In October 2007, during a plenary meeting of the working group CEN/TC 216, it was suggested that the Sabin poliovirus type 1 vaccine LSc-2ab should be replaced by the poliovirus type 1 vaccine strain CHAT.
In contrast to other European countries, in particular the Netherlands, Denmark, and the UK, IPV was not successfully implemented in Germany at this time and reached only 5 percent of its population in 1960.
In Germany, vaccination against poliomyelitis was introduced in 1962 using the oral polio vaccine (OPV) containing Sabin strain LSc-2ab.
The vaccination schedule was changed from OPV to an inactivated polio vaccine (IPV) containing wild polio virus type 1 strain Mahoney in 1998.
In Germany, the virus can be obtained from the German Association for the Control of Viral Diseases [Deutsche Vereinigung zur Bekämpfung der Viruskrankheiten (DVV)].
Another source is the National Institute for Biological Standards and Control (NIBSC), offering the WHO reference strain Sabin Original Virus, second passage (SO 2) (NIBSC, code 01/528).
