Anti-Neu5Gc IgM/IgG ELISA data are shown in terms of mean OD+/-SD (p value), which was calculated using mean OD minus negative control OD.

Bacillus Calmette Guerin and Heptatitis B vaccines: anti-Neu5Gc IgG (N) vs anti-Neu5Gc IgG (Y) P<0.05.

Typhoid vaccine: anti-Neu5Gc IgG (N) vs anti-Neu5Gc IgG (Y) P<0.01.

*The number who had received the diphtheria/pertussis/tetanus vaccine (n = 3) was too small for statistical analysis.
