What is MMR vaccine?MMR vaccine is used to help prevent serious, sometimes fatal, infections caused by 3 viruses: measles (also known as rubeola), mumps, and rubella (also known as German measles). These are common childhood infections that may cause severe problems (such as deafness, lung/brain problems, or harm to an unborn baby). Therefore, preventing these infections through vaccination is very important. This vaccine contains live viruses that have been weakened. It works by causing the body to produce its own protection (antibodies) against the viruses that cause measles, mumps, and rubella. MMR vaccine is given subcutaneous over the thigh or over the arm.
MMR vaccine Immunization schedule
- 9 months – Measles
- 12-15 months – MMR-1
- 5 years – MMR-2
EffectivenessIt is very long lasting. Everyone (more than 99%) will be protected against measles and rubella for more than 20 years after two doses of MMR. Protection against mumps after two doses of MMR is a little lower (90-95%) and appears to gradually decline. Consult doctor if you experience any symptoms.
