Viral Gain of Function Research Moratorium Act This bill prohibits the award of federal research grants to institutions of higher education or research institutes that conduct gain-of-function research. Gain-of-function research refers to any research that (1) may be reasonably anticipated to confer attributes to influenza, MERS, or SARS viruses such that the virus would have enhanced pathogenicity or transmissibility in an organism; or (2) involves the enhancement of potential pandemic pathogens or related risky research with potentially dangerous pathogens.
