The discussion centers on the feasibility of creating a tablet containing macrophages to combat viruses. Key challenges include the difficulty of absorbing macrophages through the gastrointestinal tract, where they could be broken down or pass through without effect. An alternative method of injection, similar to vaccines, is suggested, but concerns arise regarding the potential for the body to reject non-matching artificial macrophages as foreign invaders. Additionally, the need for custom-built macrophages for each individual raises significant technical and practical barriers, making the concept unlikely to be viable.
