Vaccine shipments start
Federal officials on Saturday said 145 distribution sites are expected to receive the vaccine on Monday, another 425 sites will get the shot Tuesday and the remaining 66 sites on Wednesday
Roughly 2.9 million doses are going out in the first shipments
Officials caution that the initial supply is extremely limited and will only go to people at highest risk. The CDC recommended health care workers and long-term care facility residents get the vaccine first, though states and territories will have final say over who they choose to prioritize.
