What is the purpose of using genetic engineering to create edible vaccines?

The purpose of using genetic engineering to create edible vaccines is to develop a more convenient and cost-effective method of immunization. By incorporating vaccine genes into food plants, these edible vaccines can stimulate an immune response when consumed, potentially reducing the need for needles and cold storage. This approach can improve accessibility, especially in developing regions, and enhance public health by providing an easier way to deliver vaccines against various diseases.
