characterized its mRNA (12). They elucidated the biogenesis and subcellular localization of the M segment proteins involved in viral entry using in vitro transcription/transla-tion and recombinant vaccinia viruses (13 – 16). Antigenic determinants on the G2 glyco-protein were identi ﬁ ed and mapped using recombinant Escherichia coli expression clones (17). Marc ’ s contributions in this area are still cited today in publications on RVFV vaccine development.
