This unresponsiveness can be overcome, however, by administering 2 injections of oil adjuvant vaccine or one injection of oil adjuvant followed 4 weeks later by an injection of alum-precipitated toxoid. The latter procedure evokes protective antitoxin levels which persist for 8 months, and a booster injection of alum-precipitated toxoid given at this stage results in an immunity which lasts for at least 1 year.en©1980 ARC - Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). ©2016 University of Pretoria Department of Library Services (digital).EnterotoxaemiaLambs -- VaccinationVeterinary medicine -- South AfricaArticle
