Chickenpox (varicella) and shingles (herpes zoster) are caused by the varicella-zoster virus; chickenpox is the acute invasive phase of the virus, and shingles represents reactivation of the latent phase. For information about the chickenpox vaccine, see varicella vaccine.

Indications for Herpes Zoster Vaccine
The zoster vaccine is a routine adult vaccination (The zoster vaccine is a routine adult vaccination (1). Indications for the zoster vaccine include the following:
Adults ≥ 50 years whether they have had episodes of herpes zoster or been given the previously available live-attenuated zoster vaccine or not
Adults ≥ 19 years who are or will be immunodeficient or immunosuppressed because of disease or therapy
Serologic evidence of prior varicella infections is not necessary for zoster vaccination. However, if serologic evidence becomes available and indicates no previous varicella infection, health care professionals should follow ACIP guidelines for varicella vaccination. Recombinant zoster vaccine is not indicated for the prevention of varicella, and there are limited data on use in people without a history of varicella.
