Antibody kinetics, peak response, and decay rate among blood culture-confirmed enteric fever cases by study country

All comparisons are among children aged 5 to 15 years to account for the different age-distribution of cases across countries. (A) Median longitudinal antibody decay profiles fit to ELISA-measured antibody responses in each study country. (B) Box plots of model-predicted peak antibody responses and annual antibody decay rates across study countries. HlyE=hemolysin E. LPS=lipopolysaccharide.
