Measles encephalitis; a successful method of treatment with typhoid vaccine.

During a 12-year period 50 patients with measles encephalitis were treated with typhoid vaccine-45 of them not until they were in a vegetative state. There were no deaths in the treated cases. All except one were clinically normal after treatment was ended. Late in the series it became apparent that after the clinical normal is attained and the electroencephalogram becomes normal, treatment should still be continued until the cortex has been "challenged" repeatedly and the electroencephalogram shown to remain normal. The "shock" element in the treatment with typhoid vaccine was prevented by anticipating and circumventing the unfavorable reactions to the vaccine. It may take 20 to 50 treatments or more with typhoid vaccine to return a patient to normality. Each individual is different and responds in a different period of time.
