In April 2000, two children were born suffering from a serious combined immunodeficiency disorder, which forces them to live inside "sterile" protective bubbles. Seeing this, French researchers removed stem cells from children's marrow and inserted genetically modified viruses into them. Two years later, the children are still healthy (Trefil). Gene therapy involves replacing a single faulty gene with a good one to cure a disease. Adding genes that determine the production of the right proteins is also part of the use of gene therapy. There are two types of gene therapies: somatic and germline. In somatic therapies, viruses are used as vectors to deliver genetic material into the body's cells. In germline therapies, sperm or eggs are used (Association). Gene therapy is not only used in medicine, but also to improve foods and crops, for example: “the introduction of genetically modified, pest-resistant cotton varieties in China has reduced pesticide poisonings by almost 80%. %” (Miller). Gene therapy should be widely available to all due to its high success in treating diseases and its great social and economic benefits. Gene therapy has shown much success in treating diseases such as severe combined immunodeficiency disorder and blindness, so it should be available for everyone to use. Gene therapy can be used to treat so many diseases, and there should be no problem stopping scientists from using it to treat cancer or blindness. Gene therapy was used in clinical trials to see how it would help treat cancer, "but Gromeier's team tamed it by inserting a small piece of genetic material from a cold virus into the poliovirus genome, effectively making it 'completely unable to cause polio... injected the hybrid virus into mice with malignant gliomas... center of paper...
