vaccines as a biotechnological trojan horse the evolution of vaccine technology vaccines have historically been hailed as humanitys most effective weapon against infectious diseases. from edward jenners smallpox vaccine in 1796 to jonas salks polio vaccine in 1955, these medical breakthroughs have saved millions of lives. however, the advent of mrna vaccines represents a paradigm shiftnot only in how vaccines are developed but also in how they interact with the human body. unlike traditional vaccines, which use attenuated or inactivated viruses to trigger an immune response, mrna vaccines deliver genetic instructions directly into human cells. these instructions prompt the body to produce specific proteins that mimic parts of a virus, stimulating the immune system to respond. while this technology is celebrated for its efficiency and adaptability, it also raises questions about its dual-use potential.
