Prior/Concomitant Therapy
- History of receiving any typhoid vaccine (Ty21a, Vi capsular polysaccharide, or TCV) in the participant’s life.
- History of receiving any investigational iNTS or GMMA vaccines in the participant’s life.

- Chronic administration (defined as more than 14 days in total) of immunosuppressants or other immune modifying drugs during the period starting 3 months prior to the first study intervention dose(s). For corticosteroids, this will mean prednisone equivalent ≥20 mg/day for adult participants. Inhaled and topical steroids are allowed.
Prior/Concurrent Clinical Study Experience

Other Exclusions
- Pregnant or lactating female
- Female planning to become pregnant or planning to discontinue contraceptive precautions
