Overview
The MMR vaccine is a combined immunisation that protects against three serious viral diseases: measles, mumps, and rubella. It is administered in two doses, typically given to children at 12-15 months and a second dose at 4-6 years of age. This vaccine is highly effective, with one dose providing about 93% immunity to measles, 78% to mumps, and 97% to rubella. The second dose increases immunity to approximately 97% for measles and 88% for mumps.
The MMR vaccine works by stimulating the immune system to produce antibodies against these viruses, without causing the diseases themselves. This prepares the body to fight off the viruses if exposed in the future. High vaccination coverage is crucial to maintaining herd immunity, which helps protect those who cannot be vaccinated, such as newborn infants or individuals with certain medical conditions.
The vaccine is generally safe, with most side effects being mild and temporary, such as a fever or mild rash. Serious side effects are rare. Details of the MMR vaccine in Australia can be found via the Department of Health website.
