Our data show that horses immunized with MERS-CoV VLPs can serve as a primary source of protective F(ab')(2) for potential use in the prophylactic or therapeutic treatment of exposed or infected patients. Several research groups have developed and produced anti-MERS patientderived or humanized monoclonal neutralizing antibodies in vitro that were able to protect MERS-CoV infected mice (Corti et al., 2015; Li et al., 2015; Zhao et al., 2014) . Prophylactic or therapeutic treatment of MERS-CoV infected mice with either IgG or F(ab') 2 significantly decreased the virus load in their lungs. In both prophylactic and therapeutic settings, passive transfer of equine immune antibodies resulted in a 2e4 log reduction of virus titers in the lungs of MERS-CoV infected mice, and accelerated virus clearance in the serum treated group (Fig. 5A, B) . ./cache/cord-263042-qdmunb9l.txt ./txt/cord-263042-qdmunb9l.txt
