The Michigan Department of Health and Human Services (MDHHS) was notified by McKesson that several shipments of Moderna vaccine shipped on Sunday, Jan. 17, had their temperature reported as going out of range and getting too cold. The cause of this is under investigation by McKesson. Each vaccine shipment is equipped with a temperature monitoring device used to monitor the vaccine temperature while in transport. McKesson is working quickly to repack additional vaccine to ship out as replacement doses for those that may be compromised and the majority of the 21 shipments were resent on Monday night with the rest sent on Tuesday. An additional six shipments were held back to check that there were no issues with the vaccine which may delay scheduled vaccinations at those six vaccine provider sites.
