Riems has been inhabited since prehistoric times as
Stone Age and
Slavic archaeological finds demonstrate. The island later belonged, together with the adjacent village of
Gristow, to the family of Dotenberg. Between 1375 and 1382, Riems and Gristow became the possession of the city of Greifswald, which leased the then uninhabited island out as
pasture land. After 1820, the city built a homestead but sold it back to its previous tenant in 1883. Riems is home to the oldest
virological research institution in the world, now called the
Friedrich Loeffler Institute, which was built by
Friedrich Loeffler in 1910. Loeffler, a professor at the
University of Greifswald, ran filtration tests in 1898 and found that the cause of
foot-and-mouth disease was not a
bacterium, but a previously unknown class he called "the smallest of all organisms". He had determined it to be a virus. After investigations showed that Loeffler had inadvertently infected the whole region of Greifswald with foot-and-mouth disease he moved to the safer location of his institute on the island of Riems in 1910. The
Third Reich used the institute in Riems to research bioweapons. While
East Germany controlled Riems approximately 800 people were working on vaccine research and development, today there are less than half that number. The population on the island is quite small. There are only 13 houses, five one- or two-family homes and eight apartment buildings, with a total of 62 residential units. Since 1997, the research complex is the headquarters of the Riemser Friedrich-Loeffler-Institute (FLI). The duties of the FLI include research on animal diseases, such as
Bovine spongiform encephalopathy, foot-and-mouth disease and
swine fever, and the development of preventive and protective measures against it, especially veterinary vaccines. As of 2006, Riems was working on a vaccine for the
avian flu. By 2010, the Institute was to reduce their current locations Tübingen, Wusterhausen and Jena to just Jena and Riems. The total budget for the expansion work is some 150 million €. The construction needed to be handled carefully because of the historically rich old buildings. The former production plant for animal vaccines was successfully privatized as Riemser Arzneimittel AG. It has about 150 employees. After the 1990s the populated area in the western part of the island was freely accessible for some years. However, because of the renewed research work with viruses the island is again
closed to the public. Quarantine stables and laboratories security levels are
level 4. This means employees and visitors to the complex must change their clothes, and shower, when entering and exiting. ==See also==
