There seems to be a scandal brewing at the
CDC about a study that may have shown a devastating link between a vaccine and
autism, especially in African-American children. Depending on who you read,
it’s either a huge deal, or it “may” have “altered” an “interpretation” of the
data “in some instances” leading to an “implication” that “maybe” there’s a
link “in some cases.”
In short, either it’s bad, or it’s a minor
statistical quirk that should be ignored. Naturally, “conspiracy” themed sites
lean towards bad, while official government/mainstream news lean towards the
“nothing to see here, move along” interpretation.
Before discussing vaccines, I want to talk
about tobacco.
--Freud
knew smoking and cancer were related in 1923. That’s over 40 years before
surgeon general’s warnings appeared on cigarette packages. You really think
Freud was the only one to know?
See, everyone knew smoking was bad for
you, long, long, before the government managed to overcome the tobacco lobby
long enough to admit, that, yeah, there’s a problem with tobacco products.
Taking decades to figure out the obvious
is really a problem with modern science, especially when it’s government-controlled.
Pre-colonial American Indians also knew tobacco was bad, but they still smoked.
American Indians, despite not having advanced scientists or a government to
protect them, figured out that smoking can take decades to kill you; thus only
the elders of the tribe were allowed to smoke, generally on special occasions—if
you’re unlikely to live more than a few more years, the potential harm from
smoking drops off sharply. For most of America’s history, if you wanted honest
advice about smoking, you were better off asking American Indians (“in
moderation, the old can do it, the young should not”) than government
scientists (“smoke all you want, start young!”).
In regard to vaccines, the government is
saying “vaccinate as much as possible, start young!” On the other hand, the natives are starting
to whisper there’s a problem here.
People would like honest advice about
what to do. “Everyone knows” something’s wrong with our children’s health, and
the finger is getting pointed at vaccines. Now, just because “everyone knows”
it, doesn’t mean it’s true. That’s why we use statistical and scientific tests
to get a better approximation of the truth than just what “everyone” says.
--there’s a huge conflict of interest
between the people selling the vaccines and the government. It’s reasonable not
to trust the government saying the vaccines are safe, just as it was reasonable
not to trust the tobacco industry when it said smoking was safe.
Unfortunately, statistical tests can prove
nothing. All they can do is give a probability that one assumption or the other
is true, and ultimately, it’s going to be a personal decision as to whether the
test shows there’s a link, or shows nothing. With enough money on the line, a
personal decision can be anything, which is why tobacco executives, for years,
saw no problem with selling their wares…conflicts of interest can cloud
judgment.
And now back to vaccines. There are two
camps, with lots of people in between:
The pro-vaccine camp claims, vociferously:
“all vaccines are always safe for all people under all circumstances.” These
people get annoyed when anyone questions this claim. I exaggerate, but not as
much as I could hope; lots of folks really hate the idea that vaccines aren’t
perfectly safe for everyone.
” I've talked to a health care worker
at a nursing home and they call flu shot day, "culling day."
--Just because nursing home workers
see it with their own eyes, doesn’t make it true. I guess.
So, the claim is vaccines are perfectly
safe. This is an extraordinary claim, and thus requires extraordinary evidence.
None has ever been given, although the simple fact that tens of millions of
vaccines are given every year, and we “only” have tens of thousands of
deaths/serious injuries that “might, maybe” be related to vaccinations, means
that vaccines aren’t particularly deadly—vehicles kill far more people, after
all.
The pro-vaccine camp also points out that
many diseases have disappeared after vaccination, most especially smallpox.
This is quite true, although horsepox has also disappeared, and this related
(but different!) disease never was targeted by a vaccination campaign; horsepox may even be extinct now...but there never even was a
vaccine for it, much less an eradication campaign. Obviously, just because a
disease isn’t as common as it once was, doesn’t mean there must have been a
vaccination program that got rid of it. And, even if the smallpox vaccine is
safe, that doesn’t automatically make all other vaccines safe.
The anti-vaccine camp claims “there’s
something wrong with the vaccines, at least sometimes,” and, for my next essay
or two, I’ll append, “especially when it comes to autism” although vaccines
have also been claimed to be linked to other ailments.
This strikes me at not nearly so
extraordinary a claim, but I’ll present arguments against it. Diseases come and
go, which is what one could say about horsepox…but autism isn’t a viral disease
(as far as we can tell), and parents really seem to notice that their children
“turns” autistic shortly after vaccination—much like American Indians noticed
it took years of smoking before someone died of a hacking cough. Of course,
anecdotal evidence, even when it numbers in the thousands, still doesn’t count for much in a
world of science.
It’s the modern world, a world of
science, and that’s what we should use to make our scientific decisions about
the scientific practice of vaccination.
Autism rates have been shooting up
dramatically, up over 1,000% percent in the last 40
years. Yes, 1,000%
(A quick warning about the many links: often the autism rates are different in
each link; autism rates are up 30% in the last 2
years, so “old”
links from wayyyy back in 2012 are obsolete in this regard). A 10-fold increase
in my lifetime.
Vaccination rates have also been shooting
up, a child today receives about 70 vaccine doses before he’s 18…compared to the half dozen or so
doses I received as a child, this is also an over a 10-fold increase.
This still proves absolutely nothing. Let
me just go over a few reasonable counter-arguments:
We eat more microwaved food than 40 years
ago, and are surrounded by far more electronics as well (I’m looking at you,
cell phones!). We don’t exercise as much as we used to. We wear more synthetic
clothing, our food is more heavily processed…the list of changes in how we live
over the last 40 years is extensive. It’s very natural to blame a new, bad
thing on something else that is new.
In addition, autism was so rare decades
ago that it probably was misdiagnosed as mentally disabled in some other way.
And, it’s quite possibly being over-diagnosed today (much like the hideously
over-diagnosed Attention Deficit Disorder, which many of my students claim to
have, but only one had any symptoms that I could discern…over the course of 25
years of dealing with ADD students). It’s possible, maybe, that autism has
always been far more common than we thought…or that it’s not as common today as
we’ve been told.
All that said, mainstream media continues
to say things that are flat out wrong, and to overlook real, scientific,
evidence that very strongly suggests that, indeed, not all vaccines are always
safe for all people at all times.
A recent CNN article, with some seriously
misleading reporting, prompted me to write about this. Above, I’ve presented
the best case I reasonably can for the pro-vaccine crowd, by way of Devil’s
advocacy: people tend to believe what they’ve read first.
Obviously, you must follow your heart when
it comes time to vaccinate you or your children. Next time, however, I’m going
to look at that CNN article, make some corrections, and present some unarguable
facts of the matter.
