Today I went to the one-day, 2nd Yale Research Symposium on Complementary and Integrative Medicine. Many of you will recall that the first version of this conference occurred in April, 2008. According to Yale’s Continuing Medical Education website, the first conference “featured presentations from experts in CAM/IM from Yale and other leading medical institutions and drew national and international attention.” That is true: some of the national attention can be reviewed here, here, here, and here; the international attention is here. (Sorry about the flippancy; it was irresistible)
I’ve not been to a conference promising similar content since about 2001, and in general I’ve no particular wish to do so. This one was different: Steve Novella, in his day job a Yale neurologist, had been invited to be part of a Moderated Discussion on Evidence and Plausibility in the Context of CAM Research and Clinical Practice. This was not to be missed.

Children aren’t supposed to die. That so many of us accept this statement without a blink is remarkable and wonderful, but it is also a very recent development in human history. Modern sanitation, adequate nutrition, and vaccination have largely banished most of the leading killers of children to the history books. Just look at the current leading causes of childhood death in developing countries to see how far these relatively simple interventions have taken us.
As we have systematically removed the leading infectious killers of children from prominence, other organisms have naturally risen to the top of the list. This has lead some to the fatalistic (and mistaken) conclusion that we are simply opening up niches to be inevitably filled by other virulent organisms. This assumes that there is some mandated quota of say, meningitis, that children must suffer every year, and if one organism doesn’t meet this quota then another will fill it. Were this the case, after vaccination we’d expect to see a shift in the causes of meningitis, but at best a transient drop in the total number of cases per year as other bugs step in to pick up the slack of their fallen, virulent, meningitis-inducing brethren. Such is not the case.
Though new organisms are now the leading causes of invasive bacterial infections in children, and we have indeed seen some increases in non-vaccine targeted strains, as I’ll discuss below, the total number of such infections has dropped precipitously. It’s fair to say that the vaccination program has done a remarkable job improving a child’s chance of surviving to adulthood in good health. However, no one in their right mind would argue that the current state of affairs, as good as it is, is good enough, and so we have shifted our sights to the current leading cause of invasive bacterial infections in children, Streptococcus pneumoniae (S. pneumo, or pneumococcus).
