Safety: The frequency of adverse events in this RVF vaccine study will be evaluated for all intent-to-treat subjects; Immunogenicity: Measurement is the 80% plaque-reduction neutralization titer (PRNT80). [ Time Frame: AEs: recorded through day 28 after each dose; SAEs: duration of study; Immunogenicity: PRNT80 at 28 days after dose 3. Part B: Pre-6-month dose and 12 month titer. Any RVF illness in a vaccinated subject will be recorded for duration of study. ] [ Designated as safety issue: No ]

Safety and Immunogenicity Study of Rift Valley Fever Vaccine
Parts A&B: Evaluation of the Safety and Immunogenicity of Rift Valley Fever Vaccine, Inactivated, Dried (TSI-GSD 200), A Phase 2 Study

This study is designed to determine the safety and immunogenicity of a Rift Valley Fever (RVF) Vaccine

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.

Phase 2
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Prevention
Rift Valley Fever
Biological: Inactivated, Dried (TSI-GSD 200), RVF Vaccine
Part A: RVF vaccine will be given as three 1.0-ml subcutaneous primary series injections, with doses on day 0, once on days 7-14, once on days 28-42 (the third dose will be given at least 21 days after the second dose).Part B: Subcutaneous 1.0-ml booster doses (maximum of four boosters over 12 months) will be given if the volunteer fails to respond to the primary series with a PRNT80 ≥ 1:40 or annually if titer wanes to < 1:40.
No Intervention: no arms

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
  • 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.

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.

Exclusion Criteria

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.
