Mmr Vaccine
The MMR vaccine is a life-saving immunization that protects against three deadly diseases: measles, mumps, and rubella. The vaccine is highly effective, but it’s not perfect. A small number of people who get the MMR vaccine will still get sick with one or more of these diseases. But the chances of getting sick are much lower than if you don’t get vaccinated.
The MMR vaccine is made from live viruses that have been weakened so they can’t cause serious disease. The body recognizes these weakened viruses as “foreign” and makes antibodies to fight them off. This process helps ensure immunity (protection) against future infection with the actual disease-causing viruses. It usually takes two doses of the MMR vaccine for full protection against all three diseases. The first dose is given at 12–15 months of age, and the second dose is given at 4–6 years of age. Children who receive their first dose after their fourth birthday should get two doses, spaced four weeks apart. Adults who were never vaccinated or only partially vaccinated should also get two doses, spaced four weeks apart. There are very few side effects from the MMR vaccine—most people experience only mild discomfort such as redness or swelling at the injection site, fever, or a rash . These side effects are normal and go away on their own within a few days . Serious allergic reactions to the MMR vaccine are extremely rare , occurring in less than 1 out
