Is Natural Immunity More Long-lasting and Effective Against New SARS-COV-2 Viral Mutations?

Go here https://www.t-detect.com/ to get a T-test to see if you already have immunity from a previous SARS-COV-2 infection, but it is only available in the US for now.  Also, https://www.aditxtscore.com/get-tested/ tests for immunity to the SARS-COV-2 virus in some US states:

  • Is there evidence of prior exposure to the SARS-CoV-2 virus or vaccine?
  • Is there evidence that a robust immune response developed?
  • Is there evidence this immune response can protect against COVID-19?

Vaccine 'passports' must give credit for natural immunity

IgG and IgG/IgM antibody serology testing.  People not presently experiencing signs or symptoms may undergo an IgG or IgG/IgM antibody serology test via blood draw. The FDA has authorized the intended use of these antibody tests as aids in identifying individuals with an adaptive immune response to SARS-CoV-2 (COVID-19), indicating recent or prior infection.

Previous Covid Prevents Delta Infection Better Than Pfizer Shot. August 27, 2021. People who recovered from a bout of Covid-19 during one of the earlier waves of the pandemic appear to have a lower risk of contracting the delta variant than those who got two doses of the vaccine from Pfizer Inc. and BioNTech SE.

Contracting and beating COVID provides better protection against delta variant than Pfizer shot, new research shows. August 27, 2021.

Having SARS-CoV-2 once confers much greater immunity than a vaccine—but no infection parties, please.   Aug. 26, 2021 Nussenzweig’s group has published data showing people who recover from a SARS-CoV-2 infection continue to develop increasing numbers and types of coronavirus-targeting antibodies for up to 1 year. By contrast, he says, twice-vaccinated people stop seeing increases “in the potency or breadth of the overall memory antibody compartment” a few months after their second dose.

Natural immunity is stronger than vaccination, study suggests. 26 August 2021. Their findings were stark: double-jabbed, previously uninfected people are 13 times as likely to get Covid compared with the naturally immune. Natural infection was also found to significantly reduce the risk of catching symptomatic disease and of being hospitalised with Covid ...

Comparing SARS-CoV-2 natural immunity to vaccine-induced immunity: reinfections versus breakthrough infections. August 25, 2021.  The Pfizer vaccinated have 7 times higher risk of symptomatic COVID and are at greater risk of COVID hospitalizations than someone with natural immunity.

evidence of waning natural immunity was demonstrated, though SARS-CoV-2 naïve vaccinees had a 5.96-fold (95% CI, 4.85 to 7.33) increased risk for breakthrough infection and a 7.13-fold (95% CI, 5.51 to 9.21) increased risk for symptomatic disease. SARS-CoV-2-naïve vaccinees were also at a greater risk for COVID-19-related-hospitalizations compared to those that were previously infected.

Conclusions This study demonstrated that natural immunity confers longer lasting and stronger protection against infection, symptomatic disease and hospitalization caused by the Delta variant of SARS-CoV-2, compared to the BNT162b2 two-dose vaccine-induced immunity.

Our CDC director and recent studies have shown that the vaccinated not only can become ill will COVID-19 in the setting of vaccine failure, but they can also carry the virus in very high viral loads in the early symptomatic phase and, in this context, can become individual super-spreaders. So indeed, we are in a crisis of the vaccinated, who are directionally have lower rates of COVID-19 illness but passing it to unvaccinated victims who develop the syndrome.   ...

Kids’ Nose Cells Are Primed to Fight Viruses, May Explain Milder COVID-19. August 18, 2021.

1.) The ACE 2 receptor that the virus uses to gain entry to the host cell, has limited (less) expression and presence in the nasal epithelium in young children (potentially in upper respiratory airways); this explain partly why children are less likely to be infected in the first place, or spread it to other children or adults, or even get severely ill; the apparatus is simply not there as reported by Patel and  Bunyavanich.         

