Community Healthcare Network (CHN), a network of 14 Federally Qualified Health Centers in New York City, and Stop the Spread (STS), a catalytic organization that has corralled private industry partners for Covid-19 response programs, partnered to increase vaccine uptake in New York City neighborhoods with low vaccination rates.

At the onset of the COVID-19 outbreak in early March, CHN began testing qualifying patients at all 12 of its community health centers located in Queens, Brooklyn, Manhattan and the Bronx. At the direction of the New York City Department of Health and Mental Hygiene, all community based centers in New York City suspended testing on March 20th.
