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]
Antibodies produced in plants have many advantages that are beneficial to humans, plants, and the economy as well. They can be purified cheaply and in large numbers. The many seeds of plants allow for ample storage, and they have no risk of transmitting diseases to humans because the antibodies are produced without the need of the antigen or ...
On the other hand, plants are still sufficiently closely related to animals and humans that they are able to correctly process and configure both animal and human proteins. Their seeds and fruits also provide sterile packaging containers for the valuable therapeutics and guarantee a certain storage life.
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.
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 ...
Here’s why Dr. Leana Wen recommends people get the new RSV vaccines available for older people, pregnant people and infants. ... this is a very good level of protection, and people at risk for ...
As a result, genetic vaccines and live vaccines generate cytotoxic T-cells in addition to antibodies in the vaccinated individual. In contrast to live vaccines, only parts of the pathogen are used, which means that a reversion to an infectious pathogen cannot occur as it happened during the polio vaccinations with the Sabin vaccine.

World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
