As scientists run out of defences against deadly drug-resistant superbugs, research is turning to bacteria’s ancient enemy, bacteriophages, to fight disease.

From pioneering clinical trials in the USA to phage hunts in Kenya, The Good Virus visits the frontlines of research into this radical therapy, to reveal how everything from medicine to agriculture is being revolutionised.

With CGI, and on-the-ground access to global experts including Yales' Ben Chan, this is the global story about an urgent scientific fight to save lives with “phage therapy,” a good virus.
