Abstract
Dermal delayed hypersensitivity and in vitro lymphocyte reactivity, both to purified influenza antigens, have been observed in man. A correlation between these two indices of delayed hypersensitivity was found in subjects without known recent exposure to the virus, but neither correlated with levels of circulating haemagglutination-inhibiting (HAI) antibody. Results suggest that in man immunological sensitization of lymphocytes to influenza virus antigen is long-lived.Entities:
