Synthetic Vaccine May Help Eliminate Polio
Reprinted from the Voice of America
 
The development of the oral polio vaccine more than 50 years ago is credited with virtually eradicating the illness worldwide. Now, researchers are looking ahead to the day when the disease no longer exists, even outside the laboratory.
To hasten that day, researchers in Britain are developing a synthetic polio vaccine. It works like one made from live, weakened virus, except it contains synthetic particles inside a viral shell.  
The man-made vaccine mimics the structure of the polio virus, so it would be able to raise a strong immune response in humans. And because it does not contain the pathogen, there would be no risk of exposure, even in the case of an accidental release during the manufacture process.
