The Dean lab of the Center for Vector-Borne Infectious Diseases has a major focus on the development of a probiotic vaccine platform utilizing the probiotic organism Lactobacillus acidophilus. Specific applications include vaccines against human rotavirus, feline coronavirus (FECV) and SARS-CoV-2. We study the host mucosal immune response and immune mechanisms of multiple adjuvant strategies. The relationship between the host microbiome and mucosal immunity and the impact of oral vaccination on the intestinal microbiome are also active areas of research. Study of the immunpathogenesis of viral infections is an overarching emphasis.
