Zoster Vaccine Live (ZVL)
The Zoster Vaccine Live (ZVL), also known as Zostavax, is a vaccine that helps prevent shingles, a painful rash caused by the reactivation of the chickenpox virus in older adults. It contains weakened live virus to stimulate your immune system to recognize and fight the virus if it reactivates. Typically recommended for people age 50 and older, the vaccine reduces the risk of shingles and its complications, such as nerve pain. While it doesn't guarantee complete protection, it significantly lowers the chances and severity of shingles episodes.
