In brief: Immune response

The DTaP (big D) signifies a full dose of diphtheria antigen along with the other components,which is given to the child's emerging immune system to stimulate the immune system. The TdaP (little d) represents a vaccine with less diphtheria antigen, because a kids dose would bring on more side effects but not more protection.
