High-level executives are quitting in droves
"At least a dozen highly placed executives have quit in the past four years, including heads of finance, technology, manufacturing, and science. In just the past 12 months, respected leaders of Moderna's cancer and rare disease programs both resigned."
Most notable among the resignations was the highly respected and veteran chief scientific officer, Joseph Bolen, who had previously led another Big Pharma company to FDA approval for a hugely successful cancer drug. "'No scientist in his right mind would leave that job unless there was something wrong with the science or the personnel,' said a person close to the company at the time."
