Inhaled COVID-19 vaccine prevents disease and transmission in animals

By: Jennifer Brown Date: Tuesday, July 6, 2021 In a new study assessing the potential of a single-dose, intranasal COVID-19 vaccine, a team from the University of Iowa and the University of Georgia found that the vaccine fully protects mice against lethal COVID-19 infection. The vaccine also blocks animal-to-animal transmission of the virus. The findings were published July 2 in the journal Science Advances. The currently available vaccines against COVID-19 are very successful, but the majority of the world’s population is still unvaccinated and there is a critical need for more vaccines that are easy to use and effective at stopping disease and transmission,  says Paul McCray, MD, professor of pediatrics-pulmonary medicine, and microbiology and immunology at the UI Carver College of Medicine, and co-leader of the study. If this new COVID-19 vaccine proves effective in people, it may help block SARS-CoV-2 transmission and help control the COVID-19 pandemic.
