I am trying to determine fact from fiction regarding vaccinations. I am strongly in favour of them. Are there ANY reliable doctors/scientists/immunologists anywhere in the world that support not vaccinating? I have found none. Dr. Sherri Tenpenny is regulary featured in the Huffington Post, and is against vaccination, or at least states she is pro-choice. From what I can gather, she is an osteopath, with no authority on immunology whatsover. That said, why would the Huffington Post describe her like this: Dr. Sherri Tenpenny is respected as one of the country's most knowledgeable and outspoken physicians regarding the negative impact vaccines can have on health. In addition to vaccines, Dr Tenpenny is an expert on many topics within the field of Integrative Medicine.
