Miami Beach started to deliver Moderna’s COVID-19 vaccines to seniors’ apartments on Wednesday in South Beach, as part of a program that aims to vaccinate 300 seniors.

Fire Rescue personnel arrived at Council Towers North with the first dose of the COVID-19 vaccine. They were carrying blue bins and rolling in coolers for some of the dozens of residents at the affordable housing community for seniors.

“We just have got to get it to them because every day they go without it is a day they’re in danger,” said Miami Beach Mayor Dan Gelber.

To start the program, city officials made sure emergency medical technicians received training and moved an industrial freezer into a fire station to store a small supply of the Moderna vaccine.

City Manager Raul Aguila said the city received 60 vials of the Moderna vaccine on Tuesday in addition to “an extremely limited number of vaccines” for homebound seniors. Authorities are choosing who to vaccinate.

“We don’t want to do what we have seen happen, which is tens of thousands of hundreds of thousands of people call and there’s really not enough vaccine to address them,” Gelber said.
