What the Science Really Says About Natural Immunity vs. Vaccine Immunity, Strategies for Dealing with Ongoing Variants, and the Latest Research on the Risk of Breakthrough Infections in Cancer Patients

When it comes to the question of vaccine immunity verses natural immunity, the stance taken by the CDC is that vaccine immunity is stronger, which they maintain is confirmed by research. But when you analyze the study they use and compare it to, for example, the Israeli study that states the opposite, there is an enormous discrepancy. And this discrepancy is between studies that are designed to answer the same question.

The Israeli study[1] found that the vaccinated have a 27 times higher risk of symptomatic infection than those who recovered from Covid-19 infection. At the same time, the vaccinated were nine times more likely to be hospitalized for Covid. In contrast, a CDC study[2] by Bozio et al. claims that the Covid recovered are five times more likely to be hospitalized for Covid than the vaccinated. Both studies cannot be right. 

While a recent Centers for Disease Control and Prevention (CDC) report released findings that alleged recovered individuals have a 5.5 times more likely chance of being hospitalized when compared to vaccinated people with no prior infection, no other independent research corroborates these findings.

This CDC report was recently dismantled by Harvard epidemiologist Dr. Martin Kulldorf and was revealed to have fatal flaws.[3]  He states that the Israeli study was a “straightforward and well-conducted epidemiological cohort study that is easy to understand and interpret.” At the same time, he found the US study filled with flaws, deeming it fatally flawed. He goes on to say, “It is surprising that the CDC chose this case-control design rather than the less biased cohort design selected by the Israeli authors. Such an analysis would answer the question of interest and may have given a different result more in line with the Israeli study.”

A very recent December 4th, 2021, study[4] supported the finding of the Israeli study, in that infected individuals with or without one vaccination dose have better protection than uninfected doubly-vaccinated individuals 3 to 8 months after the last immunity-conferring event. The data from this study does not suggests that vaccinated individuals were more protected than previously infected individuals 3 to 6 months after the immunity-conferring event. This study highlights that hybrid immunity is the strongest immunity.  In other words, those that have been both infected and have received at least one dose of the vaccine.

How the Omicron Variant Differs

Other variants including Alpha, Beta, Gamma, and Delta have had maybe eight or 10 mutations in the spike protein, and that’s largely what’s given them their advantageous phenotype. Omicron originated with 30 or more mutations in the spike protein!

There has been rapid spread in South Africa’s Gauteng province of Omicron as it rapidly replaces Delta. Omicron is spreading almost three times faster when compared to the Delta variant, which was two times faster compared to previous variants.

Early Lab Data Provide Glimpse into Omicron’s Immune Escape

Preliminary data from a small study at a prominent South African lab have found a 41-fold reduction in neutralizing antibody titers for the Pfizer vaccine against Omicron.

Virologist Florian Krammer, PhD, of Mount Sinai hospital in New York City, noted that the drop was significant and raised concerns.[5]

Omicron was first identified on 23 November in South Africa by researchers using genome sequencing to investigate a puzzling surge in case numbers there. Daily cases went from 274 on 11 November to 1000 a fortnight later, and currently number more than 2000.

Stéphane Bancel, chief executive of Covid-19 vaccine maker Moderna, has predicted that omicron will cut the efficacy of existing vaccines. The new variant is also expected to be more resistant to antibody treatments such as those developed by Regeneron. “That is really a cause for concern,” says Barclay.[6]

Most experts now propose Omicron most likely developed in a chronically infected Covid-19 patient, likely someone whose immune response was impaired by another illness or a drug. When Alpha was first discovered in late 2020, that variant also appeared to have acquired numerous mutations all at once, leading researchers to postulate a chronic infection. The idea is bolstered by sequencing of SARS-CoV-2 samples from some chronically infected patients.[7]

Cancer Patients May Have Double the Risk of Breakthrough Infection After Covid-19 Vaccination

Most patients with solid tumors develop antibodies after Covid-19 vaccination, but many patients with hematologic malignancies fail to seroconvert, according to a meta-analysis published in the European Journal of Cancer.[8] Studies have shown that a “substantial proportion” of blood cancer patients who did not produce anti-S antibodies following complete vaccination continue to be seronegative after receiving an additional dose.[9]

