Brief summary: Recommendations concerning the administration of Zostavax® in patients with antibody deficiency are unclear. The investigators plan to assess the immunogenicity and safety of Zostavax® in patients with antibody deficiency as compared with healthy volunteers.

Detailed description: Common variable immune deficiency (CVID), specific antibody deficiency (SAD), and X-linked agammaglobulinemia (XLA) are among the most common primary antibody deficiencies in which the mainstay of treatment is gammaglobulin replacement. The use of high doses of immunoglobulin replacement therapy and the early recognition of co-morbid diseases during the course of CVID, SAD, and XLA has improved survival and led to an aging population of CVID, SAD, and XLA patients.

The Advisory Committee on Immunization Practices (ACIP) recommends routine vaccination of all persons aged \>60 years with 1 dose of vaccine directed against herpes zoster (Zostavax®) in the absence of any contraindications. Current standard of care includes avoidance of all vaccines when receiving gammaglobulin products due to passive immunity obtained from gammaglobulin against vaccine preventable infections. The exception to this rule is that patients on gammaglobulin should receive the yearly influenza vaccine due to its enhanced cell mediated immunity against the influenza virus. Clinical immunologists currently have no data upon which to advise patients receiving gammaglobulin replacement including those with CVID, SAD, and XLA concerning use of Zostavax®.

All gammaglobulin replacement products maintain protective antibody levels against VZV. However, humoral immune responses with anti-VZV antibodies are relatively constant and do not protect against the development of shingles. Varicella zoster virus specific cell mediated immunity (VZV-CMI), which is T cell dependent, is the critical component in preventing herpes zoster (shingles). VZV-CMI diminishes with age leaving the elderly most susceptible to shingles. Several studies have concluded that boosting VZV-CMI protects older adults from developing herpes zoster and postherpetic neuralgia (PHN).

Recommendations on the prevention of herpes zoster published in the Morbidity and Mortality Weekly Report (MMWR) by the Centers for disease control (CDC) in May 2008 make the following statements:

1. Zoster vaccine should not be administered to persons with primary or acquired immunodeficiency including:

   a. Persons with clinical or laboratory evidence of other unspecified cellular immunodeficiency.
2. Persons with impaired humoral immunity (e.g., hypogammaglobulinemia or dysgammaglobulinemia) can/should receive zoster vaccine.

The investigators hypothesize that vaccination with Zostavax® in adults with CVID, SAD, and XLA who have evidence of normal cell mediated immunity with normal T cell quantities and function will have a boost in VZV-CMI thereby reducing susceptibility to shingles and PHN.

Successful completion of this study will provide clinical immunologists with data upon which to advise antibody deficient patients concerning the use of Zostavax®.
