US President Joe Biden has vowed to accelerate his country's coronavirus vaccination program, while urging people to continue wearing masks.
Biden spoke to reporters at the White House on Monday about his administration's COVID-19 response and the state of vaccinations.
He said, "At least 90 percent of all adults in this country will be eligible to be vaccinated by April the 19th" and that "the final 10 percent will be eligible no later than May 1."
Biden called on local governments and businesses to maintain or reinstate mask mandates.
He said, "The failure to take this virus seriously -- precisely what got us in this mess in the first place -- risks more cases and more deaths."
He said, "As I do my part to accelerate the vaccine distribution and vaccinations, I need the American people to do their part as well. Mask up. Mask up."
Case counts have been rising in some US states, generating fears of a fourth wave of infection.
