AMARILLO -- The long-awaited H1N1 vaccine is finally showing up at some local clinics. It's supposed to make you safer, but some kids are getting sick right after they get it. So is the vaccine causing H1N1, or is it just coincidence?

The answer is no. Rather than H1N1, people having adverse reactions to the mist vaccine because it contains a live virus, and the body recognizes that virus as a threat. So, it reacts the only way it knows how: by firing up the body's immune system.

In other words, the aches, fevers, and chills that often show up immediately after the shot isn't the H1N1 flu attacking you, but rather, your body fighting back against what it thinks is an attack. And believe it or not, that's actually a good thing.

"Most people are going to have some sort of side effect to it," says Dr. Walker Adams at Amarillo Urgent Care. "If they're not having even mild side effects, then we kind of are concerned maybe the vaccine is not effective. Maybe the body's not reacting to it."

Dr. Adams says the symptoms normally only last a day or two. The people most at risk are those ages 10 to 49 because they are usually the healthiest.

If you've gotten the H1N1 vaccine and you're feeling some of those symptoms, doctors say the best way to fight it is with something you probably already have in your medicine cabinet: anti-inflammatory meds like Motrin, Ibuprofin, or Advil. The reason? When your body's immune system is reacting to the virus, the symptoms you feel actually come from chemicals. The anti-inflammatory meds block those chemicals from reaching the recepter sites.

Doctors say you shouldn't get the mist form of the H1N1 vaccine if you fall under a few categories: you're *not* between the ages of 10-49, under the age of 2, pregnant, or have respiratory problems or other chronic medical conditions.
