What happens if I have a fever after getting the MMR vaccine?

Vaccines are highly recommended in modern medicine because they can bring very powerful benefits to the body. They can enhance the body's resistance to certain diseases and make the body immune to diseases. However, vaccines are not omnipotent. Some vaccines may cause side effects to the body. For example, why do you have a fever after getting the measles, mumps and rubella vaccine? Let’s take a look at the explanation below.

Measles and mumps are acute respiratory infectious diseases that are easily spread among young people. People with measles and mumps are prone to complications such as pneumonia, laryngitis, myocarditis, encephalitis, orchitis, oophoritis, and pancreatitis. The measles-mumps-rubella vaccine is mainly used for young children. If an endemic epidemic occurs, it can be used by adolescents under the age of 18, but it is not necessary.

First of all, the most common adverse reaction is low-grade fever. Parents need to pay close attention to their children's temperature changes and the condition of the vaccination site. Generally speaking, if the body temperature does not exceed a low fever of 38.5℃, and general reactions such as redness, swelling, and nodules at the injection site occur, no treatment is required. Remember not to take any measures at will. Secondly, if you experience a high fever or a large nodule at the vaccination site, seek medical attention promptly and report to the vaccinating doctor. The treatment of reactions caused by different vaccines is not exactly the same. For example, hot compress can be applied to the nodules caused by vaccination with diphtheria, pertussis and tetanus vaccine, but hot compress is strictly prohibited for nodules caused by vaccination with BCG. So if you find any abnormal situation, remember not to deal with it arbitrarily.

Vaccines refer to preventive biological products used for human vaccination in order to prevent and control the occurrence and spread of infectious diseases. The fundamental purpose of vaccination is to prevent infectious diseases. Of course, some vaccines may cause adverse reactions in children, such as low fever, rash, crying due to fright, etc., but in most cases, these adverse reactions are normal and transient. Parents must not delay the normal vaccination procedure because of fear.

The national immunization program is formulated based on the characteristics of the vaccine, the developmental status of children, and the epidemic patterns of the disease. As long as the child has no contraindications to the corresponding vaccine, it is best to vaccinate the child in a timely manner to reduce the risk of infection.
