Civil Scientific Discourse RIP

It’s no secret that I am not fond of hot weather in general and summer in particular. Making me especially cranky at the moment is the hyperbole surrounding the science/non-science discourse, e.g., around childhood diseases like chicken pox or measles, mumps and rubella (the three dire conditions the MMR vaccine is supposed to prevent). The crux  appears to be that either you’re either one of those unscientific, Jenny McCarthy-quoting, loons who believes vaccines causes autism – or you’re a normal, nice, sane person who believes in science. Paradoxically, science appears to have gained the status of a deity in this discourse.

No need to get hysterical about skepticism.

No need to get hysterical about skepticism, Hume might way.

Case in point, a headline last year: “Shun anti-vaccine talk, SFU urged”. Some anti vaccine conference was going to take place at some SFU campus and an angry group of critics were whopping mad lest this event “lend credibility” to this “dangerous quackery”.  This, er, quackery was some symposium where the discussion was on how “families are facing increasingly intense pressure from the vaccine lobby and big government to comply with vaccine mandates” and was  organized by something calling itself the “Vaccine Resistance Movement”. Hardly saving the free world from tyranny but hey, the resistance carries on, large as life and flakier than thou.

The 18th century philosopher David Hume, the granddaddy of skepticism would no doubt be turning in his grave at this hysterical, humourless assault.

BC’s Chief Medical Officer replied in his usual vein: “Vaccines, like any medicine, can have side effects, but the benefits … outweigh the risks,” Which is true. But in the abstract one can  wonder whether suppressing all childhood diseases may perhaps have immune consequences. Especially the trend towards vaccinations against diseases “such as chicken pox which cause only inconvenience rather than danger” in the words of British sociologist and science and technology writer Trevor Pinch. (In Dr. Golem: How to Think About Medicine by Harry Collins and Trevor Pinch, University of Chicago Press, 2005). Especially given the sheer number of jabs (approx. 20 I think) that infants now get.

SFU president Andrew Petter apparently refused to cancel anything, merely saying universities stand for freedom of expression and, as far as I know, the conference went ahead. I have no idea what was discussed but I suspect it was a lot of nonsense. That’s not the point. What’s perturbing is the vitriol of the protesting group and the smug suggestion that if one dares to question the “science” or wonder out loud if these might, just might, have adverse immune or other effects, one has no right to speak. Either you toe the party line or you’re a crazy person. One who should be run out of town on a rail to coin a phrase. (I’ve never been sure why being run out on a rail – which to me implies a train – would be such a bad thing. Personally I am mega fond of trains.)

The photo of the conference protestor indicates that the group (“The Centre for Inquiry”) is just as obscure as the one they’re protesting. Maybe the whole thing was a publicity stunt or performance art, who knows.

Any child not vaccinated against the measles should not be allowed in school, someone firmly said to me last month. Measles can cause deafness and blindness, not to mention encephalitis, someone else said. I mildly agreed, merely pointing out that the numbers on these dire effects in the developed world were actually vanishing small, at least based on the (admittedly limited) research I had done. Buried in the contradictory numbers one small group of children was clearly at risk from measles, namely children undergoing cancer treatment.

Years ago, when I wrote a book on the immune system, I did a bit of desultory research on measles; there was some evidence that a natural bout of measles appears to reduce the incidence of allergies and asthma in later life. (Operative word appears – the data was correlational and based on medical records; there is no way to know for sure if this was cause and effect. Bearing in mind that many health recommendations, e.g., lowering cholesterol, are based on correlation.)

Immunologically measles might have a modulating effect; in a way allowing the immune system to become less inappropriately reactive and reducing the incidence of asthma and allergies or other auto-immune conditions. Perhaps this struck a cord with me because in my own case a natural bout of German measles (rubella) cleared the bad eczema (also an auto immune over reaction) I had suffered since I was two or three. Large, itchy welts covering my legs, arms and face, especially knees and elbows. Then poof, I get sick when I am nine or thereabouts; high fever and whatnot, and my eczema essentially clears. I still occasionally get eczema, usually in reaction to an allergen (like aloe). But, by and large, I’m fine. The research I did years later gave me a context for that (better than my grandmother’s “well, the high fever burned it off” which made the eczema sound like a forest fire – though, come to think of it, that’s not the worst description).

But when I wondered out loud some weeks ago if maybe, maybe, over zealous vaccination programs could have anything to do with the increase in peanut allergies some months ago you’d have thought I had suggested a plot for Criminal Minds. It was speculation, people. I’m not the vaccine police.

I’m not sure quite how this binary, myopic perspective evolved and became so engrained, but it seems now that any questioning of standard medical dogma (““sugar is bad”) ends up as some version of t’is/t’isn’t, t’is/t’is NOT: all the subtle dynamics of a nursery school. Either you’re a feeble minded dweeb who fell for the fraudulent, discredited Wakefield Lancet article linking vaccines with autism (actually GI problems not autism but that’s lost in the mist of rhetoric) – or a sensible, right thinking person who believes in science, good government and iPhones. (As it happens I now have a Blackberry Z10 which I think is far, far superior. Were we to pause for a commercial break.)

Science is a method. Science is fluid, moves forward asking questions and trying to find empirical evidence to back them up. It is not dogmatic or static. It’s not perfect but at this point it’s the best we’ve got. But I guess if you’re going to turn science into a religion then it will end up that way.

Pity, since scientific inquiry was, to a large extent, what dragged us out of the Dark Ages.
