Moderna co-founder is a billionaire again at $1.7 billion—he once turned down 20 high-paid jobs
Moderna co-founder Robert Langer's net worth doubled to $1.7 billion following positive Phase 3 trial results for a cancer vaccine developed with Merck, boosting Moderna's stock over 100%. Langer's stake, valued at 3%, surged from $730 million to over $1 billion. This marks his second time as a billionaire, after Moderna's COVID-19 vaccine success in 2020.
