NASHVILLE, Tenn. -- It's been the advice we've heard for months: Get the H1N1 vaccine and get it soon.

But a local mother has concerns about its effectiveness, after she followed the recommendations and her son still developed the disease.

"Just because your children have had the H1N1 shot, does not mean you're protected," said Reynolds. "Your children and your family can still get it."

In late October, Sandy Reynolds took her 2-year-old, Zach, to a local vaccine clinic, then followed the recommendations with a follow-up shot earlier this month.

The drug-maker, though, later recalled the second one, over concerns it wasn't strong enough.

"When he started running a fever that's the first thing I thought of and that's why I took him to the doctor to get him tested for the H1N1," said Reynolds.

But according to the Centers for Disease Control, it's not likely the recalled shot played a part. Announcing the recall of 800,000 vaccines last week, scientists said there were no safety concerns.

"Kinda upsetting," said Reynolds. "I've done everything that I could to try to keep him from getting sick. I'm not going to really say I point the blame at anybody, but it's still very upsetting that they tell you that everybody should get the shot, but you still have to be concerned about getting the H1N1."

Dr. Tim Jones, the Tennessee State Epidemiologist, told Channel 4 News it's the first time he's heard of anyone developing H1N1 after receiving the vaccine. But he also said no vaccine is perfect, it takes time to become fully effective and some recipients' immune systems don't react as well as others.

Right now, Zach Reynolds has a high fever and may have to return to the doctor's office tomorrow morning. His parents are taking their own precautions, including medication, to try to reduce their chances of contracting the disease.
