Active immunization against tetanus in man. II. Combined active and passive prophylaxis with human tetanus immune
Abstract:
19 Persons were actively immunized with adsorbed tetanus toxoid and were simultaneously given tetanus immune globulin of human origin, TIG(H), in doses of 500-1500 IU. Their antitoxin titres were followed for 1 year. Seven persons were given only TIG(H), 500 IU and 1500 IU and their antitoxin titres were followed for 3 months to 1 year. For comparison, 30 military recruits were actively immunized with adsorbed tetanus toxiod according to common practice. Their antitoxin titres were followed for 1 year. The response to complete active immunization could not be demonstrated to be impaired by passive immunization, when 500 IU or 1500 IU OF TIG(H) were given simultaneously with toxoid. The titres were in accordance with those achieved by active immunization of the recruits.
