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.
These effectors are controlled by regulatory T cells (Treg) that. are involved in maintaining immune tolerance.2 Most antigens. and vaccines trigger both B and T cell responses, such that there. is no rationale in opposing antibody production (âhumoral. immunityâ) and T cell responses (âcellular immunityâ).
