The Florida Department of Health in Miami-Dade County released a limited number of COVID-19 vaccine appointments Friday that filled up minutes after they were available.
The reservations, for seniors ages 65 and older by appointment only, were made available at 4 p.m. Friday through the county's scheduling tool at miamidade.gov/vaccine, miamidade.gov/vacuna and miamidade.gov/vaksen.
All slots were filled within about 30 minutes, officials said.
"Demand for vaccines is currently much greater than existing supply," the Department of Health said in a statement.
Appointments will reopen once additional vaccines are received.
The vaccine being offered requires a second dose, and at the time of vaccination, individuals will receive information regarding the second dose.
After receiving the vaccine, individuals will be required to remain seated for 15-30 minutes for medical monitoring.
