The plant-based vaccine production method works by isolating a specific antigen protein, one that triggers a human immune response from the targeted virus. A gene from the protein is transferred to bacteria, which are then used to “infect” plant cells. The plants then start producing the exact protein that will be used for vaccinations. [6]
Farmers have manipulated plants and animals through selective breeding for decades of thousands of years in order to create desired traits. In the 20th century, a surge in technology resulted in an increase in agricultural biotechnology through the selection of traits like the increased yield, pest resistance, drought resistance, and herbicide resistance.
Vaccine against HIV virus; Anthrax vaccine (from tobacco) Antibodies against Ebola virus [9] By being able to genetically alter plants to create specific antibodies, it is easier to produce antibodies that will fight diseases not only for plants but for human as well. For that reason, plantibody applications will move more towards the medicinal ...
Iowa State University – immunogenic protein from E. coli bacteria in pollen-free corn as a potential vaccine against E. coli for animals and humans [55] [56] [57] Kentucky Bioprocessing took over Large Scale Biology's facilities in Owensboro, Kentucky, and offers contract biomanufacturing services in tobacco plants, grown in greenhouses or in ...
Genetically modified plants have been engineered for scientific research, to create new colours in plants, deliver vaccines, and to create enhanced crops. Plant genomes can be engineered by physical methods or by use of Agrobacterium for the delivery of sequences hosted in T-DNA binary vectors .
Edible vaccines are considered a "pharmafood" which is a food source that increases health while also fighting diseases. [1] The benefit of using plants is that plants are efficient vectors for vaccine production. [1] Many traditional vaccines that are developed from cultured mammalian cells can lead to contamination with animal viruses.
A genetic vaccine (also gene-based vaccine) is a vaccine that contains nucleic acids such as DNA or RNA that lead to protein biosynthesis of antigens within a cell. Genetic vaccines thus include DNA vaccines , RNA vaccines and viral vector vaccines .
The process of serial passage yields a live vaccine. There are both advantages and disadvantages to this. Most notably, live vaccines are sometimes more effective and more long-lasting than inactivated or other types of vaccines. [10] [11] However, just as the virus evolved to become attenuated, it may reverse-evolve in the host, leading to ...
