title: The effect of passive immunization against tetanus toxoid in man.
abstract: The present study deals with the immunological response in man after passive immunization against tetanus toxoid. Treatment of man with equine antitetanus serum stimulates a rise of E rosette-forming T lymphocytes. The level of IgG also rises while the level of IgM falls. It is assumed that the foreign globulin acts as an antigen that evokes the T lymphocytes' co-operation for the humoral immune response with a switch from IgM to IgG synthesis.
