Chickenpox (Varicella) Vaccine

Chickenpox vaccine not only protects people who are vaccinated, but also reduces the risk in the community for people who can't be vaccinated. Some people, including those who may be at greater risk for serious disease, can't be vaccinated because of illness, medical conditions, or age. While no vaccine is 100 percent effective in preventing disease, the varicella vaccine is very successful. About 90 percent of people who are vaccinated are completely protected from chickenpox.

In addition, the vaccine almost always prevents severe disease. If a vaccinated person gets chickenpox, it's usually a very mild case lasting only a few days and involving fewer skin lesions (usually less than 50), low-grade or no fever, and few other symptoms.
