According to reports, the scientists used seeds of a plant called thale cress also sometimes called mouse-ear cress, to produce antibodies against the hepatitis A virus.
The local news Web site Flandersnews.be said this new development could help scientists produce more drugs that are effective in fighting cancer and infections.
Earlier Dutch scientists succeeded in producing antibodies in tobacco plants.
Antibodies are proteins that can activate immune systems in the human body. They are effective against infections and cancers.
The report said the new antibodies would take another 10 years to be commercially available. The scientists say producing antibodies using plants is cheaper than using animals.
