the immune response

  • pathogens have a unique antigen on their surface that corresponds to the antibody of the lymphocytes

  • the antigen binds to its corresponding antibody on the lymphocyte, activating the lymphocyte

  • the lymphocyte then divides over and over again to produce clones

  • other lymphocytes remain in the blood as memory lymphocytes, ready to respond immediately if the same pathogen returns

how do vaccines work?

  • person is injected with a weakened or dead version of the microbe

  • white blood cells produce antibodies to fight off the microbe

  • the microbe will be destroyed quickly so the person doesn’t become unwell

  • if they get infected in the future, the body will recognise the microbe and antibodies are produced quicker