The fact that some patients have poor immune responses even after 3 vaccine doses highlights the importance of additional precautions to prevent SARS-CoV-2 infection, according to Dr Vaca- Cartagena.[10]  However, it does appear for the time being that vaccine boosters provide protection to cancer patients. The meta-analysis did not include data on seroconversion rates in cancer patients after a booster dose of a Covid-19 vaccine.[11] Since the researchers conducted the meta-analysis, studies have come out suggesting that additional vaccine doses may benefit patients with cancer.[12],[13]

Viral resistance can drive enhanced infectiousness of SARS-CoV-2, which in turn may ultimately enable SARS-CoV-2 to utilize alternative cell surface determinants to enter permissive cells. It is plausible that mass vaccination may drive the virus to fully exploit its evolutionary capacity, including its ability to use alternate receptor domains other than the Spike protein. This can lead to enhanced pathogenicity.[14] This is not an anti-vax statement, but rather an insight into the importance of supporting our innate healing capacity.

Viruses continually mutate, and by relying solely on vaccines, we are engaging in a never-ending race to stay ahead of the mutations. Supporting our overall health and innate immune response capacity is not variant specific and is a prudent approach to Covid-19, particularly as it becomes more apparent that there will never be a “post-Covid” world. We need to understand and accept that Covid-19 is here to stay. We need strategies beyond vaccines alone for living with this virus, starting with building our own robust health and immunity and reducing known risk factors where possible.

There are volumes of existing irrefutable evidence that foods, herbs and specific nutrients possess potential antiviral immune enhancing ability against SARS-CoV-2. According to recent research, herbal medicines, like herbs and essential oils, may have a part to play in counteracting Covid-19.[15] As we head into the 3rd year of living with Covid-19, there is no doubt in my mind we would be in a very different situation today if we had embraced dietary, herbal, and nutritional medicine for supportive care during the past two years, but it’s not too late to start. In my next blog, I’ll be sharing all the wonderful antiviral properties of some of my favorite essential oils.

Updates on Ivermectin, Transmission, Natural Immunity and Herbal Medicine

The Covid-19 pandemic has now been with us for close to two years and shows no signs of ever being completely extinguished. Many epidemiologists believe that the virus is here to stay, in the same way that the seasonal flu and common cold are also part of our lives. My belief is that continuing attempts to eradicate the virus through vaccination are not the best way to deal with an ever-changing target. Viruses continually mutate, and I believe our best approach to staying healthy is to bolster our innate immunity, and when necessary, to employ treatments with minimal side effects.

Recent Paper on Ivermectin Ignores Positive Studies

I believe that Ivermectin has been maligned and misunderstood as a prophylactic and treatment for Covid-19. On October 29th 2021, Medscape published a paper titled “Re-Analysis, Ivermectin Benefits Disappeared as Trial Quality Increased.

This what the paper reports:

For the re-analysis, Andrew Hill, PhD, of the University of Liverpool in England, and colleagues included 12 studies with 2,628 participants, and assessed them for bias. Overall, four studies had a low risk for bias, four studies had moderate risk, three studies were at high risk for bias, and one was potentially fraudulent.

Taken at face value, the overall meta-analysis found a 51% increase in survival with ivermectin (P=0.01), but excluding the potentially fraudulent trial, ivermectin’s benefit fell to 38% and was of borderline significance (P=0.05), they reported.

Taking out the studies with a high risk of bias led to a further drop — down to a nonsignificant 10% increase in survival (P=0.66), they noted. Further removing studies with a moderate risk of bias took the benefit down to 4% (P=0.9).”[1],[2]

The bottom line is that they took 4 studies out of a total of 12, where ivermectin had the least impact, and said they were the ones without bias. Yet they give no details as to how they came to this conclusion. They also added two studies on remdesivir, with a total of 6 studies that actually referred to ivermectin, and again ignored the now close to 100 studies on ivermectin and Covid. 

My two recent papers, “Ivermectin and COVID-19 – Revision”[3] and “Ivermectin as a Prophylactic and Treatment for COVID-19”[4] highlight almost 40 studies, all of which show benefit. Why were none of these studies included?

Vaccines Have Little Effect against Delta Variant Transmission

Based on six new studies, people that are vaccinated appear to shed and spread Covid-19 Delta as much, or possibly even more, than the unvaccinated. 

Study 1: This study found comparable viral loads among vaccinated vs. non-vaccinated healthcare workers (HCWs) infected by variant Delta B.1.1.7, suggesting suboptimal protection of SARS-CoV-2 vaccines against new variants as compared to wild-type SARS-CoV-2.

