Abstract
Infants born to HBV carrier mothers are persistently at a higher risk for HBV infection. We investigated the association between HLA SNPs and low responsiveness to HBV vaccination, and the differences of immune response in carriers of risk genotypes who received different doses of the vaccination. 1040 infants from the prevention of mother-to-infant transmission of HBV cohort were included. Infants born to HBsAg (+) and HBeAg (â)/HBeAg (+) mothers received 10â¯Î¼g/20â¯Î¼g hepatitis B vaccine, respectively. Rs2857127, rs3135338, rs477515, rs9277554 and rs9286790 in HLA regions were well genotyped. A lower rate of low-responsiveness was observed in the 20â¯Î¼g group. Rs3135338 GG and rs9277554 TT genotype showed stronger associations with low responsiveness (Pâ¯<â¯0.05). The combination of 10â¯Î¼g vaccine with the risk genotypes was independently associated with remarkably increased risk of low-responsiveness to hepatitis B vaccines (Pâ¯<â¯0.05). HLA SNPs were associated with low-responsiveness to hepatitis B vaccine. For infants with risk genotypes, a 20â¯Î¼g dose vaccine reduced the risk of low responsiveness.
