SARS-CoV-2 B.1.1.7 (alpha) and B.1.351 (beta) variants induce pathogenic patterns in K18-hACE2 transgenic mice distinct from early strains

Mutant SARS-CoV-2 strains such as B.1.1.7 and B.1.351 have been termed variants of concerns (VoC) due to their enhanced virulence. Here the authors show, using K18-hACE2 transgenic mouse models, that these two VoCs are also more pathogenic in mice, and induce immunity and pathology distinct from those from the earlier variants.
