Yes i agree with the concept. Because when harmless antigen is administered into human body, antibody produces against that particular antigenic structure. In the process, memory plasma cells are formed. Now, when the similar structure other antigen attacks, our immunity quickly derives those memory plasma cells to fight with it very quickly, thus reducing the time of response & energy too.
