It is true that some people outgrow their food allergies (especially children) but this is less likely with allergies to nuts and fish.

There isn't a cure for food allergy so the only way to prevent a reaction is to avoid the food you're allergic to.

If you have a mild food allergy, it may be possible to treat this with antihistamines. However, it's important that you only take medicines for your allergy on the advice of your doctor. Always read the patient information leaflet that comes with your medicine and if you have any questions, ask your pharmacist for advice.

If you have a severe food allergy, you may be at risk of anaphylaxis and will need to take certain precautions. Despite reading menus and ingredients lists carefully, it's easy to eat a problem food by accident. Even a tiny amount of a problem food can trigger a severe reaction.

Ask your doctor for advice about what to do if you have an allergic reaction.
Let your family, friends and work colleagues know about your allergy, and how they can help you in the event of an emergency. Wear a bracelet or carry a card that gives details about your allergy. Carry a pre-loaded adrenaline syringe. Adrenaline is a hormone (a chemical that occurs naturally in your body) that relaxes muscles and so helps to reduce any swelling and make breathing easier. Single doses of adrenaline are available in the form of an EpiPen or AnaPen that consist of a sterile syringe of adrenaline that is ready to be used in an emergency. You will need to go to hospital immediately if you have anaphylaxis, even if using adrenaline has helped to reduce the reaction.

If your child has a severe allergy, you must make sure that all their carers and teachers have the information to react correctly in an emergency.

If you have a food allergy, it's important to check the packaging of foods carefully to find out if they contain what you're allergic to. There are laws that food manufacturers have to work to that mean that all pre-packed food sold in the UK and the European Union must say on the label whether it contains an allergen, such as eggs or nuts. Attempts are being made to extend this to other foods that aren't pre-packed.

If you're allergic to eggs, you won't be able to have the vaccine for yellow fever. Your GP is also likely to advise you not to have the flu vaccine

Your are right, one of my cousins is allergic to Eggs and he dint had this vaccine. do this cause any bad effects on his health?

I think that with any allergy it is always important that you let people know about it i=f yo are in any situation where it might be an issue. Having an allergy to egg is a problem because there is egg in lots of things that don't look like they obviously do contain egg, life cake or pancakes. I imagine that you cousin is used to being careful with what they eat and what they allow to be down to them. It might be best to get one of those medalert bracelets to say that there is an allergy to eggs.
