WASHINGTON – Medicare will cover the yet-to-be approved coronavirus vaccine free for older people under a policy change expected to be announced shortly, a senior Trump administration official said Tuesday.The coming announcement from the Centers for Medicare and Medicaid Services aims to align the time-consuming process for securing Medicare coverage of a new vaccine, drug or treatment with the rapid campaign to have a coronavirus vaccine ready for initial distribution once it is ready, possibly as early as the end of the year.It's questionable under normal circumstances if Medicare can pay for a drug that receives emergency use authorization from the Food and Drug Administration, as expected for the eventual coronavirus vaccine.
