What is the purpose of using genetic engineering to create edible vaccines? a. to create vaccines that are capable of lasting years in the body to prevent future infectionsb. to diminish negative side effects that may occur from administering vaccines with syringesc. to enhance the flavor of vaccines so peopleare more likely to use themd. to prevent widespread diseases in developing countries without using syringes

Option D

Explanation: Edible vaccines can be defined as the vaccines which is the edible part of plant which are genetically modified to make specific components (antigen) of a specific pathogen to generate immunity against a disease.

The main objective of the Genetic engineering to create edible vaccine is to prevent the widespread diseases in the developing countries without using intravenous mode of administration (syringe).

The conventional mode of vaccination through syringe is more costly due to its production, transportation and storage. Developing countries represent poor and flung parts of the world and people living there have  higher chances of being infected by diseases.

So, plants (edible vaccines) was found effective to solve this problem.
