This research confirms that the leading vaccine candidate found in the earlier study, named sCPD9, is also safe for Roborovski dwarf hamsters. These hamsters are prone to develop severe COVID-19-like symptoms. When the sCPD9 live-attenuated vaccine was administered through the nose, it triggered strong protective responses from the immune system. This prevented illness not only from the original SARS-CoV-2 virus but also from various SARS-CoV-2 variants of concern.
