Vaccinated 27x More Likely To Be Symptomatically Infected Than Unvaccinated Who’ve Had COVID

A shocking new study from Israel compares the protection offered by vaccine-induced immunity versus natural immunity from a previous COVID-19 infection and finds the latter offers far more robust protection from infection, symptomatic disease, and hospitalization.

Natural immunity confers  much longer lasting protection

Directly comparing 16,215 previously COVID-19 infected individuals to 16,215 fully vaccinated individuals, 10 physicians  (Gazit et al., 2021) preliminarily report (pre-print) fully vaccinated people are (a) 13 times more likely to be infected with COVID-19, (b) 27 times more likely to be symptomatically infected, and (c) 8 times more likely to be hospitalized than unvaccinated people with a prior COVID infection (natural immunity).

“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.”

Other studies (Dan et al., 2021, Turner et al., 2021) have also indicated natural immunity obtained from a prior infection affords long-lasting, even “lifetime” anti-body protection from re-infection, or that “individuals who have had SARS-CoV-2 infection are unlikely to benefit from COVID-19 vaccination” (Shrestha et al., 2021).

Vaccine effectiveness declines 56% within just 70 days

A new study published in The Lancet reports an initial surge of antibody protection for those who have received the second dose of the Pfizer vaccine.

Unfortunately, within weeks after the last shot, vaccine effectiveness begins to dramatically decline. In just 2½ months, Pfizer vaccine antibody levels have plummeted by 56%.

An “exponential decrease” in vaccine effectiveness of up to 40% per month after last shot

Another new study highlights the precipitous drop in antibody protection almost immediately following getting jabbed for the second time.

While those with natural immunity from a prior COVID-19 infection (convalescents) lose <5% antibody protection per month after a COVID-19 infection, vaccinated-only individuals lose up to 40% of their immunity protection every month after their last shot.

At this pace, the artificial immunity afforded by vaccines wears off within a few months.

If strong and lasting protection from symptomatic disease, hospitalization, and death favors natural infection with COVID-19 over vaccination, then an understandable, “Catch-22” objection would be that it is still worse to be infected with COVID-19 than injected with the various immunizing vaccines available.

But here is a larger context worth considering.

Underestimating the prevalence of COVID-19 infections vastly overestimates the fatality rate

Throughout 2020 several studies emerged assessing the actual prevalence COVID-19 infections in communities from antibody tests rather than just relying upon the number of confirmed cases. Because up to 96% of individuals contracting COVID-19 may have no symptoms, it is quite common for those infected with COVID-19 to not even know it. Therefore the prevalence – or number of individuals who have actually had COVID – has been assessed to be substantially higher in communities than when only using the number of confirmed cases suggests.

In Santa Clara, California, for example, the prevalence of COVID was assessed to be ~53,000 cases when extrapolating the assessed number of people with COVID-19 antibodies (seroprevalence). Instead of ~53,000, the number of confirmed cases in Santa Clara at the time of the study was 948, which is “56-fold lower than the number of infections predicted by this study” (Bendavid et al., 2021).

Another study (Doi et al., 2021) suggested the prevalence was “396 to 858-fold more than confirmed cases with PCR testing.”

With a much higher prevalence comes a much lower number of deaths per infection, or infection fatality rate (IFR).

“In conclusion, our findings imply that ≈518,000 persons in Guilan Province may have been infected with SARS-COV-2 as of April 19, 2020, which is substantially higher than the 1,600 cumulative confirmed cases recorded. As of May 3, if we assume a 3-week lag from time of infection to death, 625 persons had died of confirmed COVID-19 in Guilan Province. This number would correspond to an infection-fatality rate of 0.12%[Shakiba et al., 2020].

The global infection fatality rate for COVID-19 is 0.23%

According to a highly-cited synthesis of 61 studies from 51 locations across the globe using antibody (seroprevalence) data (Ioannidis, 2021), the median infection fatality rate (IFR) for COVID-19 (without vaccine intervention) has been determined to be 0.23% for all ages, and 0.05% (1 in 2000) for individuals under 70 years old.

The IFR for seasonal to pandemic flu, 0.1% to 0.67%, is similar to COVID-19 IFR

COVID-19’s 0.23% infection fatality rate is in the middle of the range of IFR estimates for seasonal (~0.1%) to “pandemic” influenza (i.e., 0.67% for the 1957-’58 “Asian flu” pandemic).

Dr. Anthony Fauci and Dr. Robert Redfield, CDC Director (US), published a NEJM paper in late February, 2020, correctly predicting “the overall clinical consequences of Covid-19 may ultimately be more akin to those of a severe seasonal influenza (which has a case fatality rate of approximately 0.1%) or a pandemic influenza (similar to those in 1957 and 1968)”.

Studies: vaccines may actually be enhancing, not neutralizing, COVID variants and spread

Disturbing trends from across the globe, especially in highly-vaccinated countries like Israel, Iceland, and the UK, suggest new cases, hospitalizations, and deaths among the fully vaccinated have been rising dramatically since about mid-July. A “pandemic of the vaccinated” phenomenon has just recently (August) begun making its way into the United States.

