摘要

<strong>Background:</strong> In Nigeria Pentavalent vaccine had replaced Diphtheria-Pertussis- Tetanus [DPT] vaccine in the prevention of pertussis since 2012. <strong>Aims and Objectives:</strong> The aim of this study was to compare the anti-pertussis immunoglobin G (IgG) response of children who received DPT with those who received the pentavalent vaccine. <strong>Subjects and Methods:</strong> This study was carried out in Akpabuyo LGA of Cross River State from April to June 2016. It was a cross-sectional survey of anti-pertussis IgG levels in children aged 6 months to 5 years who received DPT and those who received pentavalent vaccine. IgG antibody levels were determined using enzyme-linked immunosorbent assay. The protective level was set at >11 DU according to manufacturer’s cut off point. <strong>Results:</strong> Seventy eight out of 230 children [33.9%] who had received DPT had protective levels of anti-pertussis IgG compared to 74 out of 192 children [38.5%] who had received pentavalent vaccine. The difference was not statistically significant [<em>p</em> = 0.61]. The median IgG antibody level in those who received DPT was 8.0 DU (interquartile range (IQR) 4.0 - 13.0) compared with 9.0 DU (IQR) 4.0 - 15.0 in those who received pentavalent vaccine [<em>p</em> = 0.18]. No single factor investigated predicted the development of protective levels of antibody in the multivariate analysis. <strong>Conclusion/Recommendation:</strong> There was no difference in the antipertussis antibody response between DPT and pentavalent vaccines recipients. Further study is needed to elucidate factors that could be responsible for low anti-pertussis antibody response in this population.
