What is the varivax shot?

The Varivax shot is a vaccine that protects against varicella, the virus that causes chickenpox. It is a live attenuated vaccine, meaning it contains a weakened form of the virus to stimulate the immune system without causing the disease. Typically administered in childhood, it helps prevent chickenpox and its potential complications, such as infections or hospitalization. The vaccine is usually given in two doses, with the first dose recommended between 12 to 15 months of age and the second between 4 to 6 years.
