Gupta, who is a professor of theoretical epidemiology at Oxford, told The Londoner that alongside huge social and educational benefits, the “evidence is mounting that early exposure to these various coronaviruses is what enables people to survive them”.
The Imperial College study published this morning claiming that 3.4 million people ( six per cent of the UK population) have antibodies indicating that they have been exposed to Covid-19 provides no great revelation. The Office of National Statistics (ONS) has already published similar figures suggesting that 6.5 per cent of the population has been infected. Nevertheless, it is yet more confirmation of how irrelevant are the official statistics for Covid 19 cases – and what a nonsense it is to rely on them for policymaking.
According to the Government’s Covid “dashboard”, updated at 4pm on Wednesday, 313,798 people in Britain have had the disease. This is less than one tenth of the number suggested by the Imperial study. In other words, for all Matt Hancock’s efforts to ramp up testing, the vast majority of cases have not been detected.
- Your immune system’s ‘memory’ T cells keep track of the viruses they have seen before.
- New study led by scientists at La Jolla Institute for Immunology (LJI) shows that memory helper T cells that recognize common cold coronaviruses also recognize matching sites on SARS-CoV-2, the virus that causes COVID-19.
- Having a strong T cell response, or a better T cell response may give you the opportunity to mount a much quicker and stronger response.
- 40%-60% of people never exposed to SARS-CoV-2 had T cells that reacted to the virus showing that their immune systems recognized the virus.
- This finding turned out to be a global phenomenon and was reported in people from the Netherlands, Germany, the United Kingdom and Singapore.
- This discovery suggests that fighting off a common cold coronavirus can induce cross-reactive T cell memory against SARS-CoV-2.
- Article based on experience working as a doctor in the emergency room of one of the big hospitals in Stockholm, Sweden, and of living as a citizen in Sweden.
- Unlike other countries, Sweden never went in to complete lockdown. Non-essential businesses have remained open, people have continues to go to cafés and restaurants, children have remained in school, and very few people have bothered with face masks in public.
- COVID hit Stockholm like a storm in mid-March. One day I was seeing people with appendicitis and kidney stones, the usual things you see in the emergency room. The next day all those patients were gone and the only thing coming in to the hospital was COVID. Practically everyone who was tested had COVID, regardless of what the presenting symptom was. People came in with a nose bleed and they had COVID. They came in with stomach pain and they had COVID.
- Then, after a few months, all the COVID patients disappeared.
- At the peak three months back, a hundred people were dying a day of COVID in Sweden, a country with a population of ten million. We are now down to around five people dying per day in the whole country, and that number continues to drop. Since people generally die around three weeks after infection, that means virtually no-one is getting infected any more.
- The risk of dying is at the very most 1 in 200 if you actually do get infected.
- In total COVID has killed under 6,000 people in a country of ten million.
- Sweden has an annual death rate of around 100,000 people. Considering that 70% of those who have died of COVID are over 80 years old, quite a few of those 6,000 would have died this year anyway.
- COVID will never even come close to major pandemic numbers like 1918 flu.
- If herd immunity hasn’t developed, where are all the sick people? Why has the rate of infection dropped so precipitously?
- The reason we test for antibodies is because it is easy and cheap. Antibodies are in fact not the body’s main defence against virus infections. T-cells are. But T-cells are harder to measure than antibodies, so we don’t really do it clinically.
- Sweden ripped the metaphorical band-aid off quickly and got the epidemic over and done with in a short amount of time, while the rest of the world has chosen to try to peel the band-aid off slowly.
- I am willing to bet that the countries that have shut down completely will see rates spike when they open up. If that is the case, then there won’t have been any point in shutting down in the first place, because all those countries are going to end up with the same number of dead at the end of the day anyway. Shutting down completely in order to decrease the total number of deaths only makes sense if you are willing to stay shut down until a vaccine is available. That could take years.
- COVID has at present killed less than 6000 in Sweden. It is very unlikely that the number of dead will go above 7,000. An average influenza year in Sweden, 700 people die of influenza. Does that mean COVID is ten times worse than influenza? No, because influenza has been around for centuries while COVID is completely new.
- So it is quite possible, in fact likely, that the case fatality rate for COVID is the same as for influenza, or only slightly higher, and the entire difference we have seen is due to the complete lack of any immunity in the population at the start of this pandemic.

