The United States on Friday administered its 100 millionth Covid-19 vaccine dose since President Biden took office in January, surpassing the Biden administration's goal of administering 100 million vaccine doses within the president's first 100 days by more than a month, in today's bite-sized hospital and health industry news from the District of Columbia, Maryland, and Massachusetts.

• District of Columbia: The United States on Friday administered its 100 millionth Covid-19 vaccine dose since President Biden took office in January, surpassing the Biden administration's goal of administering 100 million vaccine doses within the president's first 100 days more than a month early. Observers said the new milestone reflects the increase in vaccine supply and efficiency from state and local health departments. Biden told reporters on Friday that the United States is now administering an average of 2.5 million vaccine doses per day—up from an average of about 1.3 million doses per day at the beginning of February. Biden suggested his administration "may be able to double" its initial goal and administer 200 million doses within his first 100 days (Chiwaya, NBC News, 3/19; Miller, Associated Press, 3/19; Saric, Axios, 3/19).

• Maryland: Acting CMS Administrator Liz Richter on Wednesday sent letters formally revoking Medicaid work requirements approved in Arkansas and New Hampshire under former President Donald Trump's administration. Richter in the letters wrote that CMS would withdraw the approvals within 30 days, but the states can appeal the agency's decision. An HHS spokesperson told Politico that CMS has only officially rescinded work requirements in two states. However, CMS under the Trump administration approved requests from 13 states to implement Medicaid work requirements (Roubein, Politico, 3/17).

• Massachusetts: Mass General Brigham has named O'Neil Britton as SVP of operations and as associate COO, effective April 19. Britton currently serves as SVP and CMO of Massachusetts General Hospital, a position he's held since 2016. Britton also previously served as chief health information officer for Mass General Brigham when it was known as Partners HealthCare (Gooch, Becker's Hospital Review, 3/17).
