"All of Arizona’s allocations of both the Pfizer and Moderna vaccines are delayed due to the extreme weather affecting much of the rest of the country, but that doesn’t mean that Arizonans expecting vaccination in the next few days will necessarily see their appointments canceled," ADHS Communications Director Steve Elliott said in an email to reporters.
All sites in Maricopa and Pima counties administering the Pfizer vaccine currently have enough supply to maintain operations, Elliott said. For other sites, the situation is fluid and will depend on each provider’s current supply.
"At this time, there are enough Pfizer doses available for all sites, including state PODs in Maricopa County, to maintain operations without interruption," Elliott said. "These PODs handle a large proportion of vaccination in Maricopa and Pima counties, which are positioned to work with the rigorous storage requirements and large lot sizes of the Pfizer vaccine. Rural counties and some smaller providers in Pima and Maricopa counties administer the Moderna vaccine, which has less-stringent storage requirements."
The federal government has allocated to Arizona 85,800 Pfizer doses and 90,800 Moderna doses, for a total allocation of 176,600 doses expected to be delivered across the state this week, according to ADHS.
"Because shipping notifications go directly to the provider sites, ADHS doesn’t have specific information on when each provider can expect to receive this week’s allocated vaccine doses, "Elliott said. "Our federal partners have advised that Moderna vaccines weren’t shipped Monday due to the weather, though Moderna shipments from the weekend intended for Monday delivery are expected to be delivered today. Pfizer vaccine doses also weren’t shipped Monday, though federal partners have advised that shipments sent over the weekend for Monday or Tuesday delivery should still be delivered."
