Why are we talking about vaccinated vs unvaccinated children again?
Brian Hooker published a study non-peer reviewed preprint comparing health outcomes between vaccinated and unvaccinated pediatric populations.
And no, you won’t be surprised by his results.
Let’s Talk About Vaccinated vs Unvaccinated Children Again
Wait, why won’t you be surprised?
Mostly you won’t be surprised because of all of the errors in his preprint!
What else?
Hooker doesn’t consistently define what it means to be unvaccinated.
In this study, for some children, unvaccinated may mean:
zero vaccines, or
first vaccinated after 13 months
I mean, are they really unvaccinated if they got caught up after 13 months?
And that’s not all!
“Strep infection demonstrated the strongest association in the primary analysis.”
Comparative Health Outcomes of Vaccinated versus Unvaccinated Children: A Retrospective Cohort Analysis
For the clinical condition that was supposedly most associated with having been vaccinated, strep infection, they didn’t just use the classic strep infection diagnostic codes!
Instead, we have codes for everything from infectious mono and gonococcal infections to sexually transmitted chlamydia diseases.
And we have codes in categories that are totally out of place!
R19 codes are for conditions that involve GI symptoms, not respiratory disease.
Were these codes deliberately selected to influence the results of the study preprint?
Lastly, the study doesn’t account for things like daycare attendance, prematurity, breastfeeding, socioeconomic circumstances, or household smoking, etc.
They didn’t even control for healthcare utilization.
Also, why did he choose those common pediatric conditions, but leave out cough and diarrhea?
Maybe he will release the data so that we can analyze it ourselves!
Until then, know that this bombshell study that is being laundered by anti-vaccine influencers across their social media accounts and websites is worse than just another dud. It is more obvious propaganda than they usually put out!
In case anybody is wondering about the Zenodo publication, it's:

Thanks for this and a nod towards StopAntiVaxPropaganda Substack
vaxopedia.org, nope, no surprises here. Cutting though the bovine excrement is a consuming task. So, to the end point, jr did say “We are doing the studies to make the proof.” Of course, it was about Acetaminophen but I don't they are stopping there.
