"Shipping partners are working to deliver vaccine where possible, contingent on local conditions, but the adverse weather is expected to continue to impact shipments out of the FedEx facility in Memphis, Tenn., as well as the UPS facility in Louisville, Ken., which serve as vaccine shipping hubs for multiple states," CDC spokesperson Kristen Nordlund said in a statement.
"The two biggest shippers involved here -- UPS and FedEx -- have major either hubs or warehouses down in the South, in Memphis and in other areas. So, we do expect there could be a blip in delivery of vaccine that is weather-related specifically," Freeman said. "We have contingency planning in place related to the movement of vaccines, which have priority status within our network, and are working directly with our customers to help ensure their safe transport and delivery," the statement said.
"We have extensive contingency plans for storms that help us to keep goods moving when roadways are impassable or airports are closed because of severe weather."
