Is Allergy Contagious?

As an old allergic, such remarks make me laugh each time I hear them: "is allergy contagious?" or "is there a vaccine to prevent catching an allergy?" or "which is the incubation period for allergy?".

I can understand people who are in good health are not interested in such morbid details, but once they learn they've got a disease, they should try to educate themselves, to get some information about the lifestyle of other people who got the same ailment.

Allergy is one of the most neglected, thus most dangerous diseases which have no cure and not vaccine yet.

To answer now the first question, no, allergy is not contagious, but it is believed to be genetically inherited, so if you have antecedents in your family you should get yourself tested for the most common allergens, because you are at high risk.
