ANTIBODY RESPONSE FOLLOWING RUBELLA IMMUNIZATION ANALYZED BY HLA TYPES

Abstract
Possible association between HLA antigens and antibody response to rubella vaccine was examined in 71 seronegative adult females, ages 18-23, immunized with QEF vaccine. High responders (HAI [hemagglutination inhibition antigen] antibody titer .gtoreq. 1:32) with HLA-B15 were significantly higher in frequency than those without HLA-B15 (P < 0.05). Subjects with HLA-A9 had a tendency toward low immune responsiveness, including the 3 non-responders. The antibody response to rubella vaccine may be influenced by the host-genetic factors relating to HLA antigens.
