Safety Evaluation of a Q-fever Vaccine, NDBR 105

Phase 2

Completed

Brief Summary: The purpose of this study is to evaluate the safety of Q Fever vaccine, NDBR 105, and collect data on incidence of occupational Q Fever infection in at risk personnel.

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.

Recruitment & Eligibility

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.

Arm && Interventions

Group	Intervention	Description
Q Fever Vaccine (NDBR 105)	Q Fever Vaccine (NDBR 105	Volunteers will receive and intradermal dose of 0.1 ml of the skin test antigen (Q fever Skin Test Antigen, Henzerling Strain, Phase 1, MNLBR 110) in the volar aspect of the arm. Skin test will be evaluated; if erythema occurs after the skin test, it is medically contraindicated to vaccinate that volunteer. Volunteers with skin test reactions will not be vaccinated and withdrawn from the study.

Primary Outcome Measures

Name	Time	Method
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.	AEs recorded through day 28 after vaccination; SAEs recorded through duration of study; Confirmed occupational illness recorded through duration of study	Observe adverse reactions and occupational illness endpoint measurements 7 days follow-up after receipt of skin test antigen and 12 months of follow-up after receipt of vaccine
