Primary Outcome Measures :
  1. Percentage of Subjects With at Least 4-fold Increase in Anti-Vi Enzyme-linked Immunosorbent Assay (ELISA) Titer [ Time Frame: At 28 days after last vaccination as compared to baseline ]
  2. Percentage of Subjects With at Least 4-fold Increase in Anti-Vi ELISA Titer [ Time Frame: At 6 months after last vaccination as compared to baseline ]
  3. Anti-Vi ELISA Geometric Mean Concentration (GMC) [ Time Frame: At 28 days after last vaccination ]
  4. Anti-Vi ELISA GMC [ Time Frame: At 6 months after last vaccination ]

Secondary Outcome Measures :
  1. Number of Participants With Any Solicited Local and Systemic Reaction, After Any Vaccination [ Time Frame: During the 7-day follow-up period after vaccination ]

    Solicited local reactions were: Adults, children, older infants, infants: erythema, induration and pain/tenderness at the injection site.

    Solicited systemic reactions were: Adults: chills, malaise, myalgia, arthralgia, headache, fatigue, rash and fever.

    Children, older infants and infants: lethargy, irritability, vomiting, diarrhoea, loss of appetite, rash and fever (and persistent crying in infants).
