Immune system
a complex system in the body made of a group of cells that all work together to defend and protect the body from enemies or invaders, fighting against potentially harmful substances like viruses, bacteria and other germs, in order to protect the body health.

  • active immunity - immunity acquired by the antibodies produced by the personís own immune system. This type of immunity can be brought about by a natural infection or by a vaccine. It is usually long lasting
  • passive immunity - immunity acquired by transfer of antibodies produced by other person's immune system, either naturally (from pregnant woman to her unborn child) or artificially (as by injection). It is effective but usually last few weeks to months
Immunity is indicated by the presence of specific antibodies in the blood and can be determined with a laboratory test.
the process of inducing immunity to a specific infection or disease, typically delivered through a vaccination.
immunologic test allowing the visualisation of a specific antigens that react with the antibody.
a general term for blood proteins capable of acting as antibodies which bind to invading organisms, leading to their destruction. There are five classes of immunoglobulins : IgA, IgD, IgE, IgG, IgM.
