U.S. government scientists have begun efforts to manufacture a strain of the novel coronavirus that could be used in human challenge trials of vaccines, a controversial type of study in which healthy volunteers would be vaccinated and then intentionally infected with the virus, Reuters has learned.

“Should there be a need for human challenge studies to fully assess candidate vaccines or therapeutics for SARS-CoV-2, NIAID has begun investigations of the technical and ethical considerations of conducting human challenge studies,” the agency statement said.

That includes efforts to manufacture a suitable SARS-CoV-2 strain, draft a clinical protocol and identify resources that would be required to conduct such studies.
