Investigation for broad use is still in very preliminary stages. All of my reading seems to indicate that for most uses, a phage must be developed incorporating the patient's own tissues and targeted at their specific infection. That means there is no drug or phage manufactured and waiting "on the shelf" to be used.
Knowing how medical treatments are developed, I believe this will be limited to critical or compassionate use for at least a few years until a specific process is developed for making this a routine treatment method.
