Causes
Scientists think both genes and the environment have something to do with it. Normally, your immune system fights germs. It is your body's defense system. In most allergic reactions, however, it is responding to a false alarm.
Some studies have shown a link between vaccinations and food allergies.[2][3]
Symptoms
Allergies can cause a runny nose, sneezing, itching, rashes, swelling or asthma. Symptoms vary. Although allergies can make one feel bad, they are usually not fatal. However, a severe reaction called anaphylaxis is life-threatening.
