zoster vaccine (live, weakened)
How does this medication work? What will it do for me?
This medication belongs to a family of medications known as vaccines. It is used to prevent shingles for people over 50 years of age. Shingles is caused by the same virus that causes chickenpox. After a bout of chickenpox, the virus retreats to the nerves, where it lies dormant for years.
Shingles occurs when the virus becomes active again, causing a blistering rash and severe burning pain. The medication works by boosting the immune system to help prevent shingles. It does not treat shingles.
