Vaccination Vaccination is a term derived from the Latin vacca (cow, after the cowpox material used by British physician Edward Jenner (1749-1823) in the first vaccination in 1796). A vaccine stimulates the antibody production and formation of memory cells without causing of the disease. Vaccines are made from killed pathogens or weakened strains that cause antibody production but not the disease. Recombinant DNA techniques can now be used to develop even safer vaccines. The immune system can develop long-term immunity to some diseases. Man can use this to develop vaccines, which produce induced immunity. Active immunity develops after an illness or vaccine. Vaccines are weakened (or killed) viruses or bacteria that

Passive immunity is the type of immunity when the individual is given antibodies to combat a specific disease. Passive immunity is short-lived. Emergent Viruses Viruses are usually quite specific as to their hosts and even to the types of cells they infect in a multicellular host. Recently, some viruses appear to have shifted their host: HIV, hantavirus, and ebola appear to be either viruses shifting to a new (human) host or else viruses whose existence and effects are just now being realized by scientists and the general public....
