Buoyed by a surge in vaccine shipments, states and cities are rapidly expanding eligibility for COVID-19 shots to teachers, Americans 50 and over and others as the U.S. races to beat back the virus and reopen businesses and schools. Indiana and Michigan will begin vaccinating those 50 and over, while Arizona and Connecticut have thrown open the line to those who are at least 55. Pennsylvania and Wisconsin are reserving the first doses of the new one-shot vaccine from Johnson & Johnson for teachers. And in Detroit, factory workers can get vaccinated starting this week, regardless of age.
