Eating<unk>  The cause is typically the eating of<unk> s or foods that contain<unk> s. Briefly, the immune system over-reacts to proteins found in<unk> s. This allergic reaction may be triggered by small amounts of<unk> , even<unk>  incorporated into cooked foods, such as cake. People with an allergy to chicken<unk> s may also be reactive to goose, duck, or turkey<unk> s. Vaccines Influenza vaccines are created by injecting a live virus into fertilized chicken<unk> s. The viruses are harvested, killed and purified, but a residual amount of<unk>  white protein remains. Each year, vaccines are created to provide protection against the flu viruses expected to be prevalent in the upcoming cold weather months. For the 2017-2018 flu season, the vaccines are described as IIV3 and IIV4 for resistance to the expected three or four viruses. For adults ages 18 and older there is also an option to receive recombinant flu vaccines (RIV3 or RIV4) which are grown on mammalian cell cultures instead of in<unk> s, and so are no risk for people with severe<unk> . Recommendations are that for people with a history of mild<unk>  should receive any IIV or RIV vaccine. People with a more severe allergic reaction may also receive any IIV or RIV, but in an inpatient or outpatient medical setting, administered by a healthcare provider. People with a known severe allergic reaction to influenza vaccine (which could be<unk>  protein or the gelatin or the neomycin components of the vaccine) should not receive a flu vaccine. Each year the American Academy of Pediatrics (AAP) publishes recommendations for prevention and control of influenza in children. In the 2016-2017 guidelines a change was made, that children with a history of<unk>  may receive the IIV3 or IIV4 vaccine without special precautions. It did, however, state that "Standard vaccination practice should include the ability to respond to acute hypersensitivity reactions." Prior to this, AAP recommended precautions based on<unk>  history: if no history, immunize; if a history of mild reaction, i.e., hives, immunize in a medical setting with healthcare professionals and resuscitative equipment available; if a history of severe reactions, refer to an allergist. The measles and mumps parts of the "MMR vaccine" (for measles, mumps, and rubella) are cultured on chick embryo cell culture and contain trace amounts of<unk>  protein. The amount of<unk>  protein is lower than in influenza vaccines and the risk of an allergic reaction is much lower. One guideline stated that all infants and children should get the two MMR vaccinations, mentioning that "Studies on large numbers of<unk> -allergic children show there is no increased risk of severe allergic reactions to the vaccines." Another guideline recommended that if a child has a known medical history of severe anaphylaxis reaction to<unk> s, then the vaccination should be done in a hospital center, and the child be kept for observation for 60 minutes before being allowed to leave. The second guideline also stated that if there was a severe reaction to the first vaccination - which could have been to<unk>  protein or the gelatin and neomycin components of the vaccine - the second is contraindicated. Exercise as a contributing factor There is a condition called food-dependent, exercise-induced anaphylaxis (FDEIAn). Exercise can trigger hives and more severe symptoms of an allergic reaction. For some people with this condition, exercise alone is not sufficient, nor consumption of a food to which they are mildly allergic sufficient, but when the food in question is consumed within a few hours before high intensity exercise, the result can be anaphylaxis.<unk>  are specifically mentioned as a causative food. One theory is that exercise is stimulating the release of mediators such as histamine from IgE-activated mast cells. Two of the reviews postulate that exercise is not essential for the development of symptoms, but rather that it is one of several augmentation factors, citing evidence that the culprit food in combination with alcohol or aspirin will result in a respiratory anaphylactic reaction.
