The immune response to hepatitis B vaccination varies among individuals. It has been reported that polymorphisms in cytokine and cytokine receptor genes are associated with these individual differences. The aim of the current study was to investigate the association between polymorphisms of the Th1/Th2 cytokine and cytokine receptor genes and the response to hepatitis B vaccination in a Chinese Han population. A total of 10 single nucleotide polymorphisms distributed in 6 genes (TNFRSF1A, IL12A, IL12B, IFNG, IL4, and IL10) were genotyped in 214 high‐responders [hepatitis B surface antibody (anti‐HBs) ≥1,000 mIU/ml] and 107 low‐responders (anti‐HBs: 10–99 mIU/ml). The minor CTCTAA allele of rs17860508 in the IL12B gene was associated with a low response to hepatitis B vaccination ( P = 0.039, odds ratio = 1.41, 95% confidence interval = 1.00–1.99). In addition, a significant gene–gene interaction was found: the frequency of the combined genotypes IL12A rs2243115 TT and IL12B rs17860508 CTCTAA/CTCTAA was significantly higher in the low‐response group than in the high‐response group ( P = 0.008, odds ratio = 2.19, 95% confidence interval = 1.23–3.93). These findings suggest that polymorphisms in the IL12A and IL12B genes might play an important role jointly in determining the response to hepatitis B vaccination. J. Med.
