Popis: The ultimate goal of a vaccine is to protect vaccinated animals against re-exposure to the same pathogen and provide sterile immunity. However, a cutaneous clinical manifestation appeared, following re-exposure of cattle that had been vaccinated with the RM65 strain, to LSDV infection during an epidemic in 2006-2007. Four thousand six hundred and seven vaccinated cows entered the study after being re-exposed to LSDV infection. Of them, 513 (11%) presented lumps, and there was a marked difference between the proportions of dairy and feedlot animals that were affected: 146 out of 3517 and 367 out of 1090 (6.6 and 33.7%, respectively). This data suggests that the potency of the vaccine need to be re-assessed for beef cattle.
