ABSTRACT
Vaccines exhibit great potential to fight against infectious disease. Edible vaccines make contact with the lining of digestive tract by which it activates the mucosal as well as systemic immunity. These properties of edible vaccines provide more effective protection from the dangerous microorganisms which cause deadly diseases. However, among properties of edible vaccines, there are many other issues, which are still to be addressed. For example, the vaccine production from the plants is in low amount. While solving such problems, the researchers also have to make sure that the vaccine produced by the fruits should have a predictable dose.
