Rebecca Bredow is a mother in Michigan, who refuses to let her son be vaccinated, in violation of an agreement with her ex-husband, the boy's father. Her refusal to comply with a court ordering her to do so is about to land her in jail.
The NVIC claims that parents have been jailed before for refusing their child to be vaccinated.
Barbara Loe Fisher, president of the non-profit National Vaccine Information Center, told the BBC this is not the first time a parent has been jailed for refusing to vaccinate a child.
Has that happened before the current case of Rebecca Bredow?
Have parents in the USA been jailed for refusing their child(ren) to be vaccinated?
The NVIC is an organisation in the USA, calling itself "national" so assuming that at least one of the four words in their name is correct, it's not unreasonable to assume they're referring to parents in the USA, even though they don't claim this explicitly.
One could argue that the mother was/is/will be jailed for refusing to comply with a court order rather than for refusing to vaccinate, but the court order was for her to have her kid vaccinated, so it's a reasonable summary.
I've had to alert a Dutch news agency to the fact that the NVIC is not a governmental agency, but an anti-vaccine lobby group. They've now adjusted their news article, but still repeat this claim.
