Antibodies from patients infected with SARS-CoV in 2003 cross-neutralised SARS-CoV-2 in vitro: Study

The authors also report that, surprisingly, mice and rabbits immunised with a receptor-binding domain (RBD) from a strain of SARS-CoV that infects the Himalayan palm civet elicited stronger antibody responses against SARS-CoV-2 than animals immunised with an RBD from a human SARS-CoV strain.

The authors suggest that their findings may inform strategies to develop universal vaccines against emerging and future coronaviruses.(ANI)
