Those sites are: New Rochelle Public Library, 1 Library Plaza from Thursday, April 1 through 5 p.m. on Saturday, April 3; Greenburgh Neighborhood Central, 295 Knollwood Road from 9 a.m. to 5 p.m. on Saturday, April 3. They are among 18 new community-based pop-up vaccination sites coming online at churches, community centers, public housing complexes, and cultural centers in downstate New York to “bolster the state’s commitment to ensuring fairness and equity in the vaccine distribution process.”
