(A) Body mass of mice from each group (both prophylactic and therapeutic) was recorded for 6 days post-infection. The Y-axis represents the body mass of the mouse relative to the body mass of the same mouse recorded on day 0 (normalised to 100) (dpi, days post-infection). (B) Animal challenge experiment performed with prophylactic or therapeutic intervention of P4A2 antibody. Briefly, animals challenged with Wuhan, Kappa, Delta or Beta SARS-CoV-2 strain (105 pfu/ mice) were given prophylactic (1 day prior to challenge) or therapeutic dose (12 h post challenge) and representative images of the excised lung showing inflammation and pneumonitis.