Among all 55 PCR-positive HCWs, 24 (44%) had received at least one dose of the BNT162b2 vaccine, and 21 were fully vaccinated (diagnosed with COVID- 19>2 weeks after the second dose). The three individuals that had one dose had received it 11, 20 and 22 days before the positive PCR result. In 23 of 24 positive HCW, PCR showed the SARS-CoV-2 B.1.1.7 variant, in one single subject the B.1.177 variant. Up till May 12, only 2 HCWs required hospitalization, both of which were not vaccinated. Vaccinated (with at least one dose) HCWs did not differ significantly compared to non-vaccinated HCWs in regard to age, gender and epidemiological exposures.[5]

Study 2: This recent study (D. W. Eyre et al. preprint at medRxiv; 2021)[6] looked directly at how well vaccines prevent the spread of the Delta variant of SARS-CoV-2.  It showed that people infected with Delta are less likely to pass on the virus if they have already had a COVID-19 vaccine than if they haven’t.  However the protective effect of the vaccine is small, and dwindles alarmingly over time.

In this study, researchers analyzed testing data from 139,164 close contacts of 95,716 people infected with SARS-CoV-2 between January and August 2021 in the United Kingdom, when the Alpha and Delta variants were competing for dominance. Although vaccines did offer some protection against infection and transmission, Delta dampened that effect. A vaccinated person who had a ‘breakthrough’ Delta infection was almost twice as likely to pass on the virus as was someone who was infected with Alpha. And the vaccines effect on Delta transmission waned to almost negligible levels over time.

The results “possibly explain why we’ve seen so much onward transmission of Delta despite widespread vaccination,” says co-author David Eyre, an epidemiologist at the University of Oxford, UK.[7]

Study 3: Data released August 6th, 2021, by the CDC showed that vaccinated people infected with the Delta variant can carry detectable viral loads similar to those of people who are unvaccinated. The study stated, “Among five COVID-19 patients who were hospitalized, four were fully vaccinated; no deaths were reported. Real-time reverse transcription-polymerase chain reaction (RT-PCR) cycle threshold (Ct) values in specimens from 127 vaccinated persons with breakthrough cases were similar to those from 84 persons who were unvaccinated, not fully vaccinated, or whose vaccination status was unknown (median = 22.77 and 21.54, respectively).”[8]

Study 4: Ireland’s Waterford city district has emerged as the place with the highest rate of Covid-19 infection, despite the fact that it has the highest rate of vaccination in the Republic. The city’s south electoral area has a 14-day incidence rate of 1,486 cases per 100,000 of the population, three times the national average which stands at 493 infections per 100,000 people. Waterford has 99.7 per cent of its adult population fully vaccinated.[9]

Study 5: Singapore, with 82% of its population of 5.7 million fully vaccinated, was once believed to have passed the threshold for herd immunity. But it’s now seeing a surge in Covid-19 cases. In the month of October, Singapore reported record high cases since late September, with more than 2,900 new infections on Oct. 1.

Prior to this wave, the highest single-day total was 1,426 reported in April 2020.[10]

Study 6: A new study, which appears in The Lancet Infectious Diseases Trusted Source,[11] has found that vaccination alone is not enough to stop the household transmission of the Delta variant.

What we have learned so far is thatthe peak viral load of the Delta virus does not differ between fully vaccinated and nonvaccinated individuals. Also, the elimination of the Delta strain of the virus takes place more quickly in vaccinated individuals.

Natural Immunity and Covid-19 Update

While a much-publicized CDC report concluded that mRNA vaccination provides stronger protection against COVID-19 hospitalization than prior infection, there were several study limitations, including that it was not a randomized controlled trial and that the follow-up period was short. The findings also don’t negate the robust protection from prior infection which many studies have now confirmed. In fact, in a recent CDC science report[12] that reviews the totality of evidence, agency staff found that infection-induced immunity is durable for at least 6 months.

“Researchers at the Cleveland Clinic Health System conducted a study of 52,238 employees with and without a history of COVID-19, with or without vaccination. They found that those who recovered from COVID-19 and were vaccinated had equally low rates of repeat infection when compared with those who recovered and were unvaccinated. The investigators concluded that those previously infected were unlikely to benefit from COVID-19 vaccination.[13] In another study looking at the duration of immunity among the COVID-19-recovered, researchers found that the immune response against SARS-CoV-2 was persistent and relatively stable for at least a year.”[14]

Multiple studies also show that people who have recovered from COVID-19 are at least equally protected compared to fully vaccinated COVID-naive people.[15] This recent meta-analysis included nine clinical studies, including three randomized controlled studies, four retrospective observational cohorts, one prospective observational cohort, and a case-control study.

