Moderna Plans to Ramp Up COVID-19 Vaccine Production by 20% VOA News Drug maker Moderna says it plans to ramp up production of its COVID-19 vaccine by 100 million more doses than what it originally forecast. The Massachusetts-based company said Monday it would produce 600 million doses in 2021. So far, the company says it has supplied 18 million doses of a promised 200 million to the U.S. government. U.S. states have been administering both the Moderna vaccine and a vaccine produced by Pfizer-BioNTech since late last month. Both vaccines are reportedly highly effective in preventing coronavirus infection. According to MarketWatch, Moderna's stock is up 453.0% over the past year. .
