Cot-death is no longer a problem of clinical medicine, but is one of medical politics. We have long had the knowledge and experience as to how these unnecessary deaths can be avoided. In the meantime.. to prevent your offspring from becoming a SIDS statistic just make sure that its daily intake of ascorbate from conception on is sufficient. Under this regime the neonate is so robust and healthy that there has never been a case of SIDS among these ascorbate corrected infants, not even a case of respiratory distress during birth.
The evidence for indicting immunisations for SIDS is circumstantial, but compelling. However, the keepers of the keys to medical-research funds are not interested in researching this very important lead to the cause of an ongoing, and possibly preventable, tragedy. Anything that implies that immunisations are not the greatest medical advance in the history of public health is ignored or ridiculed. Can you imagine the economic and political import of discovering that immunisations are killing thousands of babies?
Sometimes I think that the amount of time you live on earth is just an inverse reflection of how good you were in a previous existence. For example, infants who die from SIDs were actually great people when they were alive for real, so they get to go to heaven after a mere five weeks in purgatory. Meanwhile anyone Willard Scott ever congratulated for turning one hundred two was obviously a terrible individual who had many many previous sins to pay for and had to spend a century in his or her own unknown purgatory even though the person seemed perfectly wholesome in this particular world.
