Varivax (Varicella vaccine) (Varicella virus vaccine live) — Uses, Dosage, Side Effects & Safety

Drug class: Vaccine (Live, Attenuated Virus)

Overview

Varivax (Varicella vaccine) is a live, attenuated vaccine used to protect against chickenpox (varicella), a highly contagious disease caused by the varicella-zoster virus. The vaccine helps your immune system recognize and fight the virus if you are exposed in the future, significantly reducing your risk of infection or severe illness. Varivax is recommended for children, adolescents, and adults who have not had chickenpox or have not been previously vaccinated. It is usually given as a two-dose series, providing long-lasting immunity for most people. The vaccine is safe and effective, but like all vaccines, it may cause mild side effects in some individuals. Key points: Varivax cannot cause chickenpox in healthy people, but mild rash or fever may occur. It is important to complete the full vaccine series for optimal protection. Inform your healthcare provider of any immune system problems or allergies before receiving the vaccine.
