INTERVIEW: Dr Jacco Boon on a possible new nasal vaccine for COVID-19

Researchers using a nasal vaccine approved in India and licensed for U-S development found that vaccinated hamsters didn’t spread the virus, unlike those receiving traditional injected vaccines. Published on July 31 in Science Advances, these findings indicate that mucosal vaccines could be crucial for controlling respiratory infections like COVID-19 and influenza. Essam Al-Ghalib spoke with the study's author, Jacco Boon, a professor of medicine, of molecular microbiology and of pathology and immunology.
