Abstract
The emergence of SARS-CoV-2 variants of concern (VoCs) has exacerbated the COVID-19 pandemic. Currently available monoclonal antibodies and vaccines appear to have reduced efficacy against some of these VoCs. Antivirals targeting conserved proteins of SARS-CoV-2 are unlikely to be affected by mutations arising in VoCs, and should therefore be effective against emerging variants. We here investigate the efficacy of Molnupiravir, currently in phase II clinical trials, in hamsters infected with either Wuhan strain, B.1.1.7 or B.1.351 variants. Molnupiravir proved to be effective against infections with each of the variants and therefore may have potential combating current and future emerging VoCs.
Keywords: Antivirals; B.1.351; Molnupiravir; SARS-CoV-2; VoC; coronavirus; hamsters.
