CDC Study Claiming Unvaccinated Have More Than Double the Risk of Re-infection is Full of Holes

by Will Jones
12 August 2021 1:08 AM

The Centers for Disease Control and Prevention (CDC) in America has published a new study claiming to show that, among the previously infected, the unvaccinated are at more than double the risk of re-infection than the vaccinated.

It forms part of their evidence for why people who have had COVID-19 before should get vaccinated and not rely on natural immunity.

It has a number of problems, however.

The study looks retrospectively at data from the U.S. state of Kentucky. The researchers identify all those in the state who were re-infected during May and June 2021 (defined in terms of positive tests a certain number of days apart) and compare their vaccination rates to a control group. They find 246 re-infections in that period, and calculate that those who were not vaccinated were 2.34 times more likely to be re-infected than those who were vaccinated.

The study has a number of limitations, however, some of which the authors acknowledge.

Firstly, the study period of May and June 2021 is notable for being a period of very low prevalence in the state, meaning it is not a good time to study acquired immunity, which is best studied during a new surge when it is most put to the test. The authors themselves acknowledge that because the study covers just one period in one state, the “findings cannot be used to infer causation”.

The authors also acknowledge that test-seeking behaviour may skew the findings to exaggerate vaccine effectiveness, as vaccinated people are probably less likely to get tested.

Another weakness is that the study doesn’t include symptom data so we don’t know whether the “reinfections” were actual disease or just asymptomatic and mild infections of the kind that are characteristic of the immune system working.

A related problem is that there is no discussion of how big the problem of re-infection is from an absolute standpoint. With only 246 re-infections (of unknown severity) in a population of 4.5 million over a two month period, it’s not clear that even if vaccination did halve your probability of re-infection it would be a difference worth getting vaccinated (which carries its own risks) to achieve.

Another problem with the study is that it may be confounded by a number of factors, not just test-seeking behaviour, but also age, for example.

The main claim of the study (about vaccination-plus-infection giving better protection than infection-by-itself) comes from the fact that the unvaccinated made up 73% of those who were re-infected but only 58% of those weren’t re-infected. But this outcome could easily be skewed by the fact that the young are both less likely to be vaccinated and more likely to be exposed, so that the unvaccinated are ‘over-represented’ in the re-infected. Unfortunately, we can’t get any clue as to whether this is what is going on as the results aren’t broken down by age, so we can’t tell whether the re-infections disproportionately occur in the more socially active and less vaccinated young.

If this is the basis on which the CDC is planning to encourage previously infected young people to get the jab to supposedly enhance their immunity then they should be ashamed of themselves. They should at least state the absolute risk reduction (over a range of prevalence levels) so people have a better understanding of the true level of protection the vaccines are giving them (according to the study), rather than just talking in terms of halving a risk that they fail to mention was very small to begin with.

“The CDC is in bed with Big Pharma”.

This is exactly the sort of thing I mean. A quick internet search threw up this headline. Print these stories if you must, but for goodness sake flag up their links to the people selling these experimental gene therapy drugs. And print some studies from people definitely not linked to the pharmaceutical industry so we can decide for ourselves what to make of the claims by the likes of the CDC. And I ask again, what do studies on the “vaccines” by scientists with no links to Big Pharma (or their proxies) look like compared to those by scientists who are linked? We need to know what differences there are and why. Especially given the history of corruption in and deaths linked to the pharmaceutical industry – and astronomical profits they stand to make from “vaccines”.

Is this too much to ask?

N.B. I suggest this might provide a more balanced view on “vaccines”.

The level of sophistry from the authorities during this period has been quite something to behold.

It increasingly shows that basic honesty, or even the semblance of basic honesty, is no longer a requirement to hold positions of authority.

Exactly. If levels of prevalence were low at the time of the study (say less than 1% of the population being infected) then all of the positive tests (vaccinated or unvaccinated) could well have been false positives.

(copied from ‘Today’s Comments’ but they’ll be gone before midnight):

Looks like the ‘vaccine passport’ is already here, and the ‘fully vaccinated’ are already seeing advantages in the UK. I disapprove of all of this, but wishful thinking isn’t going to make it go away:

“The NHS Covid Pass – or equivalents in other parts of the UK – allows fully vaccinated adults to avoid quarantine when they return from amber-list countries.
The government says more than 30 countries, including Greece and Spain, now accept the NHS pass.

In Wales, double-vaccinated adults no longer have to self-isolate if a close contact tests positive for Covid.

And from 16 August fully vaccinated adults and under-18s in England also won’t have to self-isolate if a close contact tests positive for Covid.”

This raises the question of how ‘the unvaccinated’ are going to be treated, how are they going to be supervised for their quarantine if Test & Trace point the finger at them and say they have been in close contact with a ‘positive’ case? Will employers be made aware of who has been ‘vaccinated’ and who has not been ‘vaccinated’? More Covid marshalls employed by the likes of Mitie/G4S/Serco/Capita, etc?

I thought The Today had stopped printing. 🙂

Vaxport’s here alright, and I can only hope it doesn’t get any worse. I was watching “In the Heat of the Night”, and it’s not a world I want to live in.

