Genetically modified crops can be implied in order to solve global issues, including the treatment of the Hepatitis B virus.
Plant-based vaccines are able to do so, since plants are approved to be effective sources of vaccines. Many kinds of crops have been genetically engineered to produce vaccines in them. Bananas are suitable as nutritional vaccines because they grow widely in many parts of the developing world, can be eaten raw and are liked by most children. One way of making plant-based vaccines depends on the bacterium Agrobacterium tumefaciensto to transfer and send the genetic blueprints for viral or bacterial “Antigens”,(proteins that elicit a targeted immune response in the recipient) in plant cells. Experiments prove that the vaccine worked properly,and it has a low cost as well.It is created when an altered form of a virus gets injected into a moderately ripe piece of banana, the virus’ genetic material quickly becomes a permanent part of the plant’s cells. As the plant grows, its cells produce the virus proteins, (but not the infectious part of the virus).
When eaten it passes into the intestine and then into the bloodstream producing antibodies against hepatitis B , working the same way as a traditionally injected, but much more expensive vaccine. However, just like any other thing, these edible vaccines have both positive and negative implications, that will be taken into account from an economical point of view.Some cons of producing banana vaccines are using intellectual property, as corporations are controlling the means of productions, and are forbidding farmers to save seeds by using several laws expressed in contracts with these farmers. Moreover, these companies are highly expected to sell GMO seeds as a valuable good, without returning it to the main seller once fully used. This might greatly affect the distribution of GMO seeds and the way in which they are distributed over farmers, since the farmers will be greatly affected when their seeds are stolen and their hard work is taken off by someone else.
Money would not be equally distributed over the people who deserve it as well. Other than that, researchers and developers are doubting that there will be customers that desire to buy bananas that cannot be sold on a consumer’s market. The banana-based vaccines need”intensive quality control regulations”, since it is still unclear who will be responsible of distributing the seeds in order to pay for the expensive regulations of growing them.
On the other hand, banana vaccines have one explicit purpose, which is strengthening the immune system to rapidly and quickly destroy speci?c disease-causing agents, before they can multiply enough to cause symptoms. It has many positive implications including that the plants could be grown with a cheap and low price,locally,following the standard growing methods of a given region. Since many food plants can be reproduced effortlessly, the crops could be initially produced during an unspecified period of time, without the growers having to purchase more seeds or plants continuously. Plant-based vaccines would also avoid the logistical and economic problems such as having to transport traditional preparations over long distances, keeping them cold on route and at their destination.
And, being edible, the vaccines would require no syringes (costs a large amount of money).These factors make the vaccines more practical as a good that can be consumed and that is economically beneficial as well.
