Abstract

Vaccines, as a form of targeted immunization, are a triumph of medicine because without them millions of people would have died each year. There is active and passive immunization. Production of antibodies as a result of exposure to antigen is called active immunization, while passive can be gained with direct input of antibodies which were actively made in another person or animal. Viral vaccines represent a form of artificial active immunization which results with long-term immune memory. There are several types of vaccines: vaccines that contain live, attenuated pathogens whose ability to cause disease was attenuated with certain procedures, but they’ve kept the ability to replicate themselves in cells and to induce immune response in vaccinated individual; vaccines that contain inactivated viruses or their components which cannot replicate or cause disease, but can induce immune response. Besides them, there are subunit protein vaccines, live recombinant vaccines, synthetic peptide vaccines and DNA vaccines. By now, the only virus that has been eradicated with vaccination program is smallpox virus, while polio virus is in process of eradication but still causes troubles. Simultaneously with vaccination, anti-vaccine movements occur. The problem which these movements cause is encouraging not to get vaccinated and because of that there are repeating cases of heavy illnesses which have been under control for years.
