LANSING, Mich. – The Centers for Disease Control and Prevention has prioritized frontline health care workers and those 65 years of age and older to receive the COVID-19 vaccine first. Gretchen Whitmer’s added use of social vulnerability as part of her vaccine distribution calculations has led to concerns about fairness among some -- especially among lawmakers, since thousands of Michiganders struggling to schedule vaccination appointments are calling legislators daily. But state Sen. Sylvia Santana (D-Detroit) says it is a life and death issue, and social vulnerability is included in the eligibility criteria for a good reason. “Blacks are 1.9 times more likely to die, Hispanic Americans are 2.3 times more likely to die and Native Americans are 2.4 times more likely to die,” Santana said on the Senate Floor Thursday. Duggan also sparred with Macomb County Executive Mark Hackel over vaccine dose distribution.
