  6. Subject must sign and date the approved informed consent document.
  7. For initiation of primary series, RVF PRNT80 <1:10.
  8. For RE-ENTRY into this protocol or ROLLOVER from an earlier RVF protocol to receive a booster, RVF PRNT80 <1:40 within past 1 year

Exclusion criteria

  1. Older than 65 years of age for the primary series vaccination (able to receive booster doses if no other contraindications).
  2. Clinically significant abnormal lab results, including evidence of Hepatitis C, Hepatitis B carrier state, or elevated (2 times normal) liver function tests.
  3. Personal history of immunodeficiency or current treatment with immunosuppressive medication.
  4. Confirmed positive human immunodeficiency virus (HIV) titer.
  5. Any medical condition that, at the discretion of the physician, may jeopardize the safety of the subject.
  6. Any serious or life-threatening allergies to any component of the vaccine: formalin human serum albumin neomycin streptomycin fetal rhesus lung cells RVF virus inactivated
