How does it work?
This chickenpox vaccine contains a live, weakened form of the virus that causes chickenpox, varicella-zoster. It provokes the body's immune response without causing the disease.
What is it used for?
-
Vaccination against chickenpox
Warning!
- The safety of this vaccine during pregnancy has not been established and it must not be administered to pregnant women because of the unknown risk to the mother and foetus. Women who receive this vaccine should use contraceptive measures to prevent pregnancy occuring between the two vaccine doses, and for three months following the second dose.
- This vaccine may not completely protect all individuals who receive it, and does not provide full immunity against chickenpox infection until about six weeks after the second dose.
Use with caution in
- Severe skin disorders, such as severe eczema
Not to be used in
- Allergy to other varicella vaccines

Breastfeeding
- Children less than 1 year of age
- People who are or who have recently received treatment that suppresses the activity of the immune system, eg long-term oral corticosteroids, chemotherapy, radiotherapy, medicines to prevent transplant rejection

This medicine should not be used if you are allergic to one or any of its ingredients. Please inform your doctor or pharmacist if you have previously experienced such an allergy.
Pregnancy and Breastfeeding
Certain medicines should not be used during pregnancy or breastfeeding. However, other medicines may be safely used in pregnancy or breastfeeding providing the benefits to the mother outweigh the risks to the unborn baby. Always inform your doctor if you are pregnant or planning a pregnancy, before using any medicine.
- The safety of this vaccine during pregnancy has not been established and it must not be administered to pregnant women because of the unknown risk to the mother and foetus. Women who receive this vaccine should use contraceptive measures to prevent pregnancy occuring between the two vaccine doses, and for three months following the second dose.
- The infants of women who have not had chickenpox will not have acquired immunity to chickenpox from their mothers. Breastfeeding mothers should therefore not be given this vaccine, as there may be a risk of the vaccine strain of the virus being transmitted to the infant through the breast milk, causing infection.
