T he U.S. Department of Health and Human Services (HHS) said on Tuesday that it will start winding down mRNA vaccine development efforts under a federal health agency focused on developing medical countermeasures to address public health emergencies.

A research project at Emory University is among the 22 grants and contracts that are being cancelled as the U.S. Department of Health and Human Services begins a “coordinated wind-down” of research into mRNA vaccine technology.

Federal agencies have recently issued a barrage of restrictions that could halt construction of solar and wind farms on public and private lands.
