Importance of HBsAg recognition by HLA molecules as revealed by responsiveness to different hepatitis B vaccines
Abstract Hepatitis B (HB) vaccines (Heptavax-II and Bimmugen) designed based on HBV genotypes A and C are mainly used for vaccination against HB in Japan. To determine whether there are differences in the genetic background associated with vaccine responsiveness, genome-wide association studies were...
