Bioavailability study of diphtheria immunoglobulin (human)

A diptheria immunoglobulin has been prepared from selected blood donations to the Australian Red Cross Transfusion Services. A dose of 250 I.U. has been demonstrated to raise the titre of diptheria antitoxin in non-immune subjects to protective levels within 24 h, and these levels remain protective for at least 5 wk. Supplies are available from the various branches of the Australian Red Cross Transfusion Services.
