LOUISVILLE, Ky. — More than 66,000 doses of the COVID-19 vaccine have been administered in the Louisville Metro area, health leaders said Friday.

Friday marked the fourth week of operation for Broadbent Arena's drive-thru mass vaccination site.

"We're making good progress every week, but if we had more supply, obviously, we could do a lot more," said Louisville Mayor Greg Fischer. "We could have more shifts going on here."

JCPS elementary school educators who got their first shots this week were among more than 16,000 people who have come to Broadbent Arena to receive the vaccine.

Brittany Jones, a literacy coach at Chancey Elementary, explained why she signed up for the shot.

"Our teachers at Chancey are amazing, our students, our families, and we're ready to get back to them," she said. "That's why the decision to get the vaccination was so easy for me, because it was that shot of hope that we've been waiting months for."

JCPS bus driver Patrick Salyer was in line for his first dose Friday.

"I'm very, very happy about it," he said. "Obviously, I want life to get back to normal."

Fischer said he was optimistic about President Biden's announcement that states would receive a 16% increase in vaccine supply, but he cautioned that Louisville was still at the beginning of the vaccination process.

"We want to communicate on what's happening and give people hope that a vaccine's going to be coming to everybody in the city that wants one, but it's going to take months," he said.

Middle and high school teachers and people getting their second doses of the vaccine are expected at Broadbent Arena next week, leaders said.
