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.
Vaccination (immunization) is a way to trigger the immune response. Small doses of an antigen, such as dead or weakened live viruses, are given to activate immune system memory (activated B cells and sensitized T cells).ome of these directly attack foreign substances in the body, and others work together to help the immune system cells. Lymphocytes are white blood cells, which includes B cells and T cells. 1  B cells produce antibodies.
