"But it is not only in ancient history that we find compelling evidence that nosodes can and do provide effective immunization. Take Polio as an example: 1850-Taylor Smith in Johannesburg, South Africa immunized 82 people with "Lathyrus". 12 of the 82 were in direct contact with disease in an epidemic area. There were no cases reported in any of the 82-a 100% success.
More recent times-Grimmer in Chicago `vaccinated' 5,000 young children with "Lathyrus". None of them developed polio.
Heisfelder, in a study between 1956-58, immunized over 6,000 children with this nosode. There were no side effects and no cases of polio.
In 1975, during a polio epidemic in Buenos Aires, "Lathyrus" was given to 40,000 people. Not one of these developed polio."
