What type of immunity is slow and takes time to give its full effective response?

Step-by-step solution

The primary and secondary immune responses are carried out with the help of two special types of lymphocytes present in our blood, i.e., B-lymphocytes and T-lymphocytes.B-lymphocytes produce an army of proteins in response to pathogens in our blood to fight them. These proteins are called antibodies. Active immunity is slow and takes time to give its full effective response when a host is exposed to antigens. Before transplantation, tissue matching and blood group matching are essential to prevent rejection of the
