Ferret models of SARS-CoV-1 also demonstrate virus replication in respiratory tracts with induction of a neutralizing antibody response but also demonstrated little evidence of clinical disease [13] . Efficacy of several SARS-CoV-1 vaccines was evaluated in these models with spike (S) protein based vaccines demonstrating neutralizing antibody and protection against pulmonary replication of the challenge virus in mice and hamsters [16] . There is evidence for disease enhancement in vaccinated animals after challenge with live virus in multiple studies with SARS-CoV-1 vaccine candidates as summarized in Table. Chinese macaques immunized with a modified vaccinia virus expressing S protein then challenged with SARS-CoV-1 did not develop clinical disease, but histopathology showed lung injury. ./cache/cord-294856-eeh2a0t8.txt ./txt/cord-294856-eeh2a0t8.txt
