The second international standard for tetanus toxoid (adsorbed)

J Lyng et al. J Biol Stand. 1984 Jan.

Abstract

The stocks of the first International Standard for Tetanus Toxoid, Adsorbed are exhausted and a second International Standard was established in 1981. An international collaborative assay arranged to calibrate the second International Standard revealed that the first and the second International Standards are not strictly comparable. It is indicated that the problems encountered are general problems in the potency assay of adsorbed tetanus toxoids.