A randomized placebo-controlled trial in children showed that flu shots increased fivefold the risk of acute respiratory infections caused by a group of noninfluenza viruses, including coronaviruses. (Cowling et al, Clin Infect Dis 2012;54:1778) From Table 3, vaccine recipients had 20 noninfluenza virus-positive ARIs and 19 virus-negative ARIs; non-recipients had 3 noninfluenza virus-positive ARIs and 14 virus-negative ARIs. These figures yield an odds ratio of 4.91 (CI 1.04 to8.14).
Such an observation may seem counterintuitive, but it is possible that influenza vaccines alter our immune systems non-specifically to increase susceptibility to other infections; this has been observed with DTP and other vaccines. (Benn et al, Trends in Immunology, May 2013) There are other immune mechanisms that might also explain the observation.
“Intensive care units are getting empty, the wards are getting empty, we are really seeing a decrease — and that despite that people are really loosening up. The beaches are crowded, social distancing is not kept very well … but still the numbers are really decreasing. That means that something else is happening – we are actually getting closer to herd immunity. I can’t really see another reason.”
“I can’t say if the Swedish approach was right or wrong – I think we can say that in one or two years when we are looking back. You have to look at the mortality over the whole period.”
“I don’t think that we have more new cases, I think we are just detecting more cases”
“We found that if you have a mild case you can be negative for antibodies afterwards … in those almost all of them had strong T-cell activity. This study says that there are cases that you can have a strong T-cell response even though you have not had antibodies, meaning that you have encountered the virus and built up immunity.”
Such is the quality of decision-making in the process generating our lockdown narrative. An early maintained but exaggerated belief in the lethality of the virus reinforced by modelling that was almost data-free, then amplified by further modelling with no proven predictive value. All summed up by recommendations from a committee based on qualitative data that hasn’t even been peer-reviewed.
- According to Office for National Statistics, this year comes only eighth in terms of deaths in past 27 years.
- The spread of viruses like Covid-19 is not new. What’s new is our response.
- The whole Covid drama has really been a crisis of awareness of what viruses normally do, rather than a crisis caused by an abnormally lethal new bug.
- Modelling is not science, for the simple reason that a prediction made by a scientist (using a model or not) is just opinion.
- To be classified as science, a prediction or theory needs to be able to be tested, and potentially falsified.
- A problem with the current approach: a wilful determination to ignore the quality of the information being used to set Covid policy.
- Most Covid research was not peer- reviewed.
- In medical science there is a well-known classification of data quality known as ‘the hierarchy of evidence’: a seven-level system gives an idea of how much weight can be placed on any given study or recommendation.
- Randomised controlled trials (RCTs) form the highest, most reliable form of medical evidence: Level 1 and 2.
- Virtually all evidence pertaining to Covid-19 policy is found in the lowest levels (much less compelling Levels 5 and 6): descriptive-only studies looking for a pattern, without using controls.
- Level 7 is at the bottom of the hierarchy (the opinion of authorities or reports of expert committees) because ‘authorities’ often fail to change their minds in the face of new evidence.
- Committees often issue compromise recommendations that are scientifically non-valid.
- The advice of Sage (or any committee of scientists) is the least reliable form of evidence there is.
“[R]oughly twice as many people have developed T-cell immunity compared with those who we can detect antibodies in.“
SARS-CoV-2-specific memory T cells will likely prove critical for long-term immune protection against COVID-19. We systematically mapped the functional and phenotypic landscape of SARS-CoV-2-specific T cell responses in a large cohort of unexposed individuals as well as exposed family members and individuals with acute or convalescent COVID-19. Acute phase SARS-CoV-2-specific T cells displayed a highly activated cytotoxic phenotype that correlated with various clinical markers of disease severity, whereas convalescent phase SARS-CoV-2-specific T cells were polyfunctional and displayed a stem-like memory phenotype. Importantly, SARS-CoV-2-specific T cells were detectable in antibody-seronegative family members and individuals with a history of asymptomatic or mild COVID-19. Our collective dataset shows that SARS-CoV-2 elicits robust memory T cell responses akin to those observed in the context of successful vaccines, suggesting that natural exposure or infection may prevent recurrent episodes of severe COVID-19 also in seronegative individuals.
- We have already developed herd immunity to COVID-19 and will continue to manage it through herd immunity.
