#fyiSI: I made a COVID-19 vaccine appointment, do I need to keep it now that walk-ups are permitted? Today 6:30 AM STATEN ISLAND, N.Y. -- Last week the city lifted all eligibility requirements at city Department of Health (DOH)-run coronavirus (COVID-19) vaccination sites across the five boroughs. As of Friday, April 23, city residents aged 16 and older can get vaccinated without an appointment at any site administering Pfizer and those 18 and older can get vaccinated at any site administering Modera. “Life in this city is coming back so we want to make it simple,” de Blasio said. “Convenience matters to New Yorkers.”
