New vaccine technology produces more antibodies against SARS-CoV-2 in mice

A new technology developed at Caltech is designed to make more potent vaccines, beginning with SARS-CoV-2 (the virus that causes COVID-19). In mouse studies, the prototype vaccine elicited five times more antibodies than current COVID-19 vaccines. The antibodies produced by the new vaccine were effective against the original strain of SARS-CoV-2, the delta variant, and omicron variants.
