Mexico develops oral vaccines with tomatoes and bananas
A few days ago, Mexican researchers developed new oral vaccines by cultivating genetically modified plants. These vaccines are expected to be used to prevent stomach diseases, hepatitis B, cholera and malaria in the future, and may also have a certain effect on the prevention of cancer. Researchers have put the disease-causing genes of different diseases into plant embryos of tomatoes or bananas, and allowed the embryos to grow to 5 cm in vitro, and then transplanted them into fertile soil and cultivated in the traditional way. Mature fruits contain antigenic proteins. This active ingredient can be extracted to make oral vaccines against different diseases. After the antigen protein in the new vaccine enters the human body, it can mimic the process of the virus invading the human body, activate the immune system, and make the body produce antibodies to related diseases, thereby gaining immunity. Compared with traditional vaccines, the superiority of this new vaccine is that it does not require refrigeration and injection, thus reducing drug prices by about 50%. At the same time, this kind of vaccine produced by plants is less toxic and will not harm the human body. At present, the research center has begun to cultivate large-scale GM tomatoes that have been implanted with the HBV and cholera genes. Compared with bananas, tomato cultivation is better. Tomato cultivation period is relatively short, only about 6 months, easy to widely cultivated, while tomatoes are more likely to produce functional antigen proteins than bananas.
