Michigan’s 8,900 doses of Moderna vaccine that got too cold during transport can be used, state says

Michigan’s 8,900 doses of Moderna vaccine that too cold during transport were deemed acceptable, state officials said.

January 19, Michigan Department of Health and Human Services announced that several shipments of the Moderna vaccine that were sent out on January 17 have left the recommended temperature range.

Healthcare firm McKesson informed the MDHHS of the issue. McKesson has conducted an internal investigation and determined the cause of the problem with those 21 shipments, officials said.

Based on the information gathered during this investigation, Moderna decided that the doses were still viable on arrival.

The doses are still usable because they were either stored in quarantine at minus -20 degrees Celsius or were stored in quarantine at 2-8 degrees Celsius and placed in refrigerated storage within 30 days, depending on the state.

The Centers for Disease Control and Prevention has indicated that the doses can still be used to vaccinate Michiganders.

“We are pleased to be able to use these vaccines to protect Michiganders from the virus as we work to achieve our goal of vaccinating 70% of Michiganders over 16 years of age as quickly as possible with the safe and effective COVID-19 vaccine,” said said Dr Joneigh Khaldun, MDHHS medical director. “These safeguards are put in place to ensure the integrity of the vaccine and, based on the investigation that was conducted, these vaccines can now be used.”

Vaccines are shipped to vaccine suppliers statewide by manufacturers and distributors, not the MDHHS. Each shipment is equipped with a temperature monitoring device during transport.
