evidence: The tornado that ripped through a major Pfizer pharmaceutical plant in North Carolina on Wednesday "almost completely destroyed" the plant’s warehouse, which stored raw materials, packaging supplies and finished medications awaiting release to hospitals across the United States, Pfizer CEO Albert Bourla said during a press conference on Friday. [...] Assessing the damage will be difficult, according to Pfizer, as only a small number of people have limited access to the facility due to hazards still present from the tornado. [...] Pfizer said in a statement that it is moving what it can to nearby sites for storage. The facility will remain closed while the damage continues to be assessed.
