Vaccines and Data
Nov. 5th, 2009 02:46 pmThe Atlantic has an interesting article on the issues surrounding influenza vaccinations. Makes a pretty good case that the flu shots don't have much effectiveness in keeping people from dying. There's a rebuttal out, of course.
The scariest part for me is the poor quality of the data on flu deaths. Diagnoses are based on symptoms, not tests of the virus, so we don't actually know how many people have been getting sick or dying from influenza. No one's doing well designed experiments to test the effectiveness of the vaccine and one of the big arguments (herd immunity) would be damned hard to test in any case.
I suspect we're not going to have a real grasp of the effectiveness of medical treatments until we give up on the privacy of medical records. If we get to the point where everyone's records are searchable, and detailed to the point where you can tell if a swab test was H1N1 positive or the doc just wrote a prescription to make the patient go away, there's going to be a lot of patterns discovered that'll make irrelevant all the watch-36-patients-for-six-months microstudies that policies get based on now.

Date: 2009-11-10 01:08 am (UTC)One of the worst fallouts in the vaccine-causes-autism scare is the unwillingess of either side to play rationally (generally speaking: I'm fortunate to have a sensible pediatrician, myself) Limiting vaccines to children under 2.5 years of age (when autism appears) in families with a history of Aspergers spectrum disorder would be an obvious way to manage fears while deligitmizing the luddite/scientific illiterates. Can you believe that there are grown women arguing that adults shouldn't get a flu vaccine because it could cause autism? Oy!
I get the flu shot because I'm a healthy workaholic who serves the public--the odds I'd get infected, or more likely infect someone else because I didn't distinguish between "just a cold" and "golly, I'm really sick" is darn likely. There's a whole cohort of healthy individuals who can, by being resistant, help prevent the spread of disease. We who can, should.

Date: 2009-11-10 03:37 pm (UTC)As for which kids should get fewer vaccines I'd think a family history of autoimmune disorders should be a bigger warning flag than autism spectrum ones. But I have yet to find a doctor willing to deviate from the prescribed shot schedule. Skip entirely, yes, but not slow it down or just do the most crucial ones.

It's as if being so smart, educated and knowlegeable in one area innoculates them from a useful humilty viz their powers in every other subject.
Next time I see my pediatrician I'll have to ask her why she was so willing to adapt the Mighty Mite's vaccine schedule to my needs (I have both a history of autoimmune disorders and Autism spectrum: I did not want to take chances with my baby!) We delayed, skipped--we'll be fully up to speed by the time the kid is 10 and in the meantime, she's got the most critical covered. I wish more doctors would evince her compassion and common sense.
