How to deal with antivaxer relatives?

Heather • Mother to one boy, three babies with wings, pregnant for the fifth time
My husband and I got the TDAP vaccine and asked our immediate family members (parents, siblings) to get it too since they'll all be spending a lot of time around the baby. Unfortunately, my mother in law is an antivaxer and very skeptical of medicine and doctors in general. Her naturopath of course told her the vaccine would be bad for her and she's basically refusing to get it. She wants to use a homeopathic remedy instead. We believe, as do doctors and anyone who understands and values science, that vaccines are safe and extremely important. How should we deal with this? Has anyone else run into this problem?
