Facing a slower-than-hoped coronavirus vaccine rollout, the Trump administration abruptly shifted gears Tuesday to speed the delivery of shots to more people. The move came as cases and deaths surged to alarming new highs. HHS Secretary Alex Azar announced a series of major changes to increase supply of vaccines, extend eligibility to more seniors and provide more locations for people to get shots. Administration officials describing the new policies conveyed a notable sense of urgency. One change will have some teeth to it. Azar said going forward the federal government will base each state’s allocation of vaccines partly on how successful states have been in administering those already provided.
