The bacteria develop resistance fairly quickly, but you can somewhat get around that with cocktails of phages (like a bunch of phages at once).

> For a sick person after antibiotics therapy and after culture test results, those days/weeks to raise another culture of phages might be deadly

The hope is that you'd have a bunch of phages ready to go from a variety of patients. So you wouldn't need to make a new culture. However, right now they often do personalized phage therapy because they can only get it approved as a last-hope kinda deal. But then it makes the scientists only target chronic infections, because it does take a couple months to get another cocktail of phages ready to go.