2) When one is vaccinated or get infected naturally, this drives the formation, tissue distribution, and clonal evolution of B cells which is key to encoding humoral immune memory. There is research evidence by Yang published in Science (May 2021) that blood examined from children retrieved prior to COVID-19 pandemic have memory B cells that can bind to SARS-CoV-2, indicating the potent role of early childhood exposure to common cold coronaviruses (coronaviruses). It underscores the importance of early childhood B cell clonal expansions and cross-reactivity/cross-protection, in subsequent exposures and responses to novel pathogens e.g. SARS-COV-2. “Consistent with reported serology, pre-pandemic children had class-switched convergent clones to severe acute respiratory syndrome coronavirus 2 with weak cross-reactivity to other coronaviruses….these results highlight the prominence of early childhood B cell clonal expansions and cross-reactivity for future responses to novel pathogens”. These two points may help explain why children are not candidates for the COVID-vaccines and may (are) well immune and can be considered ‘vaccinated’. “Giving them a dangerous vaccine has virtually no benefit but significant downsides (like death)”.

3) We would also draw attention to the research in the Journal of Infection by Galow (April 2021) that examined household transmission rates in children and adults. They reported that there was “no transmission from an index-person < 18 years to a household contact < 18 years (0/7), but 26 transmissions from adult index-cases to household contacts < 18 years (26/71, SAR 0=37)”. These findings are in line with evidence that children are less at risk of developing severe illness courses, and also are far less susceptible and likely to spread and drive SARS-CoV-2 (references 1, 2, 3, 4).

Why Are Globalists And Governments So Desperate For 100% Vaccination Rates? Aug 01, 2021. ... Why are they so desperate for every single person in the world to get the mRNA jab? ... After all, the average (IFR) death rate of covid is a mere 0.26% of those infected (this is a stat that the media consistently and deliberately refuses to mention to the public). This means that 99.7% of the public is in NO danger from covid whether they are vaccinated or not.  ...Do the vaccines ensure better odds? Well, according to recent statistics from Massachusetts, not necessarily, as they report over 5100 infections and 80 deaths of fully vaccinated patients. The media keeps telling us that only the unvaccinated are dying, but this is a lie, like so many other lies they have been peddling when it comes to covid. So, what’s the point of taking an experimental vaccine if the death rate of the virus is so low and the jab doesn’t necessarily protect you anyway?   ... There is no point. The science and the stats do not support it. The vaccines can’t even be credited with the decline in infections and deaths this year; the numbers plunged in January – Only 5% of the population was vaccinated by February. The only explanation for this is that the population hit herd immunity many months ago. Remember when governments said that they needed 70% herd immunity or vaccination to stop the lockdowns and mandates? The goalposts have been moves several times and the government “science” changes monthly. Now they claim herd immunity doesn’t matter and demand 100% vaccination.   ...We must ask the question again – Why the relentless government push for total vaccine saturation? It’s not saving lives, and the mandates remain regardless, so why?    ... I can only posit theories based on the evidence at hand, but I think it’s clear to most of us that the vaccines are NOT about public health nor are they about saving lives. They are obviously about something else.   ...As numerous virology and vaccine experts have warned over the past year, there is a great risk of harmful health side effects when it comes to experimental mRNA technology. Even one of the creators of mRNA vaccines has suggested that there are dangers in rolling out these gene

India Delta Data Contradicts Dems’ COVID Fear/Control Campaign.  July 27, 2021. With India’s current vaccination rate of only about 6 percent, most diagnosed with Delta in that country have experienced cold-like symptoms.

"What we can conclude definitively is that strict mask-wearing (especially among health care workers) failed to stop the spread one bit," Horowitz wrote. "Yet now they have achieved herd immunity and burned out the virus with just 3% vaccination (now up to 6%) with roughly one-sixth the death rate of the U.S. and the U.K. and less than one-half that of Israel."

Dr. Sucharit Bhakdi: URGENT! Some good news, and some troubling news. July 8, 2021. Dr. Bhakdi explains clearly, based on new scientific evidence:

- Your immune system is your best defence against SARS-CoV-2, and indeed all coronaviruses.
- If you have been infected, even if you experienced no symptoms at all, you are immune to all variants.
- We have already reached herd immunity.
- There is no scientific reason to vaccinate against SARS-CoV-2. There is simply no benefit and the rollout must be stopped.

