I don’t think it’s fair to say there is a lack of awareness that bacteriophages-as-concept exist. Most curricula in medical school will touch on these. However, what is more of a realistic lack of awareness is the ability to request bacteriophage therapy for a specific patient. It’s not something that has been thoroughly vetted or solved as a scalable solution because there’s a lot of technical hurdles. The closest approved therapy that is somewhat similar to what phage therapy would involve is CAR-T cell creation, and this is wildly expensive and resource intensive. To give a somewhat comparable example, it’s more like someone saying asking why the average programmer doesn’t know anything about quantum computers as a solution for critical cryptographic problems.
