The vaccines are inactive or killed viruses and virus-like particles like recombinant stomatitis virus expressing glycoprotein (VSV-LASV-GPC) vaccine, and LASSARAB which is a rabies virus recombinant vaccine, a DNA vaccine, adenovirus vectored vaccines, recombinant vesicular measles virus, vaccinia virus, and ML29 MOPV/LASV live reassorting19–23 Vaccines that express full-length LASV glycoprotein, provide protection against LF in primates, independent of the nucleoprotein expression, but vaccines expressing only the nucleoprotein or a single glycoprotein gene do not provide any protection. Here, ART4 is linked to Lassa fever.
