Flu vaccine and seizure meds need advice or opinion

Perie, my husband and I have a discussion about our daughter having a flu vaccine, question is it a good idea to have a flu vaccine or not while taking seizure meds? I'm so worried this is her first year taking seizure meds and flu vaccine, also which one is good flu shot or in the nose. She want it in her nose, is there any thing that I need to watch for. Her doctor said it's ok  just need every one advice and opinion thanks.
