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.
Thus humoral immunity involves the production of antibodies by plasma cells and this constitutes the primary immune response. When there is an exposure to the same antigen second time, the memory B cells are alerted and rapidly differentiate into plasma cells that produces antibodies.This constitutes the secondary immune response.hen there is an exposure to the same antigen second time, the memory B cells are alerted and rapidly differentiate into plasma cells that produces antibodies.
