Amino acid changes in two viral proteins drive attenuation of the yellow fever 17D vaccine - Nature Microbiology

Amino acid changes in the envelope and non-structural 2A protein attenuate the virulent yellow fever virus (YFV) and enhance host antiviral responses upon infection in vivo. These traits explain the p...
