The chickenpox vaccine helps to protect you against the chickenpox (varicella). Chickenpox can cause fever, irritability, fluid filled blisters on the skin numbering from 200 to 500, meningitis, bacterial skin infection and complications in the baby if a woman has chickenpox during pregnancy.
The vaccine contains a small amount of the live virus.
Some people may not be able to receive a live vaccine for medical reasons, please discuss with your doctor or immunisation provider for further information.
Chickenpox vaccine also comes in a combination form called measles, mumps, rubella and varicella (MMRV) combination.
The chickenpox vaccine is also recommended if you are not vaccinated or have not been medically diagnosed with chickenpox and you are:
- in contact with others with an impaired immunity, for example on chemotherapy
- have or work with young children
- planning to get pregnant
- in a high risk occupation.
How the vaccine is given
Chickenpox vaccine is given as an injection into the top of the arm.
Possible side effects
Like any medications, the chickenpox vaccine can have some minor and short lasting side effects.
Common side effects may include:
- fever – may be greater than 39 degrees Celsius in children
- pain, redness and swelling where you were immunised
- a rash of two to five fluid filled blisters at the injection occurring five to 26 days after the vaccination. This rash may also cover other areas of the body. If the rash occurs, it should last for less than one week.
Uncommon side effects may include a rash of two to five fluid filled blisters at the injection occurring five to 26 days after the vaccination. This rash may also cover other areas of the body. If the rash occurs, it should last for less than one week.
