ANATOMY

Detailed explanation-1: -The plasma cells produce antibodies (Y-or T-shaped molecules), which are trained specifically to attach to and inactivate the organism you are being vaccinated against. This response from your immune system, generated by the B lymphocytes, is known as the primary response.

Detailed explanation-2: -Immunization protects future generations. Vaccines have reduced and, in some cases, eliminated many diseases that killed or severely disabled people just a few generations ago. For example, smallpox vaccination eradicated that disease worldwide.

Detailed explanation-3: -If the body is exposed to the same pathogen more than once, the antibody response is much faster and more effective than the first time around because the memory cells are at the ready to pump out antibodies against that antigen.

Detailed explanation-4: -Vaccines teach your immune system how to create antibodies that protect you from diseases. It’s much safer for your immune system to learn this through vaccination than by catching the diseases and treating them. Once your immune system knows how to fight a disease, it can often protect you for many years.
