Intranasal delivery of a rationally attenuated SARS-CoV-2 is immunogenic and protective in Syrian hamsters
Abstract
Examples of effective live attenuated viral vaccines include the measles, mumps and rubella vaccine, as well as the chickenpox vaccine. In this work, the authors engineer a live attenuated SARS-CoV-2 virus that demonstrates attenuation in numerous in vivo models, and protection in hamsters upon challenge.
