DENVER (KDVR) — Severe winter weather impacting much of the country has delayed COVID-19 vaccine shipments bound for Colorado, the state announced Tuesday afternoon.

According to the Colorado Department of Public Health and Environment (CDPHE), storms are impacting a vaccine distribution hub in Tennessee, resulting in the delay of 133,000 vaccines that were expected to arrive in Colorado Tuesday through Thursday.

The CDPHE says it is “working with Colorado’s health care providers and local public health agencies across the state to make adjustments over the coming days to make sure appointments and clinics do not need to be canceled.” 

According to the CDPHE, due to the holiday weekend, the state requested and received doses on Friday that were originally scheduled to be administered this week.

“This decision helps us have enough on hand to work with providers to move doses around to prevent cancelations,” the CDPHE said.

Colorado was one of several states affected by the delay.

Brigadier General Scott Sherman, who is in charge of the state’s distribution, 45,000 of the delayed doses shipped Tuesday and the remaining doses will ship Wednesday.

All of the impacted shipments were second doses of the Pfizer vaccine, Sherman said.

“That was really a problem because some hospitals were waiting on second doses. They were able to work between each other and get that taken care of and make sure we had enough on hand,” he said.

Sherman said all of the delayed doses should be in Colorado by Friday.

“During last week, we were able to get some extra doses. We were able to get 40,000 Moderna and 25,000 Pfizer beforehand, so that did help,” he said.
