Her father, Jim, says she has been in remission for a year but that her health is still fragile. He says he's having a hard time finding a place where she can get the H1N1 vaccine because some of the places that offered them have run out.
Williams says he fears if his daughter is not protected, her health could be in jeopardy.
"We're just devastated because we don't know. Her immune system is already low and god forbid she ever got the virus. God could only imagine what would happen to her," said Jim Williams, father.