- Flu is much more dangerous than COVID-19.
- COVID-19 will settle into an endemic state just like flu.
- Hopefully vaccines will be important in protecting the vulnerable.
- Another way to protect the vulnerable sector is to allow the population to develop natural immunity.
- There’s no reason to think the virus will mutate into a lower level of virulence.
- During the 1918 flu because of a large number of ‘immunologically naive’ individuals but this is not the case with COVID-19.
- Most of us have some degree of coronavirus immunity and therefore some protection to COVID-19.
- The current H1 influenza strain is antigenically identical to the 1918 flu. H1 flu doesn’t kill as many people as the 1918 flu because most people already have cross immunity.

Sars-Cov-2 isn’t all that new, but merely a seasonal cold virus that mutated and disappears in summer, as all cold viri do — which is what we’re observing globally right now. Flu viri mutate significantly more, by the way, and nobody would ever claim that a new flu virus strain was completely novel.
In mid-April work was published by the group of Andreas Thiel at the Charité Berlin. A paper with 30 authors, amongst them the virologist Christian Drosten. It showed that in 34 % of people in Berlin who had never been in contact with the Sars-CoV-2 virus showed nonetheless T-cell immunity against it (T-cell immunity is a different kind of immune reaction, see below). This means that our T-cells, i.e. white blood cells, detect common structures appearing on Sars-CoV-2 and regular cold viri and therefore combat both of them.
…almost no children under ten years old got sick, everyone should have made the argument that children clearly have to be immune. For every other disease that doesn’t afflict a certain group of people, we would come to the conclusion that that group is immune. When people are sadly dying in a retirement home, but in the same place other pensioners with the same risk factors are left entirely unharmed, we should also conclude that they were presumably immune.
Epidemiologist also fell for the myth that there was no immunity in the population. They also didn’t want to believe that coronaviri were seasonal cold viri that would disappear in summer. Otherwise their curve models would have looked differently. When the initial worst case scenarios didn’t come true anywhere, some now still cling to models predicting a second wave.
The term “silent carriers” was conjured out of a hat and it was claimed that one could be sick without having symptoms.
The next joke that some virologists shared was the claim that those who were sick without symptoms could still spread the virus to other people…But for doctors and virologists to twist this into a story of “healthy” sick people, which stokes panic and was often given as a reason for stricter lockdown measures, just shows how bad the joke really is. At least the WHO didn’t accept the claim of asymptomatic infections and even challenges this claim on its website.
So if we do a PCR corona test on an immune person, it is not a virus that is detected, but a small shattered part of the viral genome. The test comes back positive for as long as there are tiny shattered parts of the virus left. Correct: Even if the infectious viri are long dead, a corona test can come back positive, because the PCR method multiplies even a tiny fraction of the viral genetic material enough [to be detected]…The crux was that the virus debris registered with the overly sensitive test and therefore came back as “positive”. It is likely that a large number of the daily reported infection numbers are purely due to viral debris.
If an infected person does not have enough antibodies, i.e. a weak immune response, the virus slowly spreads out across the entire body. Now that there are not enough antibodies, there is only the second, supporting leg of our immune response left: The T-cells beginn to attack the virus-infested cells all over the body. This can lead to an exaggerated immune response, basically to a massive slaughter; this is called a Cytokine Storm. Very rarely this can also happen in small children, in that case called Kawasaki Syndrome. This very rare occurrence in children was also used in our country to stoke panic. It’s interesting, however, that this syndrome is very easily cured. The [affected] children get antibodies from healthy blood donors, i.e. people who went through coronavirus colds.
The virus is gone for now. It will probably come back in winter, but it won’t be a second wave, but just a cold.
Those young and healthy people who currently walk around with a mask on their faces would be better off wearing a helmet instead, because the risk of something falling on their head is greater than that of getting a serious case of Covid-19.
People below 65 years old make up only 0.6 to 2.6 % of all fatal Covid cases. To get on top of the pandemic, we need a strategy merely concentrating on the protection of at-risk people over 65.
Antibody tests on random samples of the population have so far shown much lower levels of general infection than the government’s scientific advisers claimed would be necessary to attain ‘herd immunity’. In London, for example, tests have shown that 17 per cent of the population have antibodies to Sars-CoV-2, the virus that causes Covid-19. In New York, the figure is 21 per cent. At the beginning of this crisis, on the other hand, Sir Patrick Vallance, the chief scientific adviser, suggested that at least 60 per cent of the population would have to be infected in order to achieve herd immunity.
