Receptor binding site-deleted foot-and-mouth disease (FMD) virus protects cattle from FMD

T S McKenna et al. J Virol. 1995 Sep.

Abstract

Binding of foot-and-mouth disease virus (FMDV) to cells requires an arginine-glycine-aspartic acid (RGD) sequence in the capsid protein VP1. We have genetically engineered an FMDV in which these three amino acids have been deleted, producing a virus particle which is unable to bind to cells. Cattle vaccinated with these receptor binding site-deleted virions were protected from disease when challenged with a virulent virus, demonstrating that these RGD-deleted viruses could serve as the basis for foot-and-mouth disease vaccines safer than those currently in use. This strategy may prove useful in the development of vaccines for other viral diseases.
