evidence: Moderna's COVID-19 vaccine is expected to become the second to get the Food and Drug Administration's green light. A decision could come within days. [...] Vice President Mike Pence traveled to Bloomington, Ind., on Tuesday to tour Catalent, a contract manufacturing facility expected to help produce millions of Moderna coronavirus vaccines in the coming weeks and months. Catalent is probably the biggest drugmaker you've never heard of. It has dozens of factories around the world and makes more than 70 billion doses of all kinds of drugs each year. The company's facility in Pence's home state is working with Moderna on filling vials with the vaccine and preparing them for distribution. [...] Catalent is on track to manufacture and package 20 million doses of Moderna's vaccine candidate by the end of this month, and the facility in Bloomington, IN, is ramping up production to supply another 100 million doses in the first quarter of 2021. Globally, the company is working on more than 75 Covid-19-related programs including antivirals, vaccines and treatments."
