Vaccine study that has people worried is being misinterpreted
This article was originally posted in the Montreal Gazette. Recently, some people have been spreading the idea that getting additional doses of the COVID vaccine increases the risk of catching the virus. The suggestion was made in an opinion piece in the W...

Scared of education, are we?
Too dumb to read. Typical Predditor. The article requires an above retardation level.
Or an above average conspiritard level. Of course pharma companies have a vested interest in a somewhat educated population you absolute numpty they go after graduates for their labs.
Nothing can change the fact that the unvaccinated are at a higher risk:
"That’s why, when CDC adjusts for some of these factors (age and population size), we still see that unvaccinated people are at much greater risk of death and other severe outcomes than people the same age who have stayed up-to-date on boosters. Older people are at greater risk for severe illness and death from COVID-19 than younger people, but vaccines and boosters still lower that risk substantially."
Retardation level confirmed.
The government never tracked the fully unvaccinated.
92% of people dying from severe Covid are dying with 3 Covid shots.
Fake news
McGill.ca - one of Ontario's top universities. And you say fake news? It's not even news it's empirical evidence laid out.
Or are you referring to every piece of garbage V&C has spoon fed you to bring you to this point?
The vaccinated retard thinks McGill is in Ontario? Holy shit,
Retardation double confirmed. No wonder you’re vaccinated
Ah, McGrill, counts Gerry Butts and Sparklesox as Alumni. BTW they are in Montreal, not Onterrible.
Ah mb Ontarioian bias
Still though, v&c uses the fallacy everyday like it means anything.
Diversity is not your strength 👎🏾👎🏾👎🏾
However, it would seem as if most people have not actually read the paper in its entirety, because what it actually found was that the bivalent vaccine reduced the risk of getting infected with COVID-19.
First, it’s worth explaining what we mean by a preprint. Most scientific research is presented at scientific meetings and published in scientific journals. Preprints are scientific manuscripts uploaded to the internet without any external peer review. The potential for problems was illustrated back in 2021 when a University of Ottawa study suggested that the rates of post-vaccine myocarditis were several-fold higher than previously reported. That assessment was wrong. The researchers had miscalculated the number of vaccine doses administered in Ottawa during that time. They eventually took down the paper, but not before it was widely shared and fuelled a fair bit of vaccine hesitancy. While peer review has its share of issues, at least it protects against easy-to-spot errors and misinterpretations.
The Cleveland Clinic study is such a preprint. But even if we put concerns about preprints aside, this one fundamentally does not support the things people are saying it does. It does not say that the bivalent booster increases the risk of catching COVID. The top line results show that the bivalent booster reduced COVID infections by 30 per cent. This result is supported by a recent New England Journal of Medicine analysis that found the bivalent booster was better than the original vaccine and had an effectiveness of 59 per cent against hospitalization and 62 per cent against hospitalization or death.
The claim about vaccines making things worse stems from some of the secondary results and appears to fall victim to an epidemiological concept called the Table 2 fallacy. The name comes from the convention that Table 1 in most papers presents the characteristics of patients and Table 2 looks at the relationships between various factors and the end result being studied.
Here’s an illustrative example. If you were studying whether people who carry lighters are at increased risk for lung cancer, you would have to adjust for smoking status. People who carry lighters are indeed more likely to get lung cancer. But if you adjust for smoking status, then obviously, it’s not whether someone carries a lighter per se that predicts lung cancer risk. Conversely, if you wanted to see whether smoking increased the risk of lung cancer (by comparing smokers to non-smokers), the presence or absence of a lighter in someone’s pocket shouldn’t affect the results all that much.
The Table 2 fallacy states that you should not assume that all factors should be adjusted for in the same way. If you want to study lighters, you should adjust for smoking. But if you want to study smoking, you don’t really need to adjust for lighter ownership. These relationships are not interchangeable.
So, if researchers want to study the benefits of the bivalent booster, they should adjust for prior vaccination. But the same formula cannot be used to tell you anything about the protective or harmful effect of prior doses that you adjusted for. It is a subtle but important mathematical principle that is often overlooked. Because if you want to study the number of prior doses, a much more important variable to consider is the timing since your last dose, which is probably more important.
