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.
Flu vaccines are routinely available for seasonal influenza, but these vaccines are not likely to be protective against flu caused by the H1N1 (formerly termed swine flu) virus. There is a separate vaccine against the H1N1 flu.There are two types of seasonal flu vaccines, the injection (with killed virus) and nasal spray vaccines (containing live but weakened virus). The vaccine is generally effective against the influenza virus within two weeks of administration.he vaccine is termed an attenuated vaccine because the viruses are weakened so that they do not cause severe flu symptoms. The nasal spray flu vaccine (LAIV) has been approved by the FDA for use in nonpregnant healthy people between two and 49 years of age.