Straying away from a sedentary lifestyle is essential, especially in these troubled times of a global pandemic to reverse the ill effects associated with the health risks as mentioned earlier. In the view of anticipated effects on immune system and prevention against influenza and Covid-19, globally moderate to vigorous exercises are advocated wearing protective equipment such as facemasks. Though WHO supports facemasks only for Covid-19 patients, healthy “social exercisers” too exercise strenuously with customized facemasks or N95 which hypothesized to pose more significant health risks and tax various physiological systems especially pulmonary, circulatory and immune systems. Exercising with facemasks may reduce available Oxygen and increase air trapping preventing substantial carbon dioxide exchange. The hypercapnic hypoxia may potentially increase acidic environment, cardiac overload, anaerobic metabolism and renal overload, which may substantially aggravate the underlying pathology of established chronic diseases. Further contrary to the earlier thought, no evidence exists to claim the facemasks during exercise offer additional protection from the droplet transfer of the virus. Hence, we recommend social distancing is better than facemasks during exercise and optimal utilization rather than exploitation of facemasks during exercise.
The really concerning thing is that if all the deaths taking place during lockdown are put down as Covid-19 deaths, we are going to miss the fact that the lockdown policies have caused an increase in deaths from many other things. There has been a 50 per cent reduction in people turning up to A&E. It is clear that people just do not want to bother the doctors. And a number of these people will be dying. If we muddle the Covid-19 statistics in with the other statistics, we might think the lockdown has prevented a certain number of deaths, when it has actually caused a large number of deaths.
You hear this idea that all NHS staff have been working 20 times as hard as they have ever done. This is complete nonsense. An awful lot of people have been standing around wondering what the hell to do with themselves. A&E has never been so quiet.
The chances of children dying from COVID-19:
How many people aged 15 or under have died of Covid-19? Four. The chance of dying from a lightning strike is one in 700,000. The chance of dying of Covid-19 in that age group is one in 3.5million. And we locked them all down. Even among the 15- to 44-year-olds, the death rate is very low and the vast majority of deaths have been people who had significant underlying health conditions. We locked them down as well. We locked down the population that had virtually zero risk of getting any serious problems from the disease, and then spread it wildly among the highly vulnerable age group.
It is not clear that getting the virus actually makes you immune to it in the future, and it is not clear a vaccine would either.
Prolonged periods of lockdown cocooning the public from germs could leave people dangerously vulnerable to new viruses, a leading epidemiologist has warned.
Sunetra Gupta, professor of theoretical epidemiology at the University of Oxford, fears intense social distancing could actually weaken immune systems because people are not exposed to germs and so do not develop defences that could protect them against future pandemics.
Exposure to microbes during early childhood is associated with protection from immune-mediated diseases such as inflammatory bowel disease (IBD) and asthma. Here, we show that in germ-free (GF) mice, invariant natural killer T (iNKT) cells accumulate in the colonic lamina propria and lung, resulting in increased morbidity in models of IBD and allergic asthma as compared with that of specific pathogen-free mice. This was associated with increased intestinal and pulmonary expression of the chemokine ligand CXCL16, which was associated with increased mucosal iNKT cells. Colonization of neonatal—but not adult—GF mice with a conventional microbiota protected the animals from mucosal iNKT accumulation and related pathology. These results indicate that age-sensitive contact with commensal microbes is critical for establishing mucosal iNKT cell tolerance to later environmental exposures.
Parents are over-sterlising the environments of their children because they don’t understand why dirt is good for us, a germ expert says.
Professor Jack Gilbert said that exposure to microbes prevalent in the great outdoors will establish a stronger, more robust immune system in young people.
“Most parents think all germs are bad, that is not true. Most will just stimulate your immune system and make you stronger,” Prof Gilbert told The Independent.
…Prof Gilbert also claims that hand sanitizer is more damaging to a child’s health than soapy water. According to Prof Gilbert, children’s immune systems were more healthy and robust than they are today because of more relaxed attitudes to germs. He explains that more fermented foods which contain bacteria, enable children higher exposure to animals, plants and soil more often.