A new study, published in the November 2021 issue of the prestigious Lancet Journal, highlights protective immunity after recovery from SARS-CoV-2 infection. According to the review, an overwhelming amount of research confirms those who have natural immunity are well protected. Several studies have found that people who recovered from COVID-19 and tested seropositive for anti-SARS-CoV-2 antibodies have low rates of SARS-CoV-2 reinfection. This study puts to rest the questions surrounding the strength and duration of such protection compared with that from vaccination.

Within this review paper, studies published in PubMed to September 28, 2021 were analyzed, including well-conducted biological studies showing protective immunity after infection. Furthermore, multiple epidemiological and clinical studies, including studies during the recent period of predominantly delta (B.1.617.2) variant transmission, found that the risk of repeat SARS-CoV-2 infection decreased by 80.5–100% among those who previously had COVID-19.

The reported studies were large and conducted throughout the world. Another laboratory-based study that analyzed the test results of 9,119 people with previous COVID-19 from December 1, 2019 to November 13, 2020 found that only 0.7% became reinfected.[16]

Here is a breakdown of the research studies they reviewed:

Biological studies

  • Dan et al (2021): About 95% of participants tested retained immune memory at about 6 months after having COVID-19; more than 90% of participants had CD4+ T-cell memory at 1 month and 6–8 months after having COVID-19.[17]
  • Wang et al (2021): Participants with a previous SARS-CoV-2 infection with an ancestral variant produce antibodies that cross-neutralize emerging variants of concern with high potency.[18]

Epidemiological studies

  • Hansen et al (2021): In a population-level observational study, people who previously had COVID-19 were around 80·5% protected against reinfection.[19]
  • Pilz et al (2021): In a retrospective observational study using national Austrian SARS-CoV-2 infection data, people who previously had COVID-19 were around 91% protected against reinfection.[20]
  • Sheehan et al (2021): In a retrospective cohort study in the USA, people who previously had COVID-19 were 81·8% protected against reinfection.[21]
  • Shrestha et al (2021): in a retrospective cohort study in the USA, people who previously had COVID-19 were 100% protected against reinfection.[22]
  • Gazit et al (2021): In a retrospective observational study in Israel, SARS-CoV-2-naive vaccinees had a 13.06-times increased risk for breakthrough infection with the delta (B.1.617.2) variant compared with those who previously had COVID-19; evidence of waning natural immunity was also shown.[23]
  • Kojima et al (2021): in a retrospective observational cohort of laboratory staff routinely screened for SARS-CoV-2, people who previously had COVID-19 were 100% protected against reinfection.[24]

Clinical studies:

  • Hall et al (2021): in a large, multicenter, prospective cohort study, having had COVID-19 previously was associated with an 84% decreased risk of infection.[25]
  • Letizia et al (2021): in a prospective cohort of US Marines, seropositive young adults were 82% protected against reinfection.[26]

Potential Treatment of COVID-19 with Traditional Chinese (Herbal) Medicine

Traditional Chinese medicine (TCM) has shown success in treating viral infectious pneumonia. It has also exhibited therapeutic effects against infectious diseases, such as SARS and COVID-19. On February 7, 2020, the National Health Commission of the People’s Republic of China and the National Administration of Traditional Chinese Medicine recommended the Qingfei Paidu decoction, the Huashi Baidu formula, the Xuanfei Baidu decoction, the Jinhua Qinggan granule, the Lianhua Qingwen capsule/granule, and Xuebijing.

The experimental antivirus effects are mainly characterized by the direct inhibition of virus replication. Regarding the immune system destruction, inflammatory cytokine storm, and lung damage caused by COVID-19, some classic TCM formulas and proprietary Chinese medicines may regulate the immune system, reduce inflammatory responses, and suppress lung fibrosis and injury. Xuebijing, for example, has been found to have clinical efficacy in the treatment of COVID-19 for the treatment of flu-like symptoms, asthma, inflammation, tonsillitis, and sore throat.

