The Michigan Department of Health and Human Services (MDHHS) Division of Immunization and the Flu Advisory Board have created an Influenza Vaccine Exchange Network (IVEN), a centralized location where providers of influenza vaccine can share information about their influenza vaccine inventory.  IVEN  will facilitate vaccine redistribution, should shortages or misdistribution occur. IVEN can be used by licensed physicians, their staff, local health departments, pharmacy staff, nursing homes, hospitals, and other health care or vaccine providers to post and search for surplus or needed influenza vaccine. IVEN is only accessible to sites that are registered to use MCIR.
