The vaccines were due to Texas before Dec. 25, but reached the state earlier this week. Five shipments containing 4,300 doses that had temperature problems were replaced.
The temperature problems identified in those shipments prompted U.S. officials to delay the Moderna deliveries to Texas because of a potential problem with their temperature sensors, Carrie Kroll, vice president of advocacy, quality and public health at the Texas Hospital Association, told Bloomberg.
Moderna’s vaccine must be kept at minus 4 Fahrenheit for shipping.
