Scientists have recently discovered a new way to fight infection and help increase genetic diversity: genetic engineering. By manipulating the genetic code of certain organisms, scientists can create new strains of bacteria or viruses that are resistant to certain diseases or even act as vaccines. These engineered organisms could then be used to help increase genetic diversity in populations, which could help them become more resilient to disease and better able to survive in changing environments. This could be an invaluable tool in the fight against infections and diseases, and it could have far-reaching implications for the future of human health.
