I suppose that they could work if they were made to just treat one disease. What's good for one thing just might be deadly for another.

Friendly Viruses Protect Us Against Bacteria. Bacteria can be friends and foes—causing infection and disease, but also helping us slim down and even combating acne. ... "We don't have all that many examples of beneficial viruses." One of our most important lines of defense against bacterial invaders is mucus.

Yes, indeed. We need friendly bacteria, for example, in our gut to help digestion. That's why antibiotics often cause diarrhea as a side effect, killing 'good' as well as 'bad' bacteria.

If phages can be targeted only on specific 'bad' bacteria, that would be excellent.


Very true.  Scientists are working on ways to better control the "friendly" virus types to make them even more predictable and useful for medical purposes.
