Vaccination or natural immunity

COVID-19 vaccine mandates should not discriminate against natural immunity, The unnaturalistic fallacy

COVID-19 vaccine requirements, debate,

policies should have recognised proof of natural immunity,

sufficient basis for exemption to vaccination requirements.


Two implausible claims about natural immunity:

Natural immunity is superior to ‘artificial’ immunity

It is better to acquire immunity through natural infection

Naturalistic fallacy (many things are natural, but not good)

(A natural public health strategy, increased overall morbidity and mortality)

We lack clear and convincing scientific evidence that vaccine-induced immunity has a significantly higher protective effect than natural immunity.

Vaccine requirements represent a substantial infringement of individual liberty, and other significant costs

Can only be justified if they are necessary for achieving a proportionate public health benefit.

Without compelling evidence for the superiority of vaccine-induced immunity, it cannot be deemed necessary to require vaccination for those with natural immunity.

‘vaccine passports’ ‘health passes’

Rationale for vaccine mandates

Preventing healthcare systems becoming overwhelmed, (staff and patients)

Reducing community viral transmission

Acquired immunity naturally, potentially equivalent to vaccination immunity

This is the unnaturalistic fallacy as opposed to the naturalistic fallacy

Natural immunity and vaccine-induced immunity, evidence

Equivalency of Protection From Natural Immunity in COVID-19 Recovered Versus Fully Vaccinated Persons: A Systematic Review and Pooled Analysis

All of the included studies found at least statistical equivalence between the protection of full vaccination and natural immunity;

and, three studies found superiority of natural immunity.

NNT to prevent one annual case of infection in COVID-recovered patients 218

NNT COVID-naïve patients, 6.5

33.5-fold difference in benefit between the two populations

our review demonstrates that natural immunity in COVID-recovered individuals is, at least, equivalent to the protection afforded by complete vaccination of COVID-naïve populations

Vaccinations for recovered people, marginal on an absolute basis.

Omicron in adults aged 65 or over

minimal or no effect against mild disease with the Omicron variant from 20 weeks after the second dose of ChAdOx1-S or BNT162b2

data are beginning to emerge which suggest that the effect of the vaccines on transmission may diminish within a matter of months

Immunological memory to SARS-CoV-2 assessed for up to 8 months after infection
Immunological memory is the basis for durable protective immunity after infections or vaccinations.

Substantial immune memory is generated after COVID-19, involving,

memory B cells, antibodies, memory CD4+Tcells, memoryCD8+T cells.

Circulating antibody titers were not predictive of T cell memory.

Do not reflect the richness and durability of immune memory to SARS-CoV-2.

Reinfection Rates Among Patients Who Previously Tested Positive for Coronavirus Disease 2019: A Retrospective Cohort Study

N = 150,325 patients

8,845 (5.9%)

141,480 (94.1%)

Protection against reinfection, 81.8%

Protection against symptomatic reinfection, 84.5%

Risk of SARS-CoV-2 reinfection and COVID-19 hospitalisation in individuals with natural and hybrid immunity: a retrospective, total population cohort study in Sweden

Cohort one, 2,039,106

Cohort two, 962,318 one dose

Cohort three, 567,810 two doses

767 individuals with natural immunity needed to be vaccinated to prevent one reinfection

Protection against the Omicron Variant from Previous SARS-CoV-2 Infection

Protection from prior infection against severe outcomes from Omicron remained robust, 87.8%

Reinfection often occurs with negligible symptoms and high Ct values, indicating reduced epidemiologic significance

The case for natural immunity exemptions

Vaccine requirements have significant costs

Substantial infringement of individual liberty

There are non-trivial risks associated with vaccination

  1. They are going to start jabbing 5-month children and upwards, this is sick child abuse. What kind of people will allow this to happen to their very own children… brainwashed ones? ?

  2. I'm glad to see Dr.Campbell seems to be finally realising there may well be some ulterior motive to the push for vaccines. I personally don't think they was ever needed and the whole situation and numbers were inflated massively. I also believe we'd have been out of the "pandemic" within 8-12 months if we just let it ride as it were.

  3. The “natural “ immune system has the purpose of keeping us healthy. It has true and tested virus fighting/management mechanisms.

    Synthetic immunology must adapt to the immune system in order to be effective. It serves as a supplement to our pre-existing immune system, but also has the ability to destabilize it. That is why you have unnatural side-effects from these synthetic chemicals.

  4. Question to all: I am triple vaxxed.(last vax 11.21) just recovered from a covid infection in that last 2 weeks. DO I need to go ahead and get my 4th vaxxed or wait another 5 ro 6 mons, and then take the new Moderna vax against Omnicron? Appreciate any thoughts on this ?

  5. The claim that philosophical arguments are not evidence-based and that scientific arguments are is a dogmatic declaration that nothing counts as evidence except that form of evidence that scientific arguments must appeal to in order to be reputable as scientific arguments.

  6. After 2.4 months, and 3 Pfizer vaccines, I finally contracted BA 4/5 here in Canada. (Montreal but live in Toronto). Cold like symptoms and chapped lips, which I never experienced in the past. A little persistent cough, some brief bouts of Chest heaviness, and periodic runny nose. Otherwise, all is good. After my 3rd Vax, my body went weird and my joint tendons felt like they were drying out? Once I was mobile,/moving, the dull ache would subside. But when sitting in hi-tech gaming chair at home office, the dull ache would re-appear. This strange body occurrence went away about a month ago. So I'm concerned about obtaining future Vax? Especially when a close friend developed pericarditis after 3rd Vax and another died unexpectedly of heart failure, a few weeks after 3rd Vax? I'm sure there are valid medical explanations, but there are numerous question regarding these Vax's…?🤔🤔🤔

  7. People are eyes glassed over self interested don't rock their boat drones who will take and do anything just to be in their own mind comfortable. Doesn't matter if it's real or true.

  8. 1:43 can you clear up something please….is natural immunity AS GOOD AS the jabs? Asking as im barred from a household and I want to know exactly what threat I pose to vaccinated people. I think I know the answer..but I want it in black and white. Cheers
