Nanny with epilepsy?

We found a great nanny and she’s been coming for a few weeks now. We called references and she also babysits for our neighbor. I googled her name randomly yesterday and saw that a few days ago a post was made saying she has epilepsy and is getting a service dog in a few years (she bought him and he’s being trained now). My husband is asking me if I’m okay leaving our kids (2 years and 6 months) with her home alone. I really have no idea and am wondering what other moms think. She does not drive.
