An mRNA Vaccine against SARS-CoV-2

Moderna has completed their Phase I Trial in the U.S. of their mRNA-1273 vaccine. The results are promising. It induced anti–SARS-CoV-2 immune responses in all participants, and no trial-limiting safety concerns were identified. These findings support further development of this vaccine.  The Phase II trial is underway with results expected by late August. At that point, it will move to a Phase III Trial which will test safety and efficacy in much larger populations. NCT04283461.
