LANSING (AP) — Michigan Republicans on Tuesday advanced a bill that would prohibit state and local health officials from requiring COVID-19 vaccinations for children under age 18 and were poised to also vote to ban governments from mandating vaccine passports.

Neither concept is under consideration in the state. But GOP lawmakers said they want to be proactive.

“While they might not be mandating something, they’re certainly creating a scenario where mandates are being pushed. I just wanted to ensure that that wasn’t going to happen in this space. Parents should be allowed to make the decision on this,” Sen. Lana Theis, of Brighton, said of her legislation that would prevent the use of a state or local emergency order to require coronavirus vaccines for minors. It won Senate approval on a 20-16 party-line vote.

Democrats called the bill needless and noted that if the COVID-19 vaccine were added to the list of immunizations children need to attend school, the state allows for exemptions.
