The modified SARS-CoV-2 antigen, 264 RBD219-N1C1, when formulated on Alhydrogel ® , was shown to induce virus-neutralizing antibodies 265 in mice, equivalent to those levels elicited by the wild-type (RBD219-WT) recombinant protein 266 counterpart. Here we report on a yeast-expressed SARS-CoV-2 RBD219-N1C1 protein and its potential as a 397 vaccine candidate antigen for preventing COVID-19. In a mouse virus challenge model for the SARS CoV RBD recombinant protein vaccine, we 422 found that Alhydrogel ® formulations induced high levels of protective immunity but did not 423 stimulate eosinophilic immune enhancement, suggesting that Alhydrogel ® may even reduce immune The selection of the P.	./cache/cord-287205-k64svq6n.txt	./txt/cord-287205-k64svq6n.txt
