The coronavirus disease 2019 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the world’s third major coronavirus outbreak. To date, the SARS-CoV-2 has infected over 135 million lives and caused over 2.9 million deaths.
Even as vaccines against SARS-CoV-2 are being developed and administered at an unprecedented pace, treating this infection remains a challenge.
To address this, researchers from China have used nanobodies (Nb) as a possible therapeutic approach. In a recent paper, published in the journal MedComm, they reported Nb phage display libraries derived from four camels immunized with the SARS-CoV-2 spike RBD.
