Principle Behind Vaccination and Immunization
The principle of immunization or vaccination is based on the immune system’s property of ‘memory’. The vaccines given to individuals generate memory B cells and T cells that identify the previously attacked pathogen and kill them by producing antibodies against them. For example, in the case of snakebites, the doctors give an injection that consists of preformed antibodies against the venom. Similarly, if our body is diagnosed with tetanus, doctors give us an injection that consists of the weak pathogen of tetanus bacteria.
