The MMR vaccine is an injection that prevents you from catching the following three diseases. Measles can cause ear infections, pneumonia, fits and inflammation of the brain. Sometimes it may prove fatal to life. Mumps can cause meningitis, which can cause deafness. It may cause inflammation of the pancreas, nausea and vomiting. Rubella, also called German measles, causes heart damage, blindness, deafness and brain damage. It can also lead to miscarriage.

Rubella, commonly known as German measles, is often not very dangerous and is generally found among children. It is known that children recover from this disease rather quickly than adults, and the disease typically lasts from 3-4 days. However, as harmless as this disease may be, it may become very dangerous in certain conditions.

Mumps, also identified as epidemic parotitis, is a viral syndrome that is caused by the mumps disease. In the past, it used to be a disease that was extremely widespread in children; however given that the development of the vaccines it has become extremely rare in most countries. Most third world countries, however, still have huge number of cases once a year.

In most recent years, many parents have urged that single vaccines should be administered to lookout against the three diseases: measles, mumps, and rubella. Parents are baffled in deciding between a single vaccine dosage and MMR dosage to protect their children. This is a correct fact that administering single vaccines could lessen self-confidence in the vaccination programme which could direct to reduced uptake and putting more people at peril.
