Primary Outcome Measures:
  • The adverse reaction and occupational illness endpoint measurements in this Q fever NDBR 105 vaccine study will be evaluated for all intent-to-treat volunteers. [ Time Frame: AEs recorded through day 28 after vaccination; SAEs recorded through duration of study; Confirmed occupational illness recorded through duration of study ] [ Designated as safety issue: No ]

Estimated Enrollment: 500

No arms
Biological: Q-Fever Vaccine, NDBR 105
Each volunteer will receive an intradermal dose of 0.1 ml of the skin test antigen (Q fever Skin Test Antigen, Henzerling Strain, Phase I, MNLBR 110) in the volar aspect of the arm on Day -7 of the study.Volunteers with skin test reactions that are considered negative may be vaccinated with Q Fever Vaccine, Phase I, Inactivated, Freeze-Dried, NDBR 105 (subcutaneously, 0.5 ml) in the upper outer aspect of the arm on Day 0 of the study.

Detailed Description:

Study Objectives:

1. Continue to collect and assess safety data on Q Fever Vaccine, Phase I, Inactivated, Freeze-Dried, NDBR 105, and 2) Provide vaccine that potentially protects personnel at risk for occupational exposure to Q Fever and collect data on incidence of occupational Q Fever infection (subclinical and clinical) in immunized personnel.

Ages Eligible for Study:   17 Years to 65 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • At least 18 years old, or if on active military duty, 17 years old.
  • Females of childbearing potential must agree to have a urine pregnancy test on the same day before receipt of skin test antigen AND vaccine. (Exception: documented hysterectomy or > three years of menopause.) The results must be negative.
  • Volunteer must be actively enrolled in the SIP
  • Volunteer must be considered at risk for exposure to C. burnetii.
  • Volunteer must sign and date the approved ICD and HIPAA Authorization.
  • Volunteer must have an up-to-date (within one year) medical history, physical examination, and laboratory tests on their charts and be medically cleared for participation by an Investigator. Examinations or tests may be repeated within one year at the discretion of the enrolling physician.
  • Volunteer must be willing to return for all follow-up visits.
  • Volunteer must agree to report any AEs which may or may not be associated with administration of the test article for at least 28 days after vaccination. All SAEs and UAEs will be reported for the duration of the volunteer's participation in the study (one year).

Exclusion Criteria:

  • Prior history of Q fever disease or vaccination.
  • Clinically significant abnormal lab results including evidence of Hepatitis C, Hepatitis B carrier state, or elevated liver function tests (two times the normal range or at the discretion of the PI).
  • Personal history of an immunodeficiency or current treatment with an immunosuppressive medication or autoimmune disease.
  • Confirmed HIV infection.
  • Heart valve disease: murmur with abnormal echocardiogram (if murmur is detected on examination, volunteer will be referred to cardiologist to rule out pathology.)
  • Positive pregnancy test or lactating female (females must agree to not become pregnant for three months after vaccination.)
  • Any known allergies to components of the vaccine.
  • Administration of another inactivated vaccine within 7 days or a live or IND vaccine within 28 days of Q fever vaccination.
  • Any unresolved AE resulting from a previous immunization.
