Design, survival and viremia of the second rechallenge experiment.
(A) Six NHPs were rechallenged 9 weeks after the end of their first challenge: first challenge at week 0; first challenge ends at week 4; rechallenge begins at week 13. (B) survival of the second set of rechallenge cynomolgus macaques along with two controls of the same species. (C) Viremia during the second rechallenge, as measured by TCID50.
