A proprietary lipid emulsion containing five vaccines: diphtheria, pertussis, tetanus (DPT), Bacille Calmette-Guerin (BCG), measles, Serratia marcescens and pneumococcal, with potential immunostimulating activity. Subcutaneous administration of the DPT/BCG/measles/Serratia/pneumococcus vaccine activates the immune system and may both abrogate tumor-induced immune tolerance and induce an antitumor immune response, which may eradicate the tumor.
