Can someone fill me in on allergies and allergy shots?

June 1st, 2011
About allergies themselves: How does one develop a new allergy? How does one develop more severe allergies to things they were already allergic to? I’ve heard some theories about incremental exposures over time triggering new or worsening allergies. Is that the case?
About allergy shots: It’s my understanding that the allergy serum used in the shots contains small amounts of the allergen(s), increasing the amount over time, in the hopes of developing an ‘immunity’ to the allergen(s) or at least mitigating the severity of the allergic response.
These two ideas seem incompatible to me. What am I missing?
Side question: How does one’s body decide what it will be allergic to?
