Question

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

Answer 1

A benefit of genetic engineering is the production of valuable proteins that have helped in managing of illness in human beings. Bacteria were genetically engineered to produce proteins of medical importance. One example of such a protein is human insulin which is given the name humulin and is made using E. coli bacteria.Earlier, insulin from pig cells was used to treat patients with diabetes but many of them could not tolerate it because it has a slightly different arrangement of amino acids from that of humans and so the human body rejects it. Humulin is tolerated by the human body and so many patients are now using it to lead normal lives.

Answer 2

The main purpose is to prevent the spread of the diseases without using the syringes.

Step-by-step explanation:

The edible vaccine is considered to be the bio-friendly and is a storable vaccine that are necessary for the cure of very harmful diseases like Diarrhea, smallpox, hepatitis. The edible vaccine is easy to administer and are cost effective.

One of the major challenges posed by the developing nation with respect to the administration of a vaccine is their storage and handling that reduces the sterility of the needles. That is known to increase the risk of widespread diseases.

So, in order to prevent such risk edible vaccine is developed by genetic engineering technique.