I spent a day last week with someone who tested positive, but I’ve got no symptoms, and no big brother smart arse phone, and no “app”, whatever one of those is. I think I might just skip the house arrest…

I’m morbidly interested in what happens there. I suspect they will keep having snap lockdowns until everyone is vaccinated (late 2021). Then they will continue having snap lockdowns.

No exit plan in Oz, no exit plan in the UK, maybe Dr. Mike Yeadon is right, that the United States (or states like Florida and South Dakota) are our best hope.
I can only hope that this will cause people to wake up.

from the most vaccinated country

https://www.jpost.com/israel-news/israel-hits-400-serious-covid-cases-ahead-of-corona-cabinet-meeting-676412

“In an effort to curb an ever-climbing number of new corona cases”…etc

“64% of those patients defined as serious cases being fully vaccinated, compared with 32% who were not.”

“This means that people who are unvaccinated – by choice or because they do not qualify for the shots – will be required to present a negative COVID test before entering swimming pools, gyms, academic institutions, sports and culture events, conferences, museums, libraries, restaurants and hotels.” – doesn’t make sense – if the vaccines don’t stop you spreading it

Nothing of this makes any sense! The people behind this must have some very cleverly hidden secret agenda! is still a claim which doesn’t make sense, either.

Why not accept things at face value? It doesn’t make sense because it doesn’t make sense. Corona-politics are – by-and-large – the absolutely expected outcome of government by hysterical imbeciles chasing an end which cannot possibly be accomplished by whatever phantasy miracle remedies they can come up with.

Ascribing any capability of intelligent action to these people just prolongs their day in the sun.

Morning, rational extremists.

The last article point is the most significant one: the numbers here aren’t significant. They’re too small, and we can’t infer seriousness.

It’s a Potemkin headline, with nothing propping up the façade.

One thing becomes apparent from the many articles, pro and anti vaccine is that no talk of boosters should continue until this experimental stage is complete. Too much conflicting information.

This is NOTHING to do with health.

Even if this study contained even a smidgen of truth- so what? People get colds, sometimes they drag on but we are not really poorly.

How many “positives” were hospitalised?

As a piece of work this so called study is not worth the paper it is printed on.

The authors should hang their heads in shame.

It’s all about CONTROL.

The FDA and other regulators have no choice but granting full approval.
And the boosters are already ordered.
2 shots per person for each of the next 2 years.

once you look at the caveats in the so called paper the smoke and mirrors appear – it’s bullshit on steroids – proper gander – coming from The CDC – possibly the most corrupt institution in the world – Fauci is at the core of this rotten apple which now appears to run the USA – 1. The virus is a highly targeted seasonal flu which is only potentially dangerous for sick, old, and or vulnerable people, 2. There is no definitive diagnostic and the tests are a 1 bullshit, 3. There are proven cheap available treatments and the vaccines are entirely unnecessary and proven dangerous – so take The Science and bin it and look at what is actually going on – profit driven plus ideologue loony bio tech transhumanist utopian hell – ie feudalism via technology

No surprise.
The trials were just as compromised and showed minimal absolute numbers.
In essence, they already showed that a vaccine wasn’t needed at all.
They were also just semi blind, patients knew whether they got the placebo or the vaccine, as Dr. Ziegler stated recently.
The most at risk, the seriously obese were, coincidentally???, solely present in the placebo group, the suspected cases were distributed equally and swept under the table, and the cases within a week after the jab were overwhelmingly in the vaxxed group, and swept under the table.
This is a fraud.
Nothing else.
And it’s not even a very sophisticated one.

Very good, thank you Frank. “The only reason you give the vaccine to children is if you believe in child sacrifice.” (From memory, slight rewording.)
Exactly.
Against every particle of the knowledge of the nature of God brought to us by the steadfastness of steadfast Jews over thousands of years of turmoil and persecution, sometimes worsened by the failures of their own leaders, as now.
Expect persecution of the ultra Orthodox.
Proud to be with them in this tiny experience of what it is to be a pariah.

I am so sick of natural immunity being constantly denied!

My feeling is we will endure another difficult winter as the government are afraid of getting it in the neck for more deaths then any pretence of controlling infections will be given up and natural immunity will stop being denied and mass vaccination will be rolled back. We need to stay strong until spring. It’s easy for me to say this as I am retired and don’t need to earn money so can stay out of the way. I really feel for younger working people in here commenting about their employers and the covid crap they have to face.

There’s really no point examining this classic junk science in detail. Any one-off study is nothing but an anecdote. To be of any scientific value, the same outcome must occur consistently. The reality is such that these results will be published when they happen to be what the people seeking for them want to publish and otherwise, they’ll continue seeking.

Even assuming this was the case (consistent outcome), the statement generated from it is still junk science: A probability is the relative frequency with which a certain outcome of a random selection process will tend to occur, given enough time, eg, when someone keeps tossing a coin, the number of times each side ends up on the top will approximate towards being the same.

There’s no random selection process here, hence, there can’t be a probability and the implied assumption, namely, the future will become was the past was, could be called a wrongism.
