ANN ARBOR, Mich. – The first Michigan Medicine front line health care workers at University of Michigan Hospital are now receiving the very first doses of a COVID-19 vaccine. Workers at U of M Hospital were some of the very first to get the initial vaccine shot late Monday. The first doses from Pfizer came rolling into Michigan Medicine on Monday morning. U of M Health System President Dr. David Spahlinger said he got word over the weekend that the vaccines were ready and being shipped. “It was a package of hope,” Spahlinger said.
