[ Editor's Note: Chryste Gaines, MBA, Olympic gold and bronze medal sprinter and former teammate of Marion Jones in the 2000 Sydney Olympic Games, stated the following in a Dec. 22, 2008 email to in response to the IOC ruling:
"We are being unfairly punished. If the drug testing agencies cannot determine if an athlete is taking performance enhancing drugs how are the teammates supposed to know?... It negates all the family functions, church functions, and social events we missed in the name of winning an Olympic medal." ]
“We took samples of their fish from the farm where it was suspected that the fish grew faster …and want to find out the genetic makeup of the fish and also to find out other reasons why their fish could be growing faster than the others. It could be the feed that is given to them, other factors like some medication, chemicals mixed for the fish or something. So we took samples of the fish and took them to the Water Research Institute and at the moment, the institute is trying to do some findings and some research to ascertain the genetic makeup of the fish they are growing,” she stated.
Recombinant vaccines, such as those used against HBV and HPV, are made using a gene from the (disease-causing) pathogen. The gene is inserted into a cell system capable of producing large amounts of the protein of interest. The protein produced is capable of generating a protective immune response. For example, the gene for the hepatitis B surface antigen (HBsAg) is inserted into yeast cells, which replicate and produce large amounts of HBsAg. This is purified and used to make vaccine. The advantage of this approach is that it results in a very pure vaccine that is efficient to produce.
