Recent Progress and Challenges in the Development of Edible Vaccines Produced by Genetically Modified Plants

Biotechnologists have pioneered the idea of an edible vaccination in recent years. Subunit vaccines, such as those used to create edible vaccines, involve the introduction of certain genes into transgenic plants, which are subsequently coaxed into producing the corresponding protein. Bananas, potatoes, legumes, lettuce, soybeans, corn, and rice are all examples of foods that fall under this category. They have a low unit cost, can be stored conveniently, and are simple to administer to patients of varying ages. There is great hope that the use of edible vaccinations, particularly in underdeveloped countries, could drastically reduce the prevalence of diseases, including measles, cholera, hepatitis B, and diarrhea. The development of effective and widely applicable edible vaccination, however, faces a number of technological and regulatory hurdles. When compared to traditional immunizations, edible vaccines offer significant cost savings, increased productivity, and reduced risk. It raises the possibility of a more efficient approach to illness prevention. This article includes important uses, production, host plants, benefits, drawbacks, mechanism of action, and many regulatory difficulties related to edible vaccines. In this article, we have discussed the most recent developments and successes with edible and intradermal vaccines in terms of the system used for immunogen production, the molecular properties of these vaccines, and their ability to generate a protective systemic and mucosal response.
