(Reuters) - The U.S. coronavirus death toll topped 400,000 on Tuesday, according to a Reuters tally, as the country hardest hit by the pandemic struggled to meet the demand for vaccines to stem the spread of infection.

States including Michigan, New Jersey, New York, Oregon, South Carolina and Vermont have shown signs of vaccine supply strain and are asking for more doses of both approved vaccines, one from Pfizer-BioNTech and the other from Moderna.
