Probiotics have been shown to enhance specific immune responses to vaccines. We aim to assess the effect of probiotic supplementation on specific IgG antibody responses to Hepatitis B (HepB) vaccination in infants. Compared to controls, probiotic supplementation improved HepB surface antibody responses in subjects receiving monovalent doses of HepB vaccine at 0, 1 month and a DTPa–HepB combination vaccine at 6 months [placebo (n=28): 187.97 (180.70–195.24), probiotic (n = 29): 345.70 (339.41–351.99) mIU/ml] (p = 0.069), but not those who received 3 monovalent doses [placebo (n = 68): 302.34 (296.31–308.37), probiotic (n = 77): 302.06 (296.31–307.81) mIU/ml] (p = 0.996). Probiotics may enhance specific antibody responses in infants receiving certain Hepatitis B vaccine schedules.
