Experimental design and survival for the first rechallenge experiment.
(A) Six nonhuman primates which survived a first challenge (at week 0) were kept for 6 weeks after the end of that challenge (week 4) and were rechallenged with the same virus (at week 10); (B) survival curve showing complete survival in cynomolgus macaques rechallenged with EBOV, the rhesus controls were part of an unrelated experiment conducted. (C) Table showing the time to death of historical cynomolgus macaque controls.
