South Korean scientists have engineered a bird flu strain 100% lethal in mammals, achieving total mortality in mice. The virus adapted and spread among them, killing even contact cases. Published in Virology Journal (June 2025), the study reveals that just 4% of the virus carried a mammalian-adaptive mutation—enough to dominate and kill all hosts. Meanwhile, the U.S. is pushing a universal “Generation Gold Standard” avian flu vaccine. Critics warn: this isn’t prevention—it’s controlled pandemic prep.