Within the last week, two more studies (Liu et al., 2021, Yahi et al., 2021) suggest the more recent variants (Delta) are resisting vaccine neutralization. Worse, current vaccines may even enhance COVID’s Delta variant’s infectivity by spawning more resistant mutations.

“[T]he emergence of SARS-CoV-2 variants may tip the scales in favor of infection enhancement. Our structural and modeling data suggest that it might be indeed the case for Delta variants” [Yahi et al., 2021].

Furthermore, “boosters,” or third shots, may actually “boost enhancing anti-bodies” more than neutralizing antibodies (Liu et al., 2021).

In other words, vaccines may be worsening the current COVID surge.

“85-90% of the hospitalizations are in fully vaccinated people”

In late July Israeli Minister of Health data suggested the vaccines’ effectiveness had fallen from the advertised >90% to 39%. It may be even lower now.

Here are some recent headlines from across the globe documenting the burgeoning pandemic of the fully vaccinated.

The pandemic of the fully vaccinated has just recently begun permeating the USA

The percentage of new COVID cases and deaths represented by the fully vaccinated used to be in the low single digits in June and into July. But in the last few weeks in the USA’s most vaccinated states (Oregon, Vermont), 20-40% of new cases and deaths are fully vaccinated individuals.

Since February, 75% of COVID-19 deaths in England have been vaccinated

Because deaths are the most important metric in assessing pandemic trends, the data out of England may be most concerning.

    Pierre, thank you over and over again for being faithful to the truth and the scientific method. I read every day and have done so from the time of early WattsUpWithThat days when that was true for many more blogs. I hope you stay safe and healthy. Also thanks for the continued science on the “Global Warming” fraud.

    Great Job Pierre!

    I’ve been following this PhD Neurobiologist since Marc of 2020.

    Also, the “vaccine” is NOT “fully approved” yet. Don’t be fooled. They haven’t even started making the “fully approved” yet, so how it could be, makes no sense.

    2 FDA letters are at that link.

    1. Richard Greene

      After many millions of injections it’s obvious FDA approval does not matter to that many people.

      1. Yonason

        Least of all the pharmaceutical industry.

    VERY NICE, Kenneth!

    Some supplementary material on why variants are to be expected, but that they arise out of the vaccinated population, not the unvaccinated.

    Today’s podcast by a PhD Neurobiologist

    It should remain there until the next one replaces it. Hopefully he’s saving them to an archive for future reference .

    The notion of “breakthrough” cases is absolute nonsense. Vaccinated people are getting sick and dying from the SHOTS- but it’s being blamed on “COVID” instead to cover this up. A Pfizer whistle-blower makes it clear that adverse effects from the shots themselves match the symptoms of “COVID”:

    Australia has descended into tyranny:

      The first video, featuring Karen Kingston,
      a former Pfizer employee,
      was excellent, and worth watching.

      I normally have no patience for videos.
      The fact that I listened for over a half hour
      is a miracle. Highly recommended.

      ”Vaccinated people are getting sick and dying from the SHOTS- but it’s being blamed on “COVID” instead to cover this up.” – CK

      It’s both, CK.

      The “vaccines” are non-sterilizing, which is why they aren’t vaccines, and so do not prevent disease, though they may mitigate symptoms in some. The shots themselves also cause harm in many ways, at times equaling or exceeding that of the virus itself.

    Do the author know the propaganda he continues to post destroys some of the good information?

    “85-90% of the hospitalizations are in fully vaccinated people”

    If 99% of people are vaccinated that is quite a good number.


    Chuckle .. typical German thoroughness, it’s taken me over a year to gather this information. Thankyou thankyou.

  8. pochas94

    So according to the Sivan et al study, in the vaccinated group 238 people got COVID, and the previously infected unvaccinated group 16,215 + 19 = 16,234 got COVID. This is “Shocking?”

  9. Robert Folkerts

    New Zealand has quite recently begun jabbing with the Pfizer jab. The govt. Medsafe publishes weekly reports tallying up adverse reactions to the jab. In the three months to August 7 there are 22 deaths on these lists. That number is similar to the deaths in NZ attributed to/with covid since the pandemic began. The total adverse reactions is in the many thousands, those listed as serious in many hundreds, plus those who, as the data list states, ” sadly died”.
    No mention of this from govtor media. One could perhaps wonder why the silence?

    Pretty good tutorial on the immune system, according to people I’ve come to trust…

    A whole LOT more complicated, and reliable, than the result of an injected mRNA segment coding for an obsolete version of a fragment of a highly toxic protein trimer.

    Analogy time….

    Hi Kenneth,

    Excellent post as always. I have a question if you could help me with.

    I understand the Pfizer uses the mRNA technique which I believe but not sure is what this post relates to.

    However I understand that the Astrazeneca product does not use the mRNA technology. Happy to be corrected.

    Do we have any information on the Astrazeneca product’s technique and its impacts apart from the blood clots?

    Just would like to see if these reports are universal for all of the different products or is there some segregation of side effects.

    Thank you
