While continuing to study filoviruses, Dr. Bradfute has expanded his work to include other emerging and re-emerging viral pathogens, such as hantaviruses, equine encephalitis viruses, Zika virus, and the novel coronavirus SARS-CoV-2. As there are few treatments or vaccines available for many of these viruses, the Bradfute lab studies immunology, therapeutics, diagnostics, and vaccine development for these important pathogens.
