Varicella or chickenpox is a highly contagious disease caused by the varicella-zoster virus. While chickenpox is usually a mild disease in healthy children, life-threatening complications such as pneumonia or inflammation of the brain (encephalitis) are possible. It can be fatal in about three in 100,000 cases. If a pregnant woman has chickenpox there is also a small chance of damage to the unborn baby. Chickenpox can also develop into shingles (herpes zoster) in later life.
Chickenpox is spread through coughing, sneezing and direct contact with chickenpox blisters.
The disease starts with cold-like symptoms such as a mild fever, followed by a rash that turns into red spots and blisters.
Yes. The safest and most effective way of preventing chickenpox is through vaccination. Varicella vaccination provides long lasting protection for children. One dose is required for children under 14 years of age. No booster doses are required.
If your child has already had chickenpox, they are immune to the disease and do not need to be vaccinated.
The chickenpox vaccine contains weakened varicella-zoster virus, amino acids for injection, human albumin, lactose, neomycin sulphate and polyalcohols. Possible side effects include discomfort, redness and swelling at the injection site.
Rarely, a mild chickenpox-like rash may develop at the injection site or on the body. If this occurs, the rash usually appears about eight days after vaccination (but can appear any time between five to 26 days). Students with this rash should avoid contact with people with weakened immune systems. More serious side effects are extremely rare.
Students aged 14 years or older require two injections, given one to two months apart. Fourteen year old students who receive their first vaccine as part of the School Based Vaccination Program are eligible to receive their second free vaccine from their doctor or local service provider while still in Year 8. Be aware there may be a consultation fee if you take your child to your doctor.
If you plan to take your child to your doctor, it is suggested you advise the practice reception what vaccination you need when you call for an appointment. This allows the practice time to order vaccine if required.
