It's a parent's nightmare: Your child is walking one day and then one day later, suddenly cannot walk. That's what happened to one Shreveport little girl.

5-year old Hannah Pham is paralyzed from the waist down.

"I just want to run with my friends and have a race" she says while strapped into a wheelchair.

Hannah wears braces on her legs and back. Her parents are heartbroken.

"If I could take it, I'd take it for her" says Nam Pham, Hannah father. He starts crying.

"I just feel so bad" says Lily Pham, Hannah's mother.

Boxes are stacked in the entry way, full of supplies for Hannah. The 5-year old wears diapers because she cannot control herself.

She rolls around in special wheelchairs.

But she hasn't always been like this.

"I think it's from the H1N1 flu shot. She was born healthy, nothing wrong with her" says her father.

Her parents say on December 2, 2009 she was given the vaccination at school. One month and five days later, everything changed.

"I tried to stand up and I couldn't" says Hannah.

That began the visits to the hospital. Her medical records indicate dozens of tests, MRIs and x-rays, 102-degree fevers, urinary tract infections, and atrophy in her legs.

Hannah has been to several hospitals, seeing different specialists.

Records NBC 6 News obtained from the Louisiana Department of Health and Hospitals show Hannah was diagnosed with a history of Transverse Myelitis.

The National Institutes of Health website states they are uncertain of the exact cause of the neurological disease, but it may result from viral infections, abnormal immune reactions, insufficient blood flow through the spinal cord or as a complication from some vaccinations.

"Studies were done especially with H1N1 vaccine to look for rare side effects. So the evidence so far is that it is not associated to any significant degree to rare side effects such as neurological diseases" says Dr. Joseph Bocchini, the LSU Health Sciences Center Pediatrics Department Chairman. He also specializes in pediatric infectious diseases.

"There are people who have events that occur following a vaccination that may or may not be related to the vaccination. That you just got the vaccine and something's going to happen. Whether you got the vaccine or not" he says.

"I don't think anyone has the answer for it. They say, give it time, give it time. But when?" Hannah's father asks.

No effective cure exists for the disorder according to the National Institutes of Health and that is no comfort to Hannah or her parents.

"I would hope that she would be able to walk back again. That's what I want, nothing else" says Nam.

The family continues hoping and praying for a miracle.

Hannah goes to acupuncture in Longview, Texas three times a week. She also undergoes physical and occupational therapy.

Her parents spend thousands of dollars on her care. If you'd like to help, a Capitol One bank account has been set up to help the family with medical expenses; account number #5732404947. Nam Pham can be contacted at (318) 210-8820.

The National Institute of Neurological Disorders and Stroke says 1400 new cases of Transverse Myelitis are diagnosed every year in the U.S. and estimates 33,000 have some type of disability from the disorder.

This year's flu vaccine will include three strains of the influenza virus. Type 1, type b, and the H1N1 vaccine. Health officials believe the H1N1 strain will be the predominant flu spread this year. The CDC reports 30,000 people die every year from the flu or flu complications.
