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.
DNA vaccines are able to stimulate cell-mediated immunity whereas traditional vaccines stimulate humoral immunity. Traditional vaccines have been developed against numerous bacterial and viral pathogens, but the development of vaccines against many important viruses has been elusive.Generally where immunization has been successful, the host immune system makes neutralizing antibodies against the pathogen.raditional vaccines have been developed against numerous bacterial and viral pathogens, but the development of vaccines against many important viruses has been elusive.
