Experimental COVID-19 mRNA vaccine formulation remains stable after a year at room temperature

MIT News reports that researchers used an AI algorithm to select ingredients for the particles that protect and deliver mRNA. They vacuum-dried experimental COVID-19 vaccine doses, then stored them for a year at room temperature or two months at 98°F. In mice, the stored doses produced immune responses comparable to vaccines using particles similar to Moderna’s. The team also tested the formulation in vaccine-delivering microneedle patches.
