At long last, the day has arrived: One year, one month, and four days after the first coronavirus case was reported in Florida, the COVID-19 vaccine is available for all state residents age 16 and older. Starting this week, those residents can begin to make appointments or try their luck at a first-come, first-serve site, regardless of their medical history or occupation. Previously, the shots were only available to residents over 40, people with high-risk health conditions, and workers in certain occupations, like education or policing. If you're new to all of this, there are a few things to know upfront. First, you're not limited to vaccine sites in your city or county — Florida residents can snag an appointment at any vaccination site in the state. The Pfizer shot is available to teens as young as 16; for the Moderna or Johnson & Johnson vaccines, you must be at least 18. You probably already know, but the Pfizer and Moderna vaccines require two shots a few weeks apart, while the Johnson & Johnson vaccine is administered in a single dose.
