The Revolutionary Claim by He Jiankui
He Jiankui’s Announcement
In November 2018, Chinese scientist He Jiankui shocked the world by claiming that he had created the first genetically edited babies. He announced that twin girls, named Lulu and Nana, had been born with edited genes aimed at providing resistance to HIV. This revelation ignited a global debate about the ethical implications of genetic editing in humans.
The Method and Science Behind It
He Jiankui employed a technology known as CRISPR-Cas9, a powerful method for editing genes that allows researchers to precisely alter DNA. His intention was to disable a gene called CCR5, which is the entry point for the HIV virus. While the science behind CRISPR holds immense potential for treating genetic disorders, He’s application of it in embryos raised alarms regarding its safety and the long-term consequences.
The Global Reaction and Ethical Concerns
Scientific Community's Backlash
The announcement was met with widespread condemnation from the scientific community. Many prominent scientists deemed He’s experiment as reckless and unethical, pointing out that the long-term effects of germline editing (which is passed down through generations) are still largely unknown. Leading organizations such as the National Academy of Sciences emphasized the need for stringent regulations surrounding germline editing.
The Chinese Government's Response
In response to the uproar, the Chinese government launched an investigation into He Jiankui's actions. The event prompted a reassessment of regulations regarding genetic research and experimentation in China. By late 2019, He had been sentenced to three years in prison for conducting illegal medical practices, reflecting the seriousness of ethical violations in biomedical research.
Fun Fact
He Jiankui’s Unique Career Path
Prior to his controversial experiment, He Jiankui had spent several years studying in the United States, which later contributed to his bold approach in China, highlighting the intersection of global science and local cultural challenges.
