Table 3.
Anti-Vi IgG antibody immunogenicity before vaccination (day 0) and 28 days after vaccination.
| Group 1: TCV (N = 49) | Group 2: IPV (N = 51) | |
|---|---|---|
| Seroconversiona (%, 95% CI) | 43/49 (87·8%, 75·2–95·4) | 4/50b (8·0%, 2·2–19·2) |
| Day 0 geometric mean titer (95% CI) | 8·9 (5·9–13·6) | 8·5 (5·6–12·7) |
| Day 28 geometric mean titer (95% CI) | 1203·7 (747·1–1939·5) | 8·9b (6·1–13·1) |
N = total number, CI = confidence interval.
Geometric mean titer in ELISA units (EU)/mL.
a
≥4-fold rise from day 0 to 28 days after vaccination.
b
One participant in the IPV group missing titer, n = 50.
