Vaccines are developed using different processes. They may contain live viruses that have been attenuated (altered or weakened so as to not cause disease when administered); inactivated or killed organisms or viruses; inactivated products such as toxoids; microbial products; or genetic material (segments of the pathogen). It is interesting to note that due to viruses being less complex, active immunisation is extremel effective against viruses compared with bacteria, fungi and protozoan diseases....
