Michigan is expanding vaccine eligibility to everyone age 50 and over as of March 22 and adding everyone 16 and over as of April 5, Gov. Gretchen Whitmer said Friday. The announcement came a day after President Biden’s prime-time address, in which he directed states to expand eligibility to all adults by May 1.

“Nearly 1 million Michiganders of all races have already been safely vaccinated,” Ms. Whitmer, a Democrat, said in a statement. “I urge all eligible Michiganders to get one of the three Covid-19 vaccines.”

Currently, everyone in Michigan 65 and older is eligible for vaccination, as are people over 50 who have health conditions that would increase their risk of serious complications from Covid-19, including obesity, hypertension or diabetes. On March 22, all adults with such health conditions will also be eligible.

According to a New York Times database, 19 percent of Michiganders have received at least one dose of vaccine and 11 percent have been fully vaccinated, putting the state’s pace roughly at the U.S. average.
