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.
How does a vaccination help the immune system? A vaccine contains weakened or dead pathogens that the vaccine is against. For example the polio vaccine would contain the dead/weakened polio virus. This means that the Whiteâ¦ blood cells will identify the virus and produce the antibodies to destroy the virus. On the antibodies is a protein that basically can remember the shape of the virus.
