Art Moore wrote in a Dec. 28 WorldNetDaily article:
A study by Danish researchers finds that after 90 days, the COVID-19 vaccines will make you more likely to get infected from omicron, not less.
They may offer a short-term benefit from the delta variant, "but at the expense of a degradation of your overall immunity to everything else," reports Steve Kirsch. a Silicon Valley tech entrepreneur and philanthropist who founded the Covid-19 Early Treatment Fund.
The study shows that after three months, the effectiveness of the Pfizer-BioNTech and Moderna mRNA vaccines against omicron is actually negative.
The Pfizer vaccine makes recipients 76.5% more likely and the Moderna recipients 39.3% more likely to be infected than unvaccinated people.
Moore's mistake here is trusting the word of Kirsch, who is a prolific COVID misinformer. And, indeed, Kirsch is wrong here too, misinterpreting the study data -- which Moore failed to mention was published on a preprint server called MedRxiv, meaning that it has not been peer-reviewed. Meanwhile, a website that, unlike WND, cares about accurate medical information debunked that claim:
Health Feedback reached out to the preprint’s authors for comment. The first author, medical statistician and epidemiologist Christian Holm Hansen, refuted the claim, stating that the “Interpretation that our research is evidence of anything but a protective vaccine effect is misrepresentative”.
He also explained why vaccine effectiveness (VE) was observed to be negative in the study, citing the presence of bias in the VE estimates, saying that “Such biases are quite common in VE estimation from observational studies based on population data”, unlike in phase III clinical trials. Indeed, a preprint
The fact-checker also reported something that Moore didn't -- that the paper "concluded in favor of vaccination, not against it."
Another fact-checker made the same conclusion:
Nowhere does it suggest that vaccinated people are more likely to be infected than unvaccinated people.
"Interpretation that our research is evidence of anything but a protective vaccine effect is misrepresentative," Astrid Blicher Schelde, one of the study’s authors wrote in an email to PolitiFact.
As did one more fact-checker:
A study conducted using Danish data between Nov. 20 and Dec. 12 did not conclude that mRNA vaccines cause harm to immune systems. The preprint found that VE against Omicron is significantly lower than Delta and declines rapidly a few months after the second COVID-19 vaccine dose, but is restored following a booster. Negative VE estimates in the final period against Omicron suggests bias in comparison between vaccinated and unvaccinated populations, a co-author of the study told Reuters.
