Question
What is meant by edible vaccines?
Solution
- Currently, biotechnology is being used to produce edible vaccines, by growing genetically modified plants that can produce transgenic vegetables like potatoes.
- The desired gene is isolated from the human pathogen. e.g. Vibrio cholerae, Escherichia coli, etc.
- This gene is then transferred to the plant cells through a transgenic plant virus that infects the pieces of plant leaves.
- By tissue culture techniques, the entire plant is developed from these leaf pieces which contain the desired gene.
- The potatoes produced by these plants when consumed raw will help the individual develop immunity against the pathogen and are thus referred to as edible vaccines.

Read the following paragraph and write the answers to the questions based on them.
Vaccination gives either permanent or temporary immunity against a specific pathogen or disease. Traditionally, vaccines were prepared with the help of pathogens. Completely or partially killed pathogens were used as vaccines. However, due to this, there were chances of contracting the disease in case of some persons. Hence, as an alternative, scientists tried to artificially produce vaccines with the help of biotechnology. For this purpose, scientists produced the antigen in the laboratory with the help of genes isolated from the pathogen and used it as a vaccine. Thus, safer vaccines are being produced. Work on production of edible vaccines is in progress and presently, potatoes are being produced with the help of biotechnology. These potatoes are called transgenic potatoes. These potatoes will act against bacteria like Vibrio cholerae, Escherichia coli. Consumption of these raw potatoes generates immunity against pathogens. For the production of such edible vaccines, antigens are produced by isolating the desired gene from human pathogens and injecting it into plants.
