NIH Lifts Funding Pause on Gain-of-Function Research.
Today, the National Institutes of Health announced that it is lifting a funding pause dating back to October 2014 on gain-of-function (GOF) experiments involving influenza, SARS, and MERS viruses. GOF research is important in helping us identify, understand, and develop strategies and effective countermeasures against rapidly evolving pathogens that pose a threat to public health. The funding pause was lifted in response to today’s release of the Department of Health and Human Services Framework for Guiding Funding Decisions about Proposed Research Involving Enhanced Potential Pandemic Pathogens
