简要总结
This study is designed to determine the safety and immunogenicity of a Rift Valley Fever (RVF) Vaccine
详细描述
Study Objectives:
The objectives of this two-part, primary immunization and booster dose, study are to continue to collect safety data on Rift Valley Fever (RVF) Vaccine, Inactivated (TSI-GSD 200); and, to continue to collect immunogenicity data on Rift Valley Fever (RVF) Vaccine, Inactivated (TSI-GSD 200) and analyze interim data to determine whether a 6-month dose is indicated; and, to provide potential protection for personnel at risk for occupational exposure to the RVF virus and collect data on incidence of occupational RVF infection (subclinical and clinical) in immunized personnel.

入选标准
- •Parts A & B:
- •At least 18 years old, or if active military duty, 17 years old,
- •Females of childbearing potential must agree to have a urine pregnancy test within 48 hours before receipt of each dose of vaccine. The test results must be negative. Females will be advised not to become pregnant for 3 months after the primary series and each booster dose, and must not be breast-feeding,
- •Subject must be actively enrolled in the SIP to be vaccinated at USAMRIID or be otherwise authorized (with documentation) by the DOD
- •Subjects must be at risk for exposure to RVF virus,
- •Subjects must have an up-to-date (within 1 year) medical history, physical examination, and laboratory tests in their charts and be medically cleared for participation by an investigator. Examinations or tests may be repeated within 1 year at the discretion of the enrolling physician.
- •Volunteer must have signed and dated the approved informed consent (Volunteer Agreement Explanation and Affidavit).
- •Additional Inclusion Criteria for Part B:
- •Completion of primary series and any follow-up titer (PRNT80) < 1:40 from the current or a previous RVF IND 365 protocol.
排除标准
- •Parts A & B:
- •Clinically significant abnormal lab results including evidence of Hepatitis C, Hepatitis B or carrier state, or elevated liver function tests.
- •Personal history of immunodeficiency or current treatment with immunosuppressive medication, at the discretion of the physician.
- •Confirmed HIV infection.
- •Any medical condition that, at the discretion of the physician, may jeopardize the safety of the volunteer.
- •Any serious or life-threatening allergies to any component of the vaccine: formalin, human serum albumin, neomycin, streptomycin
- •Administration of any other vaccine within 28 days of any dose of RVF vaccine.
- •Any unresolved adverse event resulting from a previous immunization.
- •Additional Exclusion Criteria for Part B:
- •An adequate PRNT80 (≥ 1:40) after completion of primary series.
