An individual is said to be immune to a particular pathogen when it may be introduced into the body, without causing illness. In contrast to innate immunity, the immune system is changed as a result of exposure to a particular antigen. Acquired immunity is specific to a particular antigen. For example, previous exposure to the measles virus will have allowed the immune system to adapt, generating immunity to any future measles infection. However, because the response is specific, the individual may still suffer from mumps, influenza, or indeed any other antigenic organism it has not previously been exposed to. Antigens (antibody generators) An antigen is anything the immune system recognises as being foreign. When detected, antigens generate an immune response in the body. It is antigens which stimulate the production of antibodies, which are the immune proteins. Usually an antigen is a foreign protein that the body recognises as non-self. The outer coatings of bacteria and viruses contain such foreign proteins. Non-protein large molecules (with a molecular mass of over 1000) will also be antigenic if introduced into the body. So a wide variety of living and non living things can act as antigens; such things are said to possess antigenicity…","meta_description":"Official UK government report on the debate https://hansard.parliament.uk/commons/2022-10-24/debates/FF880636-BC3B-4BDB-A5E0-D6D4B82B2888/Covid-19Vaccines…","key_points":[],"chapters":[],"topics":[],"duration_seconds":1273,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/dr-john-campbell-7851784/episodes/uk-parliament-vaccine-discussion/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/dr-john-campbell-7851784/uk-parliament-vaccine-discussion.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