ICAN DEMANDS CALIFORNIA LIFT RESTRICTIONS ON INDIVIDUALS THAT HAVE RECOVERED FROM COVID-19. May 4, 2021. Recently, California has announced changes to its Blueprint for a Safer Economy.  These updates include additional “freedoms” afforded to those who have been vaccinated with no mention of those who have already had and recovered from COVID-19. ... Given that the immunity offered by having had COVID-19 is more efficacious and more robust than from the vaccine, ICAN explained to California that its policy of loosening restrictions for those that have been vaccinated for COVID-19, but not for those that have had COVID-19, is unscientific and illegal.  In contrast to having had COVID-19, there is noevidence to prove that the COVID-19 vaccines prevent infection or transmission.

Eminent doc: Media censored COVID-19 early treatment options that could have reduced fatalities by 85%. Dr. Peter McCullough also explained that given an 80% level of herd immunity, broad vaccination has ‘no scientific, clinical or safety rationale.’ Thu Apr 8, 2021 ... “People who develop COVID have complete and durable immunity. And (that’s) a very important principle: complete and durable. You can't beat natural immunity. You can't vaccinate on top of it and make it better. There's no scientific, clinical or safety rationale for ever vaccinating a COVID-recovered patient. There's no rationale for ever testing a COVID-recovered patient,” he continued... “My wife and I are COVID-recovered. Why do we go through the testing outside? There's absolutely no rationale (for such testing).” ... “There's plenty of COVID-recovered patients. Let them forgo the vaccine and let people who are clamoring for it get it. But at 80 percent herd immunity, in the vaccine trials fewer than one percent … in the placebo actually get COVID. Fewer than one percent. The vaccine is going to have a one percent public health impact. That's what the data says. It's not going to save us, we’re already 80 percent herd immune,” he said.

We actually have the data for a virus that swept through parts of the world seventeen years ago called SARS, and remember SARS CoV-2 is 80% similar to SARS, so I think that’s the best comparison that anyone can provide.

“The evidence is clear: These very clever cellular immunologists studied all the people they could get hold of who had survived SARS 17 years ago. They took a blood sample, and they tested whether they responded or not to the original SARS and they all did; they all had perfectly normal, robust T cell memory. They were actually also protected against SARS CoV-2, because they’re so similar; it’s cross immunity.

“So, I would say the best data that exists is that immunity should be robust for at least 17 years. I think it’s entirely possible that it is lifelong. The style of the responses of these people’s T cells were the same as if you’ve been vaccinated and then you come back years later to see if that immunity has been retained. So I think the evidence is really strong that the duration of immunity will be multiple years, and possibly lifelong.

How Broad is Covid Immunity?  March 2021

  How Worried Should We Be About the Variants? March 2021. by Dr Michael Yeadon, Scientific Board member of Panda, Expert in Allergy & Respiratory (A&R) Therapeutic/PhD in Biochemistry and Toxicology, Former Chief Scientific Officer at Pfizer A&R unit/CEO and Founder of Ziarco, 25 years experience in Drug Discovery/40 Full Papers/63 Abstracts/two Books/six Patents and Marc Girardot, Member of Panda, Senior Advisor in Biotech & Automotive/INSEAD MBA, Advisor to an anti-Cancer therapeutic vaccine company/Ex-Global Lead of Cisco’s IBSG Automotive, 30 years of experience in Industry, High Tech and Biotech/two Patents.  Snippets include:

