Generic Name: Measles-Mumps-Rubella vaccine live
Product Name: Priorix


Priorix is used to prevent measles, mumps and rubella (German measles). The vaccine is sometimes called MMR vaccine.


Priorix works by causing the body to produce its own protection (antibodies) against measles, mumps and rubella which are all infectious diseases caused by viruses.

Dose advice

Dose information

How Priorix is given

Priorix comes as a powder which is mixed with sterile water before it is injected under the skin (subcutaneously) or into upper leg muscle for babies under 12 months or into the upper arm muscle for babies over 12 months, older children and adults. Priorix should never be given into a vein.

Some people can feel dizzy or lightheaded after the vaccine is given. This can affect your ability to drive or operate any machinery. Do not drive or use machines after you have been given Priorix unless you are sure you are not affected.

It is recommended that you remain in the clinic for approximately 15 mins after receiving the injection as there is a risk of allergic reactions occurring and this can include rashes that may be itchy or blistering, swelling of the eyes and face, difficulty in breathing or swallowing, a sudden drop in blood pressure and loss of consciousness.


Priorix is generally given as a single 0.5mL dose. The same dose is used for children and adults.

The first dose of Priorix is generally given to children at 12 months of age. A second dose is then administered to children at 4-6 years of age; preferably before commencement at school. If your child misses a scheduled dose, talk to your doctor or nurse and arrange another visit as soon as possible.

If you have any questions about Priorix, ask your doctor.
