Mucosal immunization with an attenuated Salmonella vaccine partially protects white-tailed deer from chronic wasting disease

Illustrates the study design of the CWD vaccination experiment. There were five vaccinated white-tailed deer and 6 vehicle controls. Deer were matched for Prnp genotype (95Q/96G/116A/138S/226Q), except two deer in both the control and vaccinated group had the most common polymorphism (∼26% of deer) that confers partial resistance to CWD infection, codon 96 G/S instead of 96 G/G.
