Recombinant vesicular stomatitis vaccine against Nipah virus has a favorable safety profile: Model for assessment of live vaccines with neurotropic potential.

Nipah virus (NiV) disease is a bat-borne zoonosis responsible for outbreaks with high lethality and is a priority for vaccine development. With funding from the Coalition of Epidemic Preparedness Innovations (CEPI), we are developing a chimeric vaccine (PHV02) composed of recombinant vesicular stomatitis virus (VSV) expressing the envelope glycoproteins of both Ebola virus (EBOV) and NiV. The EBOV glycoprotein (GP) mediates fusion and viral entry and the NiV attachment glycoprotein (G) is a ligand for cell receptors, and stimulates neutralizing antibody, the putative mediator of protection against NiV.

Exposure to environmentally-relevant concentrations of hexavalent chromium does not induce ovarian toxicity in mice.

Exposure to high concentrations of hexavalent chromium [Cr(VI)] in drinking water (≥250 ppm) is reported to decrease ovarian follicle counts and increase follicular atresia in mice. To assess effects at lower concentrations, herein we exposed B6C3F1 mice to 0.1-150 ppm Cr(VI) in drinking water for 90 days in a GLP-compliant study.
