Developed with the National Institutes of Health, Moderna’s shot, like the one produced by Pfizer Inc. and BioNTech SE that was cleared last week, is based on messenger RNA technology that previously hadn’t been used in vaccines. For Moderna, whose stock-market ticker symbol is ‘MRNA,’ it is also the first product from the company to be cleared by regulators for use. An application for full approval is expected next year.
