LOUISVILLE, Ky. (WDRB) -- Louisville's mass vaccination site on Wednesday began giving out the Pfizer-BioNTech vaccine for the first time since it started administering shots. 

Health officials said the transition stems from a change in the vaccine allocation that Louisville's health department gets from the state. People who have already received their first dose of the Moderna vaccine at Broadbent Arena will receive a Moderna booster.

Medical officials said the site at Broadbent Arena is better equipped to handle the regulatory requirements of the Pfizer vaccine than sites in rural counties. The Pfizer vaccine has to be stored at ultra-cold temperatures and is only good for two hours once it has thawed.
