About this vaccine
The MMR vaccine protects against three viral infections (measles, mumps and rubella) in one injection. Two doses give strong, long-lasting protection. Because measles is among the most contagious infections known, getting both doses on time is one of the most important steps in a child's vaccination schedule.

Ages follow the schedules listed above. Your pediatrician may adjust timing for your child.
How it's given
Injection, usually in the upper arm or thigh. This vaccine covers multiple infections in a single dose, reducing the number of separate injections needed at each visit.
Side effects & safety
A mild fever or faint rash may appear 7 to 10 days after the shot. This is a normal immune response, not infection. A small lump at the injection site is also common and resolves on its own.
A mild fever or fussiness is fairly common for a day or two. This is a sign the immune system is responding normally.
When to call your doctor: if fever exceeds 40°C, lasts more than 2 days, or your child seems unusually unwell.
