Tekla's Omstead: Great promise from 'a new generation' of health care firms

Dan Omstead, chief executive officer at Tekla Capital Management -- which sponsors four health-care oriented closed-end funds -- says that the pandemic proved the promise of health care and biotech companies as it helped vaccine maker Moderna grow from a small form to one of the largest health-care companies in the world, and now he is looking at 'a new generation of companies that are well funded and developing very innovative products against every health-care target you can imagine.'
