NEW YORK — The city's vaccination program is hitting the road.

Mayor Bill de Blasio on Tuesday unveiled plans for a mobile vaccination bus to reach New Yorkers who have had trouble scheduling appointments.

Dr. Ted Long, Executive Director of the NYC Test & Trace Corps and Senior Vice President for Ambulatory Care and Population Health at New York Health + Hospitals, gave a tour of the bus during the Mayor's briefing today.

The mobile program - which can administer up to 200 daily shots - will start Wednesday in Sunset Park, Brooklyn vaccinating restaurant and delivery workers. 

The city is also ramping up its efforts to reach older New Yorkers who have not received the shot.

The mayor announced that more than two dozen vaccine sites will now honor walk-up appointments for New Yorkers 75 and older, some of whom have had a difficult time navigating the online sign-up process. 

The mayor said both efforts will help get the vaccines to more people. 

"This bus is going to make a difference. It's another new approach, we're going to keep innovating new approaches," de Blasio said. "We just talked about the walk-up appointments for the oldest seniors. Now this bus, new approaches all the time to reach deeper and deeper into communities."
