Phages are being researched. This literally comes up in every single HN thread on antibiotics, so once more, posting my "Why Phages Aren't the Answer" shortlist. Note that I love phage therapy - this is the problems as seen by someone who doesn't think it's a dead end: Phage therapy is neat, it really is, but there are a couple major issues: - There is no such thing as a "broad spectrum" phage. You can't do empirical treatment using phages, and there's not really "off the shelf" phage therapy - it tends to be a bespoke creation for a particular infection. - There's some serious regulatory problems, similar to those experienced by fecal transplant treatments. We're not yet really equipped to think about handling evolving, custom microbes as a treatment. - Because of the first, it's going to require a considerable amount more lab capacity than most clinical settings currently have, and considerable delays until treatment. - There's also some biosafety issues around phage prep, but those are easily solvable. It's a great way to treat particularly resistant or hard to treat infections, but it's not a particularly great general solution. There's a reason it was abandoned in countries with easy access to antibiotics - they're just roundly superior in basically every respect.
