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!
This is one of the good things GE could do but it could also be
very dangerous if not carefully monitored. The
production of pharmaceuticals like vaccines by making genetically
engineered plants or animals is called Pharming.
