A maximal immunity response is brought about by two injections each containing 90 Lf toxoid. The interval between the primary and secondary stimuli may vary from two to six weeks without influencing the end result.en© 1967 ARC - Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). © 2016 University of Pretoria.
