Description
Inclusion Criteria (CF and non-CF bronchiectasis):
- Confirmed diagnosis of either CF or non-CF bronchiectasis
- Forced expiratory volume over one second (FEV1) > 40%
- Willingness to participate in the study after all aspects of the protocol have been explained and written informed consent obtained.
- Available for the study duration, including all planned follow-up visits
Inclusion Criteria (Healthy Volunteers):
- Negative HIV enzyme-linked immunosorbent assay (ELISA) and confirmatory test at screening.
- Willingness to participate in the study after all aspects of the protocol have been explained and written informed obtained.
- Available for the study duration, including all planned follow-up visits
Exclusion Criteria (All arms):
- Current or prior history of active or latent tuberculosis (TB) (per report, not formally tested) or NTM infection
- Prior BCG vaccination
- Previous vaccine in the past 4 weeks
- History of severe anaphylaxis to any vaccine or vaccine components
- History of organ/bone marrow transplantation or other immunosuppressing condition, including HIV
- Immunosuppressing drugs (including oral corticosteroids equivalent to >10mg of prednisone for 5 days) in the 30 days prior to study enrollment
- Cirrhosis or portal hypertension
- Pregnant or breastfeeding
- Receipt of another investigational product in the last 28 days or planned receipt during this study

BCG Uptake
Time Frame: 3 months
|
Change in concentration of interferon (IFN) gamma levels in blood after Bacille Calmette-Guérin (BCG) incubation relative to baseline as measured by SFUs.
Spot forming units (SFU) is a measure of immune response of mononuclear cells in response to M. avium lysate.
Higher values indicate a stronger immune response.
