Three horses were immunized intramuscularly (IM) with 7 injections of eVLP over 11 weeks and the hyperimmune sera were collected from each animal at specified timepoints ( Fig. 1A) to determine the serum titers by neutralization assay against a recombinant HIV-1 virus pseudotyped with EBOV GP. The observation that administering F(ab′ ) 2 at 1 dpi is more efficacious than when the same treatment was given at 30 minutes post-exposure (Fig. 5A ) was also observed in past studies with therapeutic EBOV GP-specific monoclonal antibodies 25, 26 , and suggests that virus neutralization may play a bigger role in protection at a later timepoint after EBOV challenge. ./cache/cord-002013-rb9xdzro.txt ./txt/cord-002013-rb9xdzro.txt
