T Cell Responses to Varicella Zoster Virus (VZV) Vaccine SLVP020
In this study the investigators are trying to identify immune signatures that are associated with effective or poor vaccine responses to naturally-acquired herpes zoster virus and the zoster (shingles) vaccine, Zostavax.
Stanford is currently not accepting patients for this trial.
Collaborator: National Institute of Allergy and Infectious Diseases (NIAID)
- Biological: Zostavax™
- Otherwise healthy adult non-twins and twin pairs, 40-49 years of age (Cross-Sectional
study) or 50 years of age and older (Vaccination study). If a volunteer cannot
participate in the Vaccination study after screening, may be considered for
- History of prior chicken pox infection or living within the continental U.S. for past
- Willing to complete the informed consent process
- Availability for follow-up for the planned duration of the study (Cross-Sectional
study: 1 visit; Vaccination study: 5 visits within 4-5 weeks)
- Acceptable medical history and vital signs
- History of shingles within 5 years of enrollment
- Prior vaccination with Zostavax vaccine for prevention of shingles
- Vaccination Study only: History of severe allergic reactions to vaccine components,
including gelatin and neomycin.
- Vaccination Study only: Life-threatening reactions to previous vaccinations.
- Vaccination Study only: Adults weighing less than 110 pounds.
- Active systemic or serious concurrent illness, including febrile illness on the day of
- History of immunodeficiency disorder
- Chronic HIV, Hepatitis B or Hepatitis C infection
- Known or suspected impairment of immunologic function, including, but not limited to
clinically significant liver disease, diabetes mellitus treated with insulin, moderate
to severe renal disease or any other chronic disorder which, in the opinion of the
investigator, might jeopardize volunteer safety or compliance with the protocol.
- Recent or current use of immunosuppressive medication, or anticipated use during study
period, including systemic corticosteroids (corticosteroid nasal sprays, inhaled
steroids and topical steroids are permissible).
- Blood pressure >150 systolic or > 95 diastolic at Visit 1
- History of chemotherapy treatment for cancer.
- Malignancy, other than squamous cell or basal cell skin cancer (includes solid tumors
such as breast cancer with recurrence in the past year and any hematologic cancer such
as leukemia or lymphoma) which, in the opinion of the investigator, might jeopardize
volunteer safety or compliance with the protocol. Prostate cancer may be acceptable if
no metastases and not undergoing treatment with immunosuppressive medications.
- Autoimmune disease, including rheumatoid arthritis, treated with immunosuppressive
medication such as Plaquenil, methotrexate, prednisone, Enbrel, which in the opinion
of the investigator, might jeopardize volunteer safety or compliance with the protocol
(thyroid disease may be acceptable).
- History of blood dyscrasias, renal disease, or hemoglobinopathies requiring regular
medical follow up or hospitalization during the preceding year
- Use of anti-coagulation medication such as Coumadin or Lovenox, or anti-platelet
agents such as aspirin (except aspirin up to 325 mg. daily), Plavix or Aggrenox which
may, in the opinion of the investigator, jeopardize volunteer safety or compliance
with the protocol.
- Receipt of blood or blood products within 6 months prior to enrollment and during the
- Use of antiviral medications within 24 hrs. prior to enrollment, and for the
Vaccination study, for the 14 days following study vaccination.
- Inactivated vaccine within 14 days prior to enrollment and during study period(avoid
non-study related immunization during the study period)
- Live, attenuated vaccine within 60 days prior to enrollment and during study period
(avoid non-study related immunization during the study period)
- Pregnant or lactating woman, planning to become pregnant (pregnancy should be avoided
for 3 months following administration of Zostavax vaccine).
- Use of investigational agents within 30 days prior to enrollment and during study
- Donation of a unit of blood within 6 weeks prior to enrollment and during study period
- Medical or psychiatric condition or occupational responsibilities that preclude
subject compliance with the protocol
- Any condition which, in the opinion of the investigator, might interfere with
volunteer safety, study objectives or the ability of the participant to understand or
comply with the study protocol.
