccination, you should pay attention to the skin care of the injection site, keep the local clean to prevent infection of the vaccination site. If the fever lasts longer, the symptoms are more serious or the child’s mental state is poor after the MMR vaccination, you need to go to the hospital in time to seek medical treatment.
