"...The research community is in desperate need of animal models for testing therapeutics and vaccines against coronavirus disease 2019 (COVID-19), and for studies aimed at understanding the molecular mechanisms of severe acute respiratory syndrome (SARS) coronavirus (CoV) 2 (SARS-CoV-2) infection and pathogenesis. A wide spectrum of laboratory and domestic animal species have been challenged with SARS-CoV-2 in an effort to find suitable models, but only a few, such as hamsters, cats, ferrets and monkeys, are susceptible<a data-track="click" data-track-action="reference anchor" data-track-label="link" data-test="citation-ref" title="Shi, J. et al.

Unfortunately, many of these species are neither accessible nor practical for the vast majority of researchers to make rapid progress.
Mice are the most commonly used laboratory animals in biomedical research, and they have helped scientists develop diagnostics, therapeutics and vaccines for many human diseases. As such, it would have been easy to use mice for COVID-19 research if they were susceptible to SARS-CoV-2 infection, like humans, but that is not the case. One way to render mice susceptible to SARS-CoV-2 is to genetically modify them.
