The chickenpox vaccine is a series of two injections. It is routinely given to children at ages:
Children who have not been vaccinated and have not been exposed to chickenpox can also receive the series.
In addition, the vaccine should be given to adults who do not have immunity to chickenpox. Talk to your doctor. If you have certain conditions, you will not be able to have this vaccine.
The vaccine can also reduce your risk of infection if given within three days of exposure to chicken pox.
If you are unable to receive the varicella vaccine, you might be able to receive varicella-zoster immune globulin. Immune globulin is a blood product that contains antibodies to the chickenpox virus.
For prevention, immune globulin is given by injection immediately after exposure to the VZV virus (within 96 hours).
It is usually only given to people who are at unusually high risk for severe complications from the disease. These may include:
- Adults, including pregnant women
- Newborns whose mothers have chickenpox
- People who are immunosuppressed or very ill
If someone in your household gets chickenpox, you can prevent it from spreading by:
- Keeping them isolated until the disease runs its course and all blisters have crusted over
- Informing others who have been in recent contact with your child that they may have been exposed to chickenpox
