Immunoglobulin allotypes and response to tetanus toxoid in Papua, New Guinea

The data indicates that Papuans with the Austronesian haplotype Gmf,a;b produce significantly higher levels of tetanus specific antibody, than Papuans without this haplotype, suggesting that response to tetanus toxoid in man is associated with the Gm phenotype of the individual. Km (1) status was not related to response.
