If it helps you to make an informed decision, I developed sensory and motor peripheral neuropathy after the Covid vaccines. My neurological symptoms started within 2 weeks. My ANA titer peaked at the same time my neurological symptoms peaked. I had never had problems with autoimmunity before. There are 4300 other patients like me in a Facebook group for those with neurological injuries due to the vaccines. After my extensive research prompted by my vaccine reaction, I believe your doctor's suspicion that your daughter could have a vaccine injury is highly credible.
