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.
Analysis of virus-specific CD4 + and CD8 + T cell responses and their contribution to vaccine-mediated immunity is more complex than the analysis of antiviral antibody responses.accines play a vital role in protecting the host against infectious disease. The most effective licensed vaccines elicit long-term antigen-specific antibody responses by plasma cells in addition to the development of persisting T cell and B cell memory.
