In brief: Hygiene hypothesis

The immune system has two opposing arms, one makes protective antibodies against bacteria and viruses, the other makes allergic antibody.
One theory is that early antibiotic use disrupts the gut flora which tips the scale away from fighting infection and more toward making allergic antibodies. Clean environments might be at fault as well, farm kids don't get allergies as much as city kids.
