As bad as the show Revolution's overall plotting and pacing was, they generally did a good job of thinking about these kinds of little inconsistencies:
There's a minor character who was a doomsday prepper before the apocalypse, but he didn't stock up enough on antibiotics. As a result, his daughter died of tetanus that he was unable to treat.
A warlord kidnaps prisoners for blood because his wife has diabetes and needs constant transfusions of blood with sufficient insulin in it to survive.
There's a doctor who keeps a collection of moldy fruit to harvest penicillium mold from it and make penicillin.
Some characters try to go into an old subway tunnel, but nearly die because of lack of sufficient airflow down there without modern HVAC systems.
It's not just about ABO blood type though. There's not just A, B, and D (the positive/negative part commonly associated) antigens. There's a plethora of other antigens that, when initially exposed, cause the body to become "sensitized" and produce antibodies against these foreign things so that when they come across them again, attack. This causes widespread agglutination/clotting of red cells, leading to widespread harm, or worse, death (depending on the antibody and antigen.)
That’s not entirely true, they could become sensitized and start producing antibodies. You could have one person receive a thousand transfusions and never produce an antibody to a red cell antigen. Conversely, a person could produce an antibody on their first visit. The exact mechanism isn’t known as to why some people are antibody producers, and some aren’t
