The geosphere includes the rocks and minerals on Earth â from the molten rock and heavy metals in the deep interior of the planet to the sand on beaches and peaks of mountains. The geosphere also includes the abiotic (non-living) parts of soils, and the skeletons of animals that may become fossilized over geologic time.
Four types of vaccines are currently available: 1  Live virus vaccines use the weakened (attenuated) form of the virus. 2  Killed (inactivated) vaccines are made from a protein or other small pieces taken from a virus or bacteria.  Toxoid vaccines contain a toxin or chemical made by the bacteria or virus.
Classification of vaccinesâ. There are two basic types of vaccines: live attenuated and inactivated. The characteristics of live and inactivated vaccines are different, and these characteristics determine how the vaccine is used.Live attenuated vaccines are produced by modifying a disease-producing (âwildâ) virus or bacteria in a laboratory.n order to produce an immune response, live attenuated vaccines must replicate (grow) in the vaccinated person. A relatively small dose of virus or bacteria is given, which replicates in the body and creates enough virus/bacteria to stimulate an immune response.
