Rates turned higher after Moderna, a biotech firm, said that its potential vaccine to prevent Covid-19 delivered a solid immune response in an early-stage human trial among all 45 patients.

Confirmed cases in the U.S. total more than 3.4 million and deaths have surpassed 136,000, according to Johns Hopkins University data.
