Abstract:

Puumala virus PUUV is a causative agent of hemorrhagic fever with renal syndrome HFRS. Although PUUV-associated HFRS does not result in high case-fatality rates, the social and economic impact is considerable. There is no licensed vaccine or specific therapeutic to prevent or treat HFRS. Here we report the synthesis of a codon-optimized, full-lengthMsegment open reading frame and its cloning into a DNA vaccine vector to produce the plasmid pWRGPUU-Ms2. pWRGPUU-Ms2 delivered by gene gun produced high-titer neutralizing antibodies in hamsters and nonhuman primates. Vaccination with pWRG PUU-Ms2 protected hamsters against infection with PUUV but not against infection by related HFRS-associated hantaviruses. Unexpectedly, vaccination protected hamsters in a lethal disease model of Andes virus ANDV in the absence of ANDV crossneutralizing antibodies. This is the first evidence that an experimental DNA vaccine for HFRS can provide protection in a hantavirus lethal disease model.
