Columbia University is calling on the community to make an appointment to donate blood at the Power to Save Lives Blood Drive at Columbia on September 4th. Before COVID-19, mobile blood drives hosted by high schools, colleges, businesses and other organizations made up about 75% of the region’s incoming blood supply, but the number of blood drives has dropped by two-thirds this year due to the pandemic. The upcoming school year presents new and unprecedented challenges. Blood donations are typically lower during the summer and the return to school usually helps make up the difference and stabilize the blood supply. In the past, school and college drives have resulted in 75,000 blood donations during each school year.
