You should include a minimum of 3 scholarly references. Include a title page, in-text citations, and a reference page in APA format.
Immunity is the state of protection against infectious disease conferred either through an immune response generated by immunization or previous infection or by other non-immunological factors. This article reviews active and passive immunity and the differences between them: it also describes the four different commercially available vaccine types (live attenuated, killed/inactivated, subunit and toxoid): it also looks at how these different vaccines generate an adaptive immune response.
Immunity can be described as either active or passive, depending on how it is acquired:
Active immunity involves the production of antibodies by the body itself and the subsequent development of memory cells
Passive immunity results from the acquisition of antibodies from another source and hence memory cells are not developed
Active immunity will result in long-term immunity but passive immunity will not (due to the presence or absence of memory cells)
Both active and passive immunity can be induced by either natural or artificial mechanisms
Examples of Active Immunity
Natural – Producing antibodies in response to exposure to a pathogenic infection (i.e. challenge and response)
Artificial – Producing antibodies in response to the controlled exposure to an attenuated pathogen (i.e. vaccination)
Examples of Passive Immunity
Natural – Receiving antibodies from another organism (e.g. to the foetus via the colostrum or a newborn via breast milk)
Artificial – Receiving manufactured antibodies via external delivery (e.g blood transfusions of monoclonal antibodies)
