Background: In Nigeria and many parts of the world, the pentavalent vaccine is replacing the diphtheria-pertussis-tetanus (DPT) vaccine in tetanus prevention. Aims and Objectives: The aim of this study was to compare the anti-tetanus immunoglobulin G (IgG) response of children who received DPT with those who received the pentavalent vaccine. Subjects and Methods: A cross-sectional survey of anti-tetanus IgG levels in children aged 6 months to 5 years who received DPT and in children who received the pentavalent vaccine. IgG antibody levels were determined using enzyme-linked immunosorbent assay. The protective level was set at ≥0.1 IU/ml. Results: One hundred and twenty-two out of 130 children (93.9%) who had received DPT had protective levels of anti-tetanus IgG compared to 278 out of 288 children (96.5%) who had received the pentavalent vaccine. The difference was not statistically significant (P = 0.21). The median IgG antibody level in those who received DPT was 1.1 IU/ml (interquartile range (IQR) 0.4–1.8) compared with 0.6 IU/ml (IQR 0.4–1.4) in those who received pentavalent vaccine (P = 0.006), with age being the only predictor of variability in the multivariate analysis. Conclusion/Recommendation: DPT and pentavalent vaccines are equally effective in inducing protective levels of anti-tetanus IgG in children. Vaccination with the pentavalent vaccine, which is the current policy in Nigeria and many other parts of the world, should continue.
