Nagata, Utsumi, Asaka, Maeda et al. describe a nanobody, TP86, that potently neutralizes both BA.1 and BA.2 Omicron SARS-CoV-2 variants, and, when combined with the TP17 nanobody, broadly neutralizes all SARS-CoV-2 variants. This nanobody cocktail also suppresses weight loss and prolongs survival of SARS-CoV-2 infected human ACE2 transgenic mice.
