COVID-19 vaccine for widespread use in the United States were set to pull out of a Michigan manufacturing plant Sunday, with the shots that are critical to stopping the nation’s coronavirus outbreak destined to reach states a day later.An assembly line of workers began in the early morning hours pulling doses out of a freezer, boxing the vaccine and loading the units onto pallets so they could be placed on trucks at a Pfizer plant in Michigan.
Dry ice, shipping labels and packing tape were on hand as the workers — donning masks, face shields and gloves — put together the packages inside the warehouse.
