The term “immunity” is referred to the . resistance of an individual . towards . injury. caused by . microbial stimuli . (microorganisms & their products) & . Principles . of Vaccination. : . Vaccination is one of the most effective medical interventions to reduce morbidity and mortality of infectious diseases. The main principle of vaccination is the proactive induction of a protective immune response by mimicking the natural interaction of an infectious pathogen (bacteria, viruses, etc.) with the human immune system (Fig 1). Immunostimulatory. and . fusogenic. liposomes (IFLs). . IFL may attract innate cells like DCs, macrophages leading to their . immunostimulation. and release of . proinflammatory. cytokines (pathway a). IFL may get . Features of adaptive immunity:. Adaptive immunity is characterized by the following:. 1. Antigenic specificity: (. highly specific).. 2. Diversity : . ( each antigen there is specific T-cell and B-cell for it)..
