Tedd Koren, DC is an exception to the anti-vaccinationists in that he has a health degree, in chiropractic, although from Sherman College, the "straightest of the straight" (and the least committed to legitimate science) of the chiropractic colleges.

Dr. Koren practices very little chiropractic as such, but instead operates Koren Publications, Inc, based in Philadelphia.  The inventory of Koren Publications includes posters, brochures, audio and video tapes, and assorted books aimed at the chiropractic market.

Dr. Koren dispenses a brand of pseudo-religious zealotry claiming chiropractic spinal 'adjustments' can cure virtually every ailment known to man, including cancer.   He is especially noted for dispensing a poorly written, unscientific, and miserably researched series of paperbacks, written by laymen, alleging virtually all social and health illnesses known to mankind are attributable to vaccines.

His materials attempt to make up in  gloss and hype for what they lack in scientific credibility.  In June, 1994 Consumer Reports produced an article on chiropractors.  While noting both benefits and drawbacks to chiropractic care the article uniquely singled out Koren's materials and described them as: "Filled with misinformation about standard medical care . . ."

Examples of Dr. Koren's strange claims and approaches to health care include the following:
   *  The primary cause of female breast cancer is the
       wearing of brassieres!     Ref
   *  The cause of AIDS is not HIV.  Instead AIDS is just a form
       of syphilis - and is treatable with typhoid vaccine!
       (Ref:  AIDS is really syphilis? Tedd Koren, The Chiropractic Journal July 1995 V. 9 No. 8
           Koren's primary reference for this claim is AIDS and Syphilis:The Hidden Link, by Harris Coulter)

Despite countless instances of feedback from his own colleagues that his materials were substandard, Dr. Koren has chosen sloppy science over honest portrayals of scientific evidence.
