Actually, you have been exposed to those other antigens even if you haven't had a blood transfusion go wrong. Let me explain.
The ABO blood type system is based on what kinds of sugars are expressed on the surface of a person's red blood cells (RBCs). Type A people are not born with anti-B antibodies, but they do make them by the time they are 1yo. The reason for this is that those molecules that account for the ABO system aren't that unique. They are basically a carbohydrate chain made of 4-5 simple sugars which is bound to protein on the RBC surface. So you do get exposed to other antigens of the ABO system, but it's not through blood transfusion. Typically you will be exposed to similar sugar molecules from food, bacteria, and viruses.
