Health-care companies ticked down as the leaders of the race to get a Covid-19 vaccine gave back some of their recent gains.

Pfizer and BioNTech, who are partners on the vaccine that appears closest to completing trials, fell Wednesday. Shares of Moderna, another vaccine developer, recouped some of their recent losses.

"We expect the Pfizer vaccine, and perhaps other vaccine candidates, will receive emergency use authorization by January, and sufficient doses will be available to vaccinate the U.S. population during the first-half of 2021," said strategists at brokerage Goldman Sachs Group, in a note to clients.

Photography concern Eastman Kodak said five former executives were able to collect millions of dollars by selling stock options they didn't own, an admission that is set to add to the scrutiny the company faces over the circumstances surrounding a halted U.S. loan intended for production of medical equipment.
