(WXYZ) — As concerns grow over the delta variant, Warren Consolidated Schools is the latest - and largest - school district in Michigan to make indoor masking mandatory for students and staff.
Detroit and Ann Arbor Public Schools are also among the minority of districts requiring face coverings.
Joining us to talk about school mask mandates and the FDA approval of the Pfizer COVID-19 vaccine in the 7 UpFront segment is Dr. Matthew Sims, Director of Infectious Disease Research for Beaumont Hospital.

"About 30% of the people who haven't gotten vaccinated yet have said that once it's approved they'll get vaccinated and they've been waiting for the FDA to give their final blessing, so to speak," Sims says. "it's here now, so we'll see how many of those 30% move forward - hopefully, all of them. If we can get that then I think we have a real shot [at herd immunity}. Every little bit helps by protecting more people and preventing more spread."
