This is a Phase II/III trial with two groups of adults successfully cured of category 1 pulmonary TB receiving either VPM1002 or placebo. Single dose of VPM1002 / placebo will be administered to calculate efficacy of the vaccine against TB recurrence.

The study is designed as a multicenter, double-blinded, randomized, placebo-controlled trial with two groups of category 1 pulmonary TB patients who have successfully completed ATT and declared cured by bacteriological confirmation.

The eligible participants will be randomized in 1:1 ratio to receive single dose of either VPM1002 or placebo. After study vaccination, participants will be followed up for one year. Any suspected TB case during follow up will be further evaluated and bacteriologically confirmed. Study participants will be actively followed up for 2 months post-vaccination for any solicited local and regional reaction. SAEs will be recorded and reported throughout study participation.

Inclusion Criteria:

1. Males or females aged ≥18 and ≤65 years.
2. Bacteriologically confirmed Category I pulmonary TB patients (including controlled diabetics with HbA1c level ≤7% and non-diabetics) who successfully completed ATT as per national guidelines.
3. Must have a sputum sample showing bacteriologic confirmation of cure - defined as smear negative.
4. Female participants who are currently using reliable methods of birth control, have a negative pregnancy test during screening and have no intention to become pregnant for at least 3 months post-vaccination.
5. Participant must intend to remain in the area during the study period.

Exclusion Criteria:

1. Reactive serology for HIV
2. History of extrapulmonary TB
3. Known or suspected impairment of immunological function
4. Pregnant and / or lactating female participants
