title: Recruitment and plasmapheresis of donors to provide human antitetanus immunoglobulin.
abstract: A method is described whereby about 100 litres of plasma containing 10-50 IU/ml tetanus antitixin was obtained, from which were prepared 5000 X 250 IU doses of human antitetanus immunoglobulin. Of 40 blood donors who received a booster injection of tetanus vaccine BP, 33 were plasmapheresed each week over a 10-12 week period starting three weeks after the injection. Twenty-two of these donors provided 90% of the total plasma, the antitoxin content of which averaged 23.6 IU/ml over the 10-12 week period.
