In a virus-ravaged city, nearly 400 million vaccine doses are being made — and shipped elsewhere

In a city battered by the coronavirus, one biomedical plant is churning out enough vaccine doses to inoculate every resident hundreds of times over. The lifesaving medicine is brewed in stainless steel vats and bottled at subfreezing temperatures — then loaded into trucks that carry the vaccines hundreds of miles away. Most will never return. At the eastern edge of Baltimore, Emergent BioSolutions is manufacturing almost all of the yet-to-be approved Johnson & Johnson and AstraZeneca coronavirus vaccines for the U.S. population — an anticipated hundreds of millions of doses in the coming months.
