• Generic Name: zoster vaccine, inactivated
• Dosage Forms: n.a.
• Other Brand Names: Shingrix

Herpes zoster is caused by the same virus (varicella) that causes chickenpox in children. When this virus becomes active again, it can cause herpes zoster, or shingles. Inactivated zoster vaccine helps prevent shingles.

This vaccine works by exposing you to a small dose of inactive virus, which causes the body to develop immunity to the disease. This vaccine will not treat an active infection that has already developed in the body.

Inactivated zoster vaccine is used to prevent herpes zoster virus (shingles) in people age 50 and older, including people who previously received a live zoster vaccine (Zostavax).

Inactivated zoster vaccine will not treat chickenpox, shingles, or nerve pain caused by shingles (post-herpetic neuralgia).

Inactivated zoster vaccine may also be used for purposes not listed in this medication guide.
