MMR Vaccine

MMR vaccine, or the Measles, Mumps, and Rubella vaccine, protects against the three infectious diseases. MMR is a weakened live virus vaccine that helps develop immunity through active immunisation. Children between the age of 1-12 years are required to take this vaccine to effectively prevent measles, mumps, and rubella. Usually, the first dose is administered to children between 12 to 15 months of age and the second dose between 4-6 years.

Why is MMR Vaccine Given?

MMR vaccine is necessary to prevent the three diseases. Before the advent of vaccination, these diseases were common and led to fatal consequences as well. MMR is the most effective vaccine for measles.

Let's have a look at the symptoms and associated risks of measles, mumps and rubella:

• Measles

It causes high fever, cough, cold, and reddish eyes. In the worst cases it can lead to ear infections and pneumonia. MMR is a highly effective measles vaccine.

• Mumps

It leads to headache, swelling of muscles, body ache, fever and softening of salivary glands. If untreated, it can cause permanent deafness and brain swelling. Most efficacious mumps vaccine is MMR.

• Rubella

Fever, rashness and irritation in eyes is commonly experienced in Rubella. In severe cases it can cause arthritis in women. If a pregnant woman contracts rubella, she will either suffer a miscarriage or the child will be born with birth deformities. MMR is a potent rubella vaccine.

Now that you have understood the reason why MMR vaccine is given, let us understand how it functions.

How does the MMR Vaccine Work?

MMR vaccine contains a highly weakened viral strain. Once it's injected, the body detects an alien substance and the immune system is stimulated to develop a resistance against MMR. It's a highly effective vaccine that provides life-long protection against the three diseases in most cases. However, an additional dose later in life may be required if there’s an epidemic outbreak. The efficacy of the vaccine depends on the dose. Complete two doses of MMR vaccine provides more than 95% protection against measles, 85% against mumps, and over 97% against rubella.

How is MMR Vaccine Given?

According to the US' CDC (Centre for Disease Control), children should take both doses of MMR vaccine before the age of 6. The first dose is administered between the age of 12-15 months. MMR vaccine is injected as a shot like most other vaccines.
