Outcome Primer | • Number and percentage of infants with at least one adverse event (local reaction or systemic event), solicited and/or unsolicited within 30 minutes, 24 hours, 48 hours, 72 hours, 7 days and 28 days after vaccination. • Number and percentage of infants with seroconversion defined as 4-fold increase in antibody titer 28 days after vaccination compared to baseline |
Outcome Skunder | Safety: • Number and percentage of adults, adolescents and children with at least one adverse event, solicited or unsolicited, within 30 minutes, 72hours and 28 days after vaccination. • Number and percentage of subjects with serious adverse event from inclusion until 28 days after vaccination • Comparison of safety data between Vi-DT and Vi Polysacharride/Inactivated Poliomyelitis Vaccine groups. Immunogenicity: Assessment of immunogenicity of typhoid conjugated vaccine (Vi-DT) with Vi Polysaccharide vaccine using the following criteria: • Number and percentage of adults, adolescents and children with seroconversion defined as 4-fold increase in antibody titer of anti-Vi IgG one month after vaccination compared to baseline. • Geometric Mean Titre of anti-Vi IgG in all groups in each serology schedule. • Comparison of seroconvergence defined as percentage of subjects with increasing anti-Vi IgG ≥ 4 times between Vi-DT and Vi Polysscharride in each age group. • The anti-Vi IgG antibody kinetic at 24 weeks and 48 weeks after primary dose vaccination in all groups. • Serological response to Measles vaccine in infants group (≥ 9 months -23 months). Percentage of subjects with anti Measles IgG titer 8 (1/dil) 28 days after one dose of MR vaccine, GMT, percentage of infants with increasing antibody titer 4 times and/or percentage of infants with transition of seronegative to seropositive. • Serological response to Rubella vaccine in infants group (≥ 9 months -23 months). Percentage of subjects with anti Rubella IgG titer 11 IU/mL 28 days after one dose of MR vaccine, GMT, percentage of infants with increasing antibody titer 4 times and/or percentage of infants with transition of seronegative to seropositive. |
