Hharvard biology professor and serial entrepreneur Timothy Springer saw promise in a fledgling biotech firm a decade ago and he put about $5 million into the company as an early investment. Now, a decade later, that initial investment is worth nearly $870 million. Now, primarily as a result of that bet — on a Cambridge, Massachusetts company called Moderna — he’s a billionaire. Shares of Moderna, which has a Covid-19 vaccine currently in human clinical trials, rose more than 12% this week, bucking the overall drop in the stock market. That surge has turned Springer into a billionaire: Forbes estimates he is now worth $1 billion based on his 3.5% equity stake in Moderna and stakes in three smaller biotech outfits. Some healthcare billionaires’ fortunes have risen by billions of dollars since the WHO declared a global pandemic on March 11. The biotech rally could keep gathering pace as the public eagerly awaits new developments in the fight against Covid-19. source
