About this trial
The purpose of this study is to evaluate the safety, reactogenicity, and immune response induced by the GlaxoSmithKline Biologicals SA (GSK) Vaccines Institute for Global Health (GVGH) invasive nontyphoidal Salmonella-typhoid conjugate (iNTS-TCV) vaccine in infants with the first dose administered at 6 months of age (MOA) or 6 weeks of age (WOA).

Trial outcomes
Primary outcomes
Number of participants with solicited administration site events during 7 days after each study intervention administration [for infants 6 MOA]
Solicited administration site events included pain, redness, and swelling.
Number of participants with solicited systemic events during 7 days after each study intervention administration [for infants 6 MOA]
Solicited systemic events included Fever, Irritability/Fussiness, Loss of appetite, Somnolence (sleepiness/drowsiness) and Vomiting. Fever is defined as body temperature more than or equal to (\>=) 37.5 degrees Celsius (°C), measured from axilla.
Number of participants with unsolicited adverse events (AEs) during 28 days after each study intervention administration [for infants 6 MOA]
An unsolicited AE is defined as an AE that was either not included in the list of solicited events or could be included in the list of solicited events but with an onset outside the specified period of follow-up for solicited events.
Number of participants with serious adverse events (SAEs) [for infants 6 MOA]
An SAE is defined as any untoward medical occurrence that results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect in the offspring of a study participant, results in abnormal pregnancy outcomes or any other situation based on appropriate medical or scientific judgement.
Secondary outcomes
