Coley's Toxins / Bacterial Immunotherapy
Dr William Coley (1890s) first observed that cancer patients who developed erysipelas (bacterial) infections sometimes experienced complete tumour remissions. He developed a mixed bacterial vaccine (Coley's Toxins — Streptococcus pyogenes + Serratia marcescens) that induced therapeutic fever (40–41°C), activating massive anti-tumour immune responses. Considered the historical predecessor of modern immunotherapy. Still used at select clinics, with documented complete remissions in sarcomas, lymphomas, and solid tumours.
Mechanism of Action
Bacterial lipopolysaccharides (LPS) and cell wall components activate toll-like receptors (TLR-4, TLR-2) triggering a massive pro-inflammatory cascade: IL-1, IL-6, TNF-α, and interferons. The resulting therapeutic fever (>39.5°C) directly kills cancer cells (more heat-sensitive than normal cells) and activates NK cells, CD8+ T-cells, and dendritic cells. This is essentially stimulated innate immunity — the original approach to cancer immunotherapy.

Protocols & Dosing
Coley's Fluid (MBVax) Injections
Standardised preparation from MBVax Bioscience — graduated dose injections 2–3x per week at integrative oncology clinic. Start at very low dose, escalate to achieve therapeutic fever (39–40°C). 6–12 month course typical.

Cautions & Contraindications
- May cause severe systemic reactions (high fever, rigors, sepsis-like response) — clinical supervision mandatory
- Contraindicated in heart disease, lung disease, compromised organ function
- Only available at specialised integrative oncology clinics with proper training
- Not for patients on corticosteroids (suppresses the required immune response)
- Controversial — no modern Phase III RCTs; evidence from historical case series only
