A rash from the MMR vaccine usually goes away in 2 to 7 days, but it may take longer if it is accompanied by a viral infection or other allergic condition.
The MMR vaccine is mandatory for infants and young children, a vaccine that protects against measles, mumps, and rubella. Most people receive the MMR vaccine without significant discomfort, while a small number of people may experience fever, rash, and other discomforts after the vaccination.
A few babies will have rashes on the face or neck after MMR vaccination, which can usually subside on their own in 2-7 days without special treatment, if the rashes don’t subside or the high fever doesn’t go away, you need to consult a doctor in time.
After the injection, you need to pay attention to the hygiene of the injection site, avoid scratching or friction with clothing, and avoid spicy and stimulating diet.
