Researchers from Duke University have developed a nasal vaccine formulation that provides protective immunity against West Nile virus (WNV) infection in mice after only 2 doses. They presented their findings at the 2014 American Society for Microbiology Biodefense and Emerging Diseases Research Meeting."Our results demonstrate that a needle-free WNV vaccine using only 2 vaccine doses is able to induce protective anti-WNV immunity," says Herman Staats, a researcher on the study.
