Outcome Measures
Primary Outcomes (1)
IGRA status per site
Proportion of participants with a positive IGRA, per site, calculated using per protocol population. 95% CI will summarize the precision associated with the estimate.
Screening
Secondary Outcomes (3)
IGRA status by age group per site
Screening
Suspected pulmonary TB during follow-up period
Day 1 up to 30 months
Laboratory-confirmed pulmonary TB during follow-up period
Day 1 up to 30 months
Eligibility Criteria
A maximum of 7,203 participants who are at high risk of Mtb infection and TB (disease) will be enrolled.
You may qualify if:
- Between 15 and 34 years of age (inclusive)
- Participants who agree to stay in contact with the study site for the duration of the study, provide updated contact information as necessary, and have no current plans to relocate from the study area for the duration of the study.
You may not qualify if:
- History of active TB within the last 24 months (i.e., 24 months from end of treatment to day of screening, based on history \[no documentation required\])
- History of previous administration of an experimental Mtb vaccine
- Unstable / uncontrolled chronic condition according to the judgment of the investigator
