The Varicella Vaccine is designed to protect against chickenpox, a highly contagious viral infection caused by the varicella-zoster virus. The vaccine is typically given in two doses, with the first dose administered to children between 12 and 15 months of age and the second dose between 4 and 6 years. Receiving the Varicella Vaccine significantly reduces the risk of contracting chickenpox and its potential complications, such as skin infections and pneumonia. It is also recommended for older children, adolescents, and adults who have not had chickenpox or the vaccine, ensuring broader community immunity.
