Doses from Kansas’ first shipment of a COVID-19 vaccine are arriving in rural Kansas for hospitals to administer to health care workers, though the state expects its second shipment to be smaller than anticipated.

The state health department said Thursday that Kansas received its first full shipment of two doses of the Pfizer vaccine for 23,750 people.

Agency spokeswoman Ashley Jones-Wisner says federal authorities initially told Kansas that it would get a second vaccine shipment of 29,000 doses next week, but the state has since learned it will receive 17,750 doses. She did not elaborate.

The state is expecting a shipment from Moderna in the next week.  A federal advisory committee has approved the Moderna vaccine and now the Food and Drug Administration will consider approving the vaccine for emergency use.

Several states say they have been told to expect far fewer doses of the Pfizer-BioNTech COVID-19 vaccine in its second week of distribution. That’s leading to worries about potential delays in shots for health care workers and long-term care residents. But senior Trump administration officials on Thursday downplayed the risk of delays.

Two officials who spoke to The Associated Press on condition of anonymity are citing a confusion over semantics. Pfizer said its production levels have not changed.

The first U.S. doses of the vaccine were administered Monday. Already this week, hundreds of thousands of people, mostly health care workers, have been vaccinated. The pace is expected to increase next week, assuming Moderna gets federal authorization for its vaccine.
