In Health Watch:Federal health officials say the best way to protect yourself from H1N1 and the seasonal flu is to get vaccinated.But for some.. the risk of an allergic reaction could keep them from getting that protection.Karen Brown reports from New York.Tjivi Mbuende has an egg allergy, so he has to avoid some of his favorite foods.Mbuende says, 'cakes, pancakes which I like.'And he may also have to avoid flu shots. that's because the viruses in the H1n1 and seasonal flu vaccines are grown in eggs.Dr. Clifford Bassett says, 'they may develop immediate symptoms of anaphylaxis, which is a generalized allergic reaction: hives, itchy skin, redness, throat tightness.'Whether you can get a flu shot depends on how serious your egg allergy is.Your doctor can help determine that through a blood test. they can also perform a skin test by putting a small dose of vaccine on the skin.. then checking for reaction.Doctors say proper testing is key.. because many people think they have a food allergy when they actually don't.Dr. Bassett says, 'they may have a food intolerance or other problemsIf there's a severe egg allergy and you can't get the vaccine.. you'll need to protect yourself from the flu as best you can. Wash your hands frequently and if you do get sick.. ask your doctor about flu medications like Tamiflu.Tjivi hopes his tests will show he can get the flu vaccine without a problem.Mbuende says, 'When you're down with the flu, it takes a lot of time for you to recover, so that's why I'd like to get it.'And with record numbers already coming down with the flu this season .. it could be a long haul for anyone without protection.
