As Putnam County winds up its mass COVID-19 vaccination and testing programs, County Executive MaryEllen Odell thanked the volunteers, medical professionals and businesses who worked together during the pandemic.  Public demand for COVID-19 vaccines and tests plummeted in the past few weeks as the number of Omicron cases and hospitalizations sharply declined. Because of the lack of demand, the Putnam County Department of Health held its last vaccination clinic on Tuesday. The drive-thru rapid tests site run by the county and its partner, Ambulnz, in Carmel will end tomorrow.  At the height of the Omicron surge, 600 to 700 people tested a day. By the start of this month, the number of tests administered dropped to the single digits on some days.
