The immune response to a pure polysaccharide vaccine is typically T-cell independent, which means that these vaccines are able to stimulate B cells without the assistance of T-helper cells.nother way to produce active immunity is by vaccination. Vaccines interact with the immune system and often. produce an immune response similar to that produced by. the natural infection, but they do not subject the recipient to. the disease and its potential complications.
The purpose of all vaccines is to trigger an immune response without causing a disease. Vertebrate immune systems have the ability to produce specific immune responses to specific antigens.Antigens are structures on the surface of a pathogen that the immune system can recognize.Once the immune system has been exposed to a pathogen and created an immune response to the pathogen, it can be said to have developed immunity to that pathogen.For the rest of the life of the organism the immune system can quickly produce antibodies in response to the antigens of the pathogen.ntigens are structures on the surface of a pathogen that the immune system can recognize.
