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.
The principle of immunisation or vaccination is based on the property of âmemoryâ of the immune systems. Vaccines also generate memory-B and T cells that recognise the pathogen quickly. In snake bites the injection which is given to the patients contains preÂ­formed antibodies against the snake venom. This type of immunisation is called passive immunisation. The process of introduction of vaccine into an individual to provide protection against a disease is called vaccination.