Based on clinical results, TCM formulas have been applied to treat COVID-19, and their effects have been remarkable. Experimental studies have focused on the potential antiviral effects of classical formulas. For example, the Huashi Baidu formula has been recommended by the National Health Commission of the People’s Republic of China for the treatment of COVID-19 patients with mild and severe symptoms. Cai et al. identified 223 active ingredients in Huashi Baidu formula that potentially interact with 84 COVID-19-related target genes, such as ACE2, estrogen receptor 1, adrenergic receptor α1, and histone deacetylase 1.[27]

One of the many advantages of TCM and herbal medicine lies not only in its regulation of immunity, but also in its holistic regulation of metabolism and the intestinal environment and broad protective effects as well on organ systems.[28]

Indonesia First to Greenlight Novavax COVID-19 Vaccine

JAKARTA, Indonesia (AP) — Biotechnology company Novavax said Monday that Indonesia has given the world’s first emergency use authorization for its COVID-19 vaccine, which uses a different technology than current shots. The vaccine is easier to store and transport than some other shots, which could allow it to play an important role in boosting supplies in poorer countries around the world.

Novavax said it has already filed for authorization of the vaccine in the United Kingdom, European Union, Canada, Australia, India, and the Philippines.[29]

Also keep in mind, some people are allergic to polyethylene glycol (PEG), an ingredient in the mRNA (Pfizer and Moderna) vaccines. There’s no polyethylene glycol (PEG) in Novavax

How the Novavax COVID-19 Vaccine Works

Unlike the mRNA and vector vaccines, this is a protein adjuvant (an adjuvant is an ingredient used to strengthen the immune response and in this case it a plant saponin extract, called Matrix M, from the Soapbark tree).

While other vaccines trick the body’s cells into creating parts of the virus that can trigger the immune system, the Novavax vaccine takes a different approach. It contains the spike protein, made from a moth and not the RNA messenger. 

Unlike mRNA vaccines that command your own cells to manufacture the antigens that trigger an immune response, the Novavax vaccine contains the antigens themselves.  The lab-grown nanoparticle spike protein mimics the natural spike protein on the surface of the coronavirus cannot cause disease.

How did they get the spike protein?

The Novavax method uses moth cells to make spike proteins: 

  1. Researchers select the desired genes that create certain SARS-CoV-2 antigens (spike protein). 
  2. Researchers put the genes into a baculovirus, an insect virus.
  3. The baculovirus infects moth cells and replicates inside them.
  4. These moth cells create lots of spike proteins.
  5. Researchers extract and purify the spike proteins.

The Novavax vaccine has no genetic material, only proteins.

When the vaccine is injected, the Matrix-M Soapbark extract stimulates the immune system to produce antibodies and T-cell immune responses.

This tried-and-true method of making a custom copy of a virus spike protein has been used to develop vaccines against HPV, hepatitis B and influenza.[30]

So, there you have it.

Arjuna (Terminalia arjuna): A Potent Ayurvedic Heart Tonic

The stem bark of the Arjuna tree has been valued for heart health since 500 BC. This beautiful and amazing tree is native to central India and lives on average over fifty years. Ayurvedic physicians commonly prescribe the powdered tree bark for alleviating angina, hypertension and other cardiovascular conditions. In research, the bark extract has been shown to have diuretic and hypotensive properties.[1]

I often use Arjuna in my clinical practice, and combine it with hawthorn leaf, flower, and berry (Crataegus oxycantha); olive leaf (Olea europea); coleus (Coleus forskohli); grape seed extract; green coffee bean; celery seed (Apium graveolens) and rauwolfia (Rauwolfia serpentina). All of these botanicals have been found to have therapeutic benefit in cardiovascular health, and in particular for maintaining healthy blood pressure, tonifying the heart, and improving its function.

Ivermectin as a Prophylactic and Treatment for COVID-19

Having effective therapeutics is going to be increasingly important when it comes to confronting Covid-19 and the evolution of new variants. First detected in Japan, the R1 variant is the newest strain of COVID-19 that contains “multiple spike protein mutations”, that could enable it to bypass the antibody protection present in those who are fully vaccinated. Despite the low number of infections, former Harvard Medical School professor William A. Haseltine believes the new mutations found in the R.1 variant could allow it to spread more easily. The professor said the five variations found in R.1 can lead to “increased resistance to antibodies,” in an article written in Forbes earlier this week.

Weighing the Risk-to-Benefit Ratio of COVID-19 Vaccines

Given the ongoing discord within the scientific community regarding the short-term and long-term efficacy and safety of the different types of anti-SARS-CoV-2 vaccines, their experimental nature, and the availability of other therapeutic approaches,[1] such information should be universal and should be provided to every potential vaccine recipient. The safety and tolerance of COVID-19 vaccines must be carefully considered and studied even when the benefits may outweigh the disadvantages.[2]

How can I make my own weighing scale?
