title: Reexamination of the efficacy of vaccination against mousepox.
abstract: Experiments were conducted to evaluate the efficacy of three strains of vaccinia virus, IHD-T, Lister and Wyeth, to immunize the BALB/cByJ mouse against infection with ectromelia virus. Mice vaccinated with any of the strains were protected for at least 12 weeks against clinically apparent disease when challenged with cage-mates infected with a virulent stain (NIH-79) of ectromelia virus. However, 4 to 8 weeks after vaccination mice were capable of transmitting virus to non-vaccinated cage-mates. The results are discussed within the context of the current practices for preventing and controlling ectromelia epizootics.
