How the Biden administration can help get the US vaccinated

President-elect Joe Biden says he’s going to ask Americans to cover their faces in public for the first 100 days of his presidency. Urging people to wear masks is entirely reasonable. It’s exactly what people should do to minimize coronavirus infections as vaccination proceeds. Yet after almost a year with no such commonsense guidance from the White House, Biden’s modest request seems almost shocking — a sad commentary on the lack of leadership to this point.