To date, no robust scientific evidence proves that any of the variants identified are more transmissible or deadly than the original... Prior immunity gained from the original SARS-CoV-2 should work perfectly well against any new ‘mutant variant’, given the 99.7% sequence similarity.... mRNA vaccines currently used for vaccination – Pfizer-BioNTech or Moderna – present the immune system with a large repertoire of targets, if not quite as large as a natural immune response. This is even more true of more traditional vaccines – Russia’s Sputnik and China’s Sinovac – which present an even wider repertoire. ... Many seem to have benefited from a form of immunity even though they had never met the actual virus, nor been vaccinated. These have gained their immunity from past epidemics and make up the large contingent of asymptomatics. The Tübingen University Hospital near Stuttgart, Germany found as much as 81% of its samples were carrying pre-existing specific T cells. Most likely, past common cold coronaviruses have – in effect – played an immunisation role against SARS-CoV-2. The same immunological mechanism has been proven to exist for influenza also... Some are advocating the vaccination of people who have recovered from COVID-19. Natural immunisation being the ultimate form of vaccination, we see absolutely no scientific nor medical justification for such a procedure. Even past infections by other forms of common cold coronaviruses have been found to protect from SARS-CoV-2. Injecting a vaccine should never be considered a trivial event. The decision should be based on a well thought out risk-benefit analysis... The evidence above supports that immunity evasion – though a theoretical possibility – is very unlikely. Mutant variants, emerging overseas or domestically, are an inevitable biological reality once a virus is in the population. Closing international borders will not stop new mutations of the SARS-CoV-2 virus circulating in the population. It is a futile endeavour with no scientific basis ... Although vaccines could be helpful for patients with mildly deficient immune systems, they would most likely not save very old patients with advanced immune senescence. Thus overconfidence in vaccine effectiveness for the very old could be a major risk, and mitigation treatments and immune boosting strategies should instead be contemplated.

Amish community in Pennsylvania becomes first in US to achieve herd immunity after reopening churches led to 90% of households being infected with the virus last year March 2021

  • The Plain community in Lancaster County has become the 'first to achieve herd immunity,' according to a local administrator of a medical center in the area 
  • Allen Hoover of the Parochial Medical Center said that 90% of households became infected with virus when they resumed church services late last spring
  • As Hoover observed, faith in herd immunity prompted members of community to relax on key mitigation efforts such as masking and social distancing

As SARS-CoV-2 initially infects the upper respiratory tract, its first interactions with the immune system must occur predominantly at the respiratory mucosal surfaces, during both inductive and effector phases of the response. However, almost all studies of the immune response in COVID-19 have focused exclusively on serum antibodies and systemic cell-mediated immunity including innate responses.

Immune system’s T cells can mount attacks against many coronavirus targets — even on new variants, LJI says By La Jolla Institute for Immunology. January 2021. A new study led by scientists at the La Jolla Institute for Immunology suggests that T cells try to fight SARS-CoV-2, the coronavirus that causes COVID-19, by targeting a broad range of sites on the virus. By attacking the virus from many angles, the body has the tools to potentially recognize different SARS-CoV-2 variants.

Do some people have protection against the coronavirus? By Dr. Sanjay Gupta and Andrea Kane, CNN. August 2, 2020. Immunity is comprised of not just antibodies but various T cells -- cells that act as "memory" to foreign invaders.  The good news, when it comes to this coronavirus, is that people who have never had any exposure to this virus may actually have some T-cell reactivity. A study that looked at blood that was collected between 2015 and 2018, well before the first Covid-19 infection, found some people had T cells that reacted to the virus.

Johns Hopkins Doctor Thinks COVID Will Be Largely Gone By April, Half of U.S. Has Herd Immunity By Katherine Fung On 2/19/21

Prevalence of anti-SARS-CoV-2 antibodies among blood donors in Northern Cape, KwaZulu-Natal, Eastern Cape, and Free State provinces of South Africa in January 2021 Extrapolating from antibody testing on blood donors, the researchers found antibody levels of 63% in Eastern Cape province (EC), 46% in Free State (FS), 52% in KwaZulu Natal (ZN) and 32% in Northern Cape (NC). These figures were between 15 and 22 times higher than the percentage of the population that had tested positive for the virus to date.

... there is nothing unusual about a COVID-19 epidemic going into spontaneous decline, even with antibody prevalence much lower than in South Africa. Places with few restrictions such as Sweden, Florida and South Dakota have also seen spikes fall almost as quickly as they have risen, and at much lower antibody levels – and in the middle of winter, too.

According to an Office of National Statistics survey published today, more than half of people in England now have Covid antibodies. MailOnline has more.
