Interesting....
But let’s start from an objective baseline. The CDC Guidelines would have a baby get 21 vaccines by six months of age.
With vaccinations being so universal as every child is required by law to have them it seems it would be very difficult to get a control group of unvaccinated children.
Especially pronounced in preterm infants which definitely warrants further investigation. This goes beyond vaccinated children simply getting more doctor visits (although that could certainly factor into the correlation).
Is some of this because you get more money the more ‘disabled’ your kid is?
Vaccinations required for school attendance have increased nearly threefold since the 1950s, now targeting 17 infectious diseases. However, the impact of the expanded schedule on children’s overall health remains uncertain. Preliminary studies comparing vaccinated and unvaccinated children have reported that the vaccinated are significantly more likely than the unvaccinated to be diagnosed with bacterial infections, allergies, and neurodevelopmental disorders (NDDs). The objective of this study was to determine the association between vaccination and NDDs in 9-year-old children enrolled in the Medicaid program. The specific aims were to test the hypothesis that: 1) vaccination is associated with autism spectrum disorder (ASD) and other NDDs; 2) preterm birth coupled with vaccination increases the odds of NDDs compared to preterm birth without vaccination; and 3) increasing numbers of vaccinations are associated with increased risks of ASD.
Results: The analysis of claims data for 47,155 nine-year-old children revealed that: 1) vaccination was associated with significantly increased odds for all measured NDDs; 2) among children born preterm and vaccinated, 39.9% were diagnosed with at least one NDD compared to 15.7% among those born preterm and unvaccinated (OR 3.58, 95% CI: 2.80, 4.57); and 3) the relative risk of ASD increased according to the number of visits that included vaccinations. Children with just one vaccination visit were 1.7 times more likely to have been diagnosed with ASD than the unvaccinated (95% CI: 1.21, 2.35) whereas those with 11 or more visits were 4.4 times more likely to have been diagnosed with ASD than those with no visit for vaccination (95% CI: 2.85, 6.84).
Conclusions: These results suggest that the current vaccination schedule may be contributing to multiple forms of NDD; that vaccination coupled with preterm birth was strongly associated with increased odds of NDDs compared to preterm birth in the absence of vaccination; and increasing numbers of visits that included vaccinations were associated with increased risks of ASD.
Nothing has changed my mind since.
A quick read leads me to believe it is a robust, well designed study.
I could not be certain to rule out selection bias. It appears, for part of the study, they used anonymous responses to an online survey with 666 participants. The online survey data was only one part of the paper presented.
Results from the Florida Medicaid records were much more robust, based on 86K children, of which 13K were not vaccinated. This was further reduced to 43K vaccinated and 5k unvaccinated of the age group desired.
Finally 4,492 vaccinated preterm children were compared to 517 preterm children who were not vaccinated.
At first glance, looks to be a decent study.
Why am I not surprised that children enrolled in Medicaid have higher instances of diagnoses which provide monetary assistance from social security disability programs?
Children enrolled in medicaid are far more likely to come from dysfunctional households with chronic substance abuse problems.
Every pregnant junkie is enrolled the minute they show up at social services to get WIC and more food stamps. Compliance with vaccine schedules is pretty much required. And free at the health department in my state where they often give out free diapers and formula as incentives to keep appointments.
Unvaccinated children are more likely to come from two parent families often well off enough to have a stay at home mommy who doesn’t even use caffeine or ibuprofen while pregnant.
Comparing the two populations and thinking that vaccines are the problem is ludicrous.
