Transgenic Plant Vaccines

Transgenic plant vaccines are genetically modified plant vaccines in which a selected gene is encoded for the desired and modified antigen which, when taken orally, causes a strong immune response in the body. Vaccines produced from plant cells are inherently safe as they pose no risk of microbiological contamination associated with vaccines of animal origin and eliminate the risk of pathogenicity, return to virulence and excretion. Oral administration stimulates mucosal immunity (the first line of defense) in the tissues lining the respiratory system and eliminates the risks associated with the injection. The structure of plants can help maintain antigenic property even after degradation in the intestine. The abundance of plant availability makes vaccine production low cost apart from the low cost of storage and transport. They act by different mechanisms of action mainly stimulating the lymphoid structure of the intestine. This review highlights the development of the transgenic plant vaccine, its action and certain important diseases of animals, poultry and humans and the state of the plant vaccine developed against them.
