Costs and ease of use

Bacterial immunotherapy treatment consists of administering live or dead bacterial cultures to an affected cancer patient in order to trigger an immune response against both the bacteria as well as cancer cells. 

Manufacturing
Many bacteria can be cultured easily (although doing so according to GMP guidelines is a requirement for bacterial immunotherapy products).

Clinical use
Patients receiving bacterial immunotherapy treatment are expected to develop fevers and can possibly suffer from more severe symptoms resulting from the microbial colonisation / infection (see Safety). Bacterial immunotherapy treatments can thus be given by hospitals that have the infrastructure required to deal with problematically severe reactions. The required infrastructure is expected to be available in both developed and developing countries. 

Costs of bacterial immunotherapy will be low. In for instance a Japanese study the costs of BCG therapy were reported to be $1936 per patient and $525 per recurrence free year after treatment.

Given both its low costs and ease of use, bacterial immunotherapy promises to become a feasible and effective treatment option for many patients world-wide.
