"The federal biological mass-spray program tied to DEFUSE did not end with the rejected proposal or with COVID.

USGS and PARC were developing automatic mass delivery before DEFUSE.

DEFUSE proposed repurposing the capability for aerosol and automated delivery of biological formulations, while PARC identified potential application to large-area inoculation of “animals/humans.”

USDA separately authorized spraying a raccoon-poxvirus-vector bat vaccine before COVID.

USGS then paid PARC to “DEVELOP&TEST SPRAY DEVICES” during COVID while conducting vaccine studies involving spray-device application."
