What is the MMR vaccine?

Under normal circumstances, the MMR vaccine is a combined vaccine, officially known as Measles, Mumps and Rubella (MMR) attenuated live vaccine, primarily used to prevent the three acute respiratory infectious diseases: measles, mumps, and rubella. If discomfort symptoms occur, timely medical consultation is recommended for standardized treatment under a doctor's guidance. Detailed analysis is as follows:

The MMR vaccine is typically administered in two doses: the first dose at 8 months of age and the second dose between 18 to 24 months. It is important for preventing measles, rubella, and mumps. Measles is a highly contagious disease that may lead to severe complications such as encephalitis and pneumonia. Although rubella usually presents with mild symptoms, maternal infection during pregnancy can result in congenital rubella syndrome in the fetus. In addition to parotid gland swelling, mumps may also cause complications such as orchitis and oophoritis.

After receiving the MMR vaccine, mild adverse reactions may occur, such as redness, swelling, and pain at the injection site, fever, rash, and swollen lymph nodes. These reactions are generally transient and resolve spontaneously over time. However, the MMR vaccine is not recommended for individuals allergic to any of its components, those with acute illness, severe chronic diseases, those experiencing an acute exacerbation of chronic illness, those with fever, pregnant women, individuals with immunodeficiency or compromised immune function, and those with encephalopathy, uncontrolled epilepsy, or other progressive neurological disorders.

During vaccination, strict adherence to the recommended immunization procedures and precautions is essential to ensure safety and effectiveness.
