Sudden infant death syndrome (SIDS) is any sudden and “unexplained” death of an apparently healthy infant aged one month to one year. The term cot death is often used in the United Kingdom, Austrailia and New Zealand, and crib death in North America. SIDS is responsible for roughly 50 deaths per 100,000 births in the U.S.
When the Japanese changed their pertussis immunization policy in 1975 the phenomenon of Sudden Infant Death Syndrome “completely and immediately disappeared.”
Between 1970 and 1974, 37 infant deaths occurred after DPT vaccination in Japan; because of this the doctors in one prefecture boycotted vaccination (Iwasa et al. 1985 and Noble et al. 1987). Consequently, the Japanese Government first stopped DPT vaccination for 2 months in 1975, and, when vaccination was resumed, the vaccination age was lifted to 2 years.
Cherry et al. (1988) found it “instructive” that the entity of cot death then “disappeared.”
Japan zoomed from 17th to first place in infant mortality in the world. This means that Japan moved from a very high bracket to the lowest infant mortality rate in the world (Scott 1990). Interestingly, Noble et al. (1987) who spent some 2 weeks in Japan studying the acellular whooping vaccine there, wrote: “It is difficult to exclude pertussis vaccines as a causal factor even when other etiologies are suggested, particularly when the adverse events occur in close temporal association with vaccination.”
Can a reasonable person still maintain that vaccination has nothing to do with Sudden Infant Death Syndrome?
Recently, a causal associations was proposed along with the aforementioned facts, and a medical doctor responded by saying “vaccination does not cause SIDS, it’s just that you see SIDS around the time that kids get vaccinated.
