Measles, mumps, rubella, varicella (chickenpox) – immunisation

Why is immunisation against measles, mumps, rubella and varicella important?

Immunisation against measles, mumps, rubella, and chickenpox (varicella) is one of the most effective ways to protect children and the wider community from serious infectious diseases.

Measles is a highly contagious viral disease that causes fever, cough, runny nose, red eyes and a widespread red, blotchy rash. It can lead to serious complications such as pneumonia, blindness, bleeding (thrombocytopenia), encephalitis (brain inflammation), and even death.

Mumps is a viral illness that causes fever, headache, muscle aches, tiredness, and painful swelling of the salivary glands in the jaw area. Complications can include meningitis, encephalitis, leading to deafness, and swelling of the testicles (balls) in males, rarely causing infertility.

Rubella is usually a mild illness with fever, skin rash, and swollen lymph nodes. However, if contracted during pregnancy, it can cause serious birth defects such as deafness, blindness or brain damage.

Varicella (chickenpox) is a highly contagious disease that causes an itchy rash, fever, and tiredness. The rash usually begins as small lumps that turn into blisters and then scabs. Varicella can lead to skin infections, pneumonia, and, later in life, shingles.

The MMRV (measles, mumps, rubella and varicella) vaccine offers combined protection in a single dose, making it easier to ensure children are covered against all four diseases.

Immunisation with the MMRV vaccine

The MMRV vaccine is free under the National Immunisation Program (NIP) Schedule for children at 18 months. This is their second dose for measles, mumps and rubella, and their first dose for chickenpox (varicella).

The MMRV vaccine is not recommended as the first dose of MMR (measles, mumps, rubella) vaccine in children under 4 years old because it slightly increases the risk of fever-related seizures (febrile convulsions).

It is free for young people up to 14 years who missed their childhood dose.

The MMRV combination vaccine is not recommended for people aged 14 years and over. Catch up immunisation for people aged 14 years and over is available using the MMR combination vaccine and a separate chickenpox vaccine.

People who should not be immunised with the MMRV vaccine

A child with an impaired immune system should not be vaccinated.

Some of the possible causes of impaired immunity include:

• infection with human immunodeficiency virus (HIV) or the presence of acquired immunodeficiency syndrome (AIDS) from an HIV infection
• taking certain medications, such as high-dose corticosteroids
• receiving immunosuppressive treatment, including chemotherapy and radiotherapy
• having some types of cancer, such as Hodgkin's disease or leukaemia
• having an immune deficiency with extremely low levels of antibodies (hypogammaglobulinaemia, multiple myeloma or chronic lymphoblastic leukaemia).

If your child has an impaired immune system, speak with your doctor about what options might be available.

Pre-immunisation checklist

Before receiving the vaccine, it is important that you tell your immunisation provider if your child or adolescent:

• is unwell (have a temperature over 38.5 ˚C)
• has allergies to any medicines or substances
• has had a serious reaction to any vaccine or vaccine component
• has a disease or taking medication that causes low immunity
• has received another vaccine within the last month or if they will have another vaccine within one month of the chickenpox immunisation
• has received a blood or plasma transfusion or immunoglobulins within the last 3 to 11 months or will need to receive them within 3 weeks of the chickenpox immunisation
• is pregnant

Side effects from the MMRV vaccine

The MMRV vaccine contain a very weakened form of viruses. The vaccine works by causing the body to produce its own antibodies to protect against the virus.

Most side effects from MMRV are mild and temporary. They usually occur 7 to 10 days and only last 1 to 2 days.

• Fever (may exceed 39.4°C)
• Mild rash
• Runny nose, cough, puffy eyes
• Tiredness or drowsiness
• Swelling of salivary glands
• Redness, swelling or pain at the injection site

The MMRV vaccine can cause a mild chickenpox-like rash 5 to 26 days after vaccination.

To manage side effects:

• Offer extra fluids to drink
• Do not overdress if feverish
• Use paracetamol if needed (check the correct dose)
• Apply a cool wet cloth to manage injection site discomfort

Concerns about side effects

If the side effect following immunisation is unexpected, persistent, or severe or if you are worried your child’s condition after a vaccination, see your doctor or immunisation provider as soon as possible or go directly to a hospital.

Unexpected or severe immunisation side effects may be reported to Victoria’s vaccine safety surveillance service.

Rare side effects

Uncommon or rare side effects of the MMR and MMRV vaccines include:

• fever causing seizure (febrile convulsions) – (1 in 3,000 children)
• temporary pain and stiffness in the joints – (more common in young adolescents)
• temporary low platelet count, causing bleeding or bruising

There is a very small risk of a serious allergic reaction (anaphylaxis) to any vaccine, occurring in less than one out of a million vaccinations. This is why you are advised to stay at the immunisation clinic or health service for at least 15 minutes following immunisation in case further treatment is required.

Can measles-containing vaccines cause autism?

No, vaccines do not cause autism. This has been confirmed by many large-scale, high-quality studies involving over a million children worldwide. For more information, see

Can I get my child separate vaccines for measles, mumps, rubella, and varicella?

The MMRV combination vaccine is safe and protects against all four diseases with fewer shots.

Separate vaccines are available for chickenpox (varicella), and the combination measles-mumps- rubella (MMR) vaccine.
