Varicella virus vaccine is an immunizing agent that is used to prevent infection caused by the varicella-zoster virus (VZV). The vaccine works by causing your body to produce its own protection (antibodies) against the virus.
Varicella (commonly known as chickenpox) is an infection that is easily spread from one person to another. Chickenpox is usually a mild infection but sometimes it can cause serious problems, such as pneumonia, inflammation of the brain, and a rare disease called Reye's syndrome.
Immunization against chickenpox is recommended for anyone 12 months of age and older who has not had chickenpox. Immunization against chickenpox is not recommended for infants younger than 12 months of age.
You can be considered to be immune to chickenpox only if you have received the right number of varicella vaccine doses (1 dose if you are between 12 months and 12 years of age; or 2 doses if you are 13 years of age or older). You also are considered to be immune if you have a doctor's diagnosis of a previous chickenpox infection or if you have had a blood test showing that you are immune to varicella.
Varicella virus vaccine (Zostavax®) is also used for the prevention of herpes zoster (commonly known as shingles) in people 60 years of age and older.
This vaccine is to be administered only by or under the supervision of your doctor or other authorized healthcare professional.
In deciding to use a vaccine, the risks of taking the vaccine must be weighed against the good it will do. This is a decision you and your doctor will make. For this vaccine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to varicella virus vaccine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
