Fig. 3: Experimental design and antibody responses to vaccination in Syrian hamsters.

a Adult Syrian hamsters (n = 4) were vaccinated with MVA-S, MVA (empty vector), or PBS on days 0 and 21 with blood collection weekly until challenge in week 6. b Sera from collected blood samples were tested for neutralizing antibody at each week for 6 weeks and at 4 days post challenge. c Sera were tested for S-specific IgG at weeks 1, 3, and 6. ****P < 0.0001.
