Lansing, MI — State health officials say Michigan has capacity to vaccinate up to 80,000 people a day, But they say the supply of COVID-19 doses remains limited, though it's been higher in recent weeks. They said Friday that their goal is to ensure no one has to travel more than 20 minutes to a vaccination site in the pandemic. A priority is allocating doses to areas based on factors such as poverty, lack of transportation and crowded housing. That correlates to places hard hit when the pandemic struck last spring, such as Detroit.
