Protesters showed up outside a Michigan courtroom Wednesday as a mom was jailed for refusing to obey court orders mandating she vaccinate her nine-year-old son.

Detroit resident Rebecca Bredow will spend a week in jail for disobeying an Oakland County circuit court judge's decree to get her son up-to-date on vaccinations.

Judge Karen McDonald wrote that Bredow had signed an agreement to immunize her son in November 2016, and that no appeal of the order, which stemmed from a custody battle, was ever received.

Bredow indicated last week she had no plans to follow the judge's orders, and insisted she'd sooner go to jail than vaccinate her son.

"I would rather sit behind bars standing up for what I believe in, than giving in to something I strongly don't believe in," Bredow told WXYZ a week ago.

Bredow says she originally agreed with her ex-husband to space out vaccines, but grew more concerned after researching and learning multiple shots would be administered at once.

"It wasn't until they started grouping them together that I backed off of doing vaccines," Bredow said.

"These are combo shots that could be up to 40 vaccines at once," Bredow told CBS Detroit. "So, I mean that's pretty serious. That's a lot of vaccines to inject into your child at once."
