Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • At least 18 years old.
  • Females of childbearing potential must agree to have a urine pregnancy test on the same day before receipt of skin test AND vaccine. (Exception: documented hysterectomy or ≥ 3 years of menopause.) The results must be negative. Females must agree to not become pregnant for 3 months after receipt of the skin test or vaccination.
  • Considered at risk for exposure to C burnetii and who have submitted a Request for Investigational New Drug (IND) Vaccines for the Q Fever vaccine.
  • Sign and date the approved informed consent document and Health Insurance Portability and Accountability Act (HIPAA) Authorization.

  • Have on their charts:

    • Up-to-date medical history (including concomitant medications)
    • Physical examination and laboratory tests within 1 year
    • Previous chest x-ray and electrocardiogram
  • Be medically cleared for participation by an investigator. Examinations or tests may be repeated at the discretion of the enrolling physician.
  • Willing to return for all follow-up visits.
  • Agree to report any adverse events (AEs) that may or may not be associated with administration of the test article for at least 28 days after vaccination and agree to report all serious adverse events (for example, resulting in hospitalization) for the duration of the subject's participation in the study (6 months).
  • Agree to defer blood, bone marrow, and organ donation for 1 year after receipt of skin test antigen and/or vaccine.

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 principal investigator).
  • Personal history of an immunodeficiency or current treatment with an oral or intravenous immunosuppressive medication.
  • Confirmed HIV infection.
  • Heart valve disease: prosthetic heart valve or clinically significant heart murmur. (If a murmur is detected on examination, an echocardiogram may be obtained or subject may be referred to a cardiologist to determine clinical significance.)
  • Aneurysm/vascular graft.
  • Joint prosthesis.
  • History of chronic fatigue syndrome (or positive by chronic fatigue syndrome (CFS) Questionnaire criteria).
  • Positive pregnancy test or breast-feeding female.

  • Any known allergies to components of the vaccine:

    • Formalin
    • Eggs or chicken products
  • Administration of another vaccine or investigational product within 28 days of skin test and subsequent Q fever vaccination.
  • Any unresolved AE resulting from a previous immunization.
  • Transplant recipients, subjects with cancer, and those with chronic kidney disease.
  • A medical condition that, in the judgment of the principal investigator, would impact subject safety.
