Abstract
The use of IEOP is described for screening blood donors to find plasma containing tetanus antitoxin suitable for fractionation. Preliminary results indicate that most recipients of tetanus toxoid are unlikely to have acceptable antitoxin levels for much longer than about three months after inoculation. A small number of recipients maintain acceptable levels even for many years without further known boosting. Such people can now be identified easily, among the 5% of all East Anglian donors who have antitoxin levels of at least 5 1U/ml.
