Detailed explanation-1: -Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. Newer vaccines contain the blueprint for producing antigens rather than the antigen itself.
Detailed explanation-2: -Invasive bacteria such as Salmonella, Listeria, Yersinia, Shigella and Mycobacterium bovis BCG have been used as vaccine vectors, capable of mounting potent humoral and cellular immune responses.
Detailed explanation-3: -Vaccines contain dead or weakened microbes of a particular disease.
