How close is Florida to herd immunity? Because most people are unvaccinated, COVID-19 cases could spike again and they have not impacted hospitalization rates, according to an expert. Author: Renata Di Gregorio Updated: 7:32 AM EST March 9, 2021 JACKSONVILLE, Fla — For the first time since opening, the new Gateway Mall vaccination site gave close to its number of available doses Monday. Over the weekend the new FEMA sites were giving less than half the number of vaccines they can do. Most people are still unvaccinated and because of that, an epidemiologist at UF Health Jacksonville says the lower hospitalization rates seem to be just another plateau of cases and have nothing to do with the vaccine.
