Taken from http://www.shirleys-wellness-cafe.com/vaccine_sids.htm I'm going to copy and paste a few points from this article, but I encourage you to take some time to read more info on the site.

In a recent scientific study of SIDS, episodes of apnea (cessation of breathing) and hypopnea (abnormally shallow breathing) were measured before and after DPT vaccinations. "Cotwatch" (a precise breathing monitor) was used, and the computer printouts it generated (in integrals of the weighted apnea-hypopnea density -- WAHD) were analyzed. The data clearly shows that vaccination caused an extraordinary increase in episodes where breathing either nearly ceased or stopped completely. These episodes continued for months following vaccinations. Dr. Viera Scheibner, the author of the study, concluded that "vaccination is the single most prevalent and most preventable cause of infant deaths."
"These data show that DPT vaccination may be a generally unrecognised major cause of sudden infant and early childhood death, and that the risks of immunisation may outweigh its potential benefits. A need for re-evaluation and possible modification of current vaccination procedures is indicated by this study." William C. Torch, M.D., Director of Child Neurology, Department of Paediatrics, University of Nevada School of Medicine
*Dr Mendelsohn, M.D. - "My suspicion, which is shared by others in my profession, is that the nearly 10,000 SIDS deaths that occur in the United States each year are related to one or more of the vaccines that are routinely given children. The pertussis vaccine is the most likely villain, but it could also be one or more of the others."
*Harris L. Coulter, PhD. - "Crib death" was so infrequent in the pre-vaccination era that it was not even mentioned in the statistics, but it started to climb in the 1950s with the spread of mass vaccination against diseases of childhood."
Japan changed the start time for vaccinating from 3 months to two years and straight away their SIDS rate plummeted. "Delay of DPT immunisation until 2 years of age in Japan has resulted in a dramatic decline in adverse side effects. In the period of 1970-1974, when DPT vaccination was begun at 3 to 5 months of age, the Japanese national compensation system paid out claims for 57 permanent severe damage vaccine cases, and 37 deaths. During the ensuing six year period 1975-1980, when DPT injections were delayed to 24 months of age, severe reactions from the vaccine were reduced to a total of eight with three deaths. This represents an 85 to 90 percent reduction in severe cases of damage and death." Raymond Obomsawin, M.D.
