COVID-19: Natural Immunity 13X Stronger Protection and Lasts Longer than Vaccination

re: COVID-19
re: Long-Haul COVID
re: natural immunity
re: COVID-19: “vaccine passports are both UNSCIENTIFIC and discriminatory”

Real science is never settled, and anyone who has certainty on such things is not qualified to discuss it.

This study is from Israel. Israel is one the most vaccinated countries in the world and yet is seeing a major outbreak of the COVID Delta variant.

If this study proves-out with more studies*, those who have had COVID (natural immunity) can be assured that they are in a FAR better position than those who were only vaccinated. But note that similarly compelling findings were seen in the Cleveland Clinic Health System Study.

It is likely that narrative-undermining data on natural immunity will continue to pile up.

However, for some people there is still a risk of serious problems from COVID and/or Long-Haul COVID, so getting to natural immunity without serious issues is the trick. If not yet infected by COVID, you must make your own decision on vaccination vs infection based on your own personal circumstances.

You can bet that the mainstream propaganda outlets and government sources will never mention this study.

And when top Harvard epidemiologist Martin Kulldorff makes a point of citing it, you can have a high degree of confidence that it’s the real deal.

Harvard Epidemiologist Says the Case for COVID Vaccine Passports Was Just Demolished

Harvard Medical School professor Martin Kulldorff said research showing that natural immunity offers exponentially more protection than vaccines means vaccine passports are both unscientific and discriminatory, since they disproportionately affect working class individuals.

“Prior COVID disease (many working class) provides better immunity than vaccines (many professionals), so vaccine mandates are not only scientific nonsense, they are also discriminatory and unethical,” Kulldorff, a biostatistician and epidemiologist, observed on Twitter.

* There are confounders, but the results are so compelling that it seems highly unlikely to change the conclusions.

Comparing SARS-CoV-2 natural immunity to vaccine-induced immunity: reinfections versus breakthrough infections


Background: Reports of waning vaccine-induced immunity against COVID-19 have begun to surface. With that, the comparable long-term protection conferred by previous infection with SARS-CoV-2 remains unclear.

Methods: We conducted a retrospective observational study comparing three groups: (1)SARS- CoV-2-naïve individuals who received a two-dose regimen of the BioNTech/Pfizer mRNA BNT162b2 vaccine, (2)previously infected individuals who have not been vaccinated, and (3)previously infected and single dose vaccinated individuals...

Results: SARS-CoV-2-naïve vaccinees had a 13.06-fold (95% CI, 8.08 to 21.11) increased risk for breakthrough infection with the Delta variant compared to those previously infected, when the first event (infection or vaccination) occurred during January and February of 2021. The increased risk was significant (P<0.001) for symptomatic disease as well... 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. Individuals who were both previously infected with SARS-CoV-2 and given a single dose of the vaccine gained additional protection against the Delta variant.


WIND: the p-value of (p=0.001) is compelling, being 50 times better than the lax standard of =-0.05 so often used to claim statistical significance, and 10X better than a fairly rigorous p=0.01.

Meanwhile, the feckless aholes in charge are demanding (based on no science at all) that those with natural immunity get vaxxed, taking on all the risks of vaccination for little benefit:

Individuals who were previously infected with SARS-CoV-2 seem to gain additional protection from a subsequent single-dose vaccine regimen. Though this finding corresponds to previous reports24,25, we could not demonstrate significance in our cohort.

In other words, this science says that getting vaxed after infection carries risks, but with no proven benefit. It is unethical and anti-scientific to call for vaccination after infection.
