Vaccines protect you from nasty diseases like polio by priming your body's immune system to fight off invading disease organisms. Most of these have to be injected into you with a needle and syringe and it hurts a bit. I guess you, like most kids, don't like having vaccinations much. So imagine if you could get your vaccination by eating a potato or a banana [1]! This is one of the possibly good things GE could do. Unfortunately, one 'good' baby has already been thrown out with the bathwater. A small company was experimenting with GE potatoes 
which made a vaccine against hepatitis B, a nasty virus which triggers liver cancer and kills one million people each year. This company, called Axis, was also developing vaccines against cholera and two other diarrhoeal diseases - big killers of kids in poor countries. All its plants were grown inside glasshouses, not in the open air. Axis worked with plants rather than with the bacteria used by most medical biotechnology firms. But all the row about GE which has erupted around the world, "put us in the firing line with investors who are worried we might get tarred with the GM food brush", said one of the company's staff. Axis has now gone bust. [2]
