NEW YORK CITY (WABC) -- After a rollout that some officials admit was slow, the push is on to get more people vaccinated against COVID-19 in New York -- and vaccinated quickly. People have started snapping up appointments at the vaccination sites that have opened over the past couple days, and on Wednesday, two more sites are being added to the mix: one in Westchester County and the other at the Javits Center in New York City. The Javits, which functioned as a massive field hospital last spring when New York City was the epicenter of the pandemic, will now serve as a huge vaccine distribution center.
