Immunisation

active immunity:

• inject with a antigen that will promote the primary immune response, but has been modified so that it doesnt cause a virus. the immune system makes memory cells, so the secondary immune response.

passive immunity:

• injecting antibodies against certain pathogens into the blood.
• used when someone has already been infected.
• occurs naturally when a mother passes antibodies to her child.

monoclonal antibodies:

• antibodies of one particular shape made by a clone of a single B-cell.
• if monoclonal antibodies are mixed with a sample containing a mixture of protiens, the antibodies will bind specifically and tightly to only one protien in the sample.
