Varicella Vaccine Dosage: An Introduction
There is only one standard dose for the
varicella vaccine (
Varivax®), although the vaccination schedule may vary, depending on the age of the individual at the first dosing.
Preferred Varicella Vaccine Schedule
The ideal varicella vaccine dose is 0.5 mL injected subcutaneously (under the skin) twice, once between 12 and 15 months of age and once between 4 and 6 years of age. The second dosage can be given sooner if desired (but no sooner than three months after the first dosage).
Although the previously described schedule is preferred, the same dosage (0.5 mL injected twice with at least three months between doses) is also recommended for all children between the ages of 12 months and 12 years.
Varicella Vaccine Schedule for Older Individuals
For individuals ages 13 years and older, the standard dosage of varicella vaccine is 0.5 mL injected subcutaneously twice (with at least four weeks in between doses). It is important to get the second dose, even if it is has been a very long time since the first one.
General Dosing Information
Some considerations for people getting the varicella vaccine include the following:
- This vaccine is given as two separate dosages, given at least one to three months apart (depending on the age of the individual).
- The varicella vaccine is given subcutaneously (just under the skin) on the upper arm.
- Individuals can be vaccinated if they have a minor illness, such as the common cold. However, the vaccine should be postponed if the individual is moderately or severely ill.
- If you are unsure about anything related to your dosage or varicella vaccine dosing in general, please talk with your doctor, nurse, or pharmacist.
