ANCHORAGE, Alaska (AP) — Alaska public health officials say 3,000 doses of the coronavirus vaccine will arrive later than expected because of a winter storm that has ravaged the continental U.S. The state’s immunization program manager, Matt Bobo, said Thursday that some vaccine appointments may be postponed until next week. The doses were supposed to reach 21 different providers. Kelsey Pistotnik, another state vaccine official, says the delay occurred at a somewhat fortuitous time — a part of the month in which the state was already expecting a smaller vaccine shipment. State officials say they have been communicating with officials at the White House and the CDC about the delay.
