ABSTRACT
Salmonella typhi Ty21a vaccine in a liquid formulation was evaluated in 634 Thai children 2 to 6 years of age. The seroconversion rate was 69% for those who received vaccine versus 14% for those who received placebo (P < 0.005). The immune responses among vaccine recipients ranged from 60% in 3-year-olds to 81% for 6-year-olds.
