"Medicines and vaccines often are costly to produce and sometimes require special storage conditions not readily available in third world countries. Researchers are working to develop edible vaccines in tomatoes and potatoes16, 17. These vaccines will be much easier to ship, store and administer than traditional injectable vaccines."

would the benefits of this outweigh the risk of allergies/pesticides and all the other dangers of GMOs? what if someone was allergic to a certain vaccine?
