Do you need to have eaten a whole egg before getting the measles, mumps, and rubella (MMR) vaccine?
The MMR (measles, mumps, and rubella) vaccine can be administered as long as the baby is in good health and does not have a cold or fever.
If the baby is allergic to eggs, it's best to temporarily delay the MMR vaccination to avoid worsening symptoms. Measles, part of the MMR combination, is caused by the measles virus and commonly presents with symptoms such as oral mucosal spots, conjunctivitis, and fever. Mumps, another component, causes swelling of the salivary glands and occurs when the virus invades the central nervous system; severe cases may lead to meningitis, requiring prompt medical treatment under a doctor’s guidance, such as oral administration of ribavirin tablets or ibuprofen capsules. The MMR vaccine effectively prevents three diseases—rubella, measles, and mumps—with a single shot. However, if the baby has a weakened immune system or is currently experiencing fever, vaccination should usually be postponed. Once administered, the vaccine helps reduce the replication of the measles virus in the body and provides preventive protection.
In addition, after receiving the MMR vaccine, it's important to closely monitor the baby’s physical condition, and bathing should be avoided within 24 hours.
