Scientists try to turn HIV’s greatest strength—mutation—against itself
At first it sounds like a terrible plan, the kind that results in zombies ruling the Earth. Imagine a killer virus, a bug that mutates so often that it inevitably finds a way to resist every drug. Now, rather than fight its ability to evolve, you enhance it. You speed up the mutation rate, forcing such dramatic genetic change that the virus crashes completely. In the movies, this technique, known as lethal mutagenesis, would create a supergerm, but in real life it’s spawning a powerful new class of antiviral drugs.
