I’ve watched John Campbell review all things related to COVID-19 since the beginning of the pandemic. He has proven to be 100% unbiased and willing to represent the evidence as well as he understands it.

His first video on Coronavirus aired Jan 26, 2020. He now has 1.2M viewers on YouTube – with endless videos, one or two per day, he has covered nearly every aspect of COVID-19 and SARS-CoV-2.

In this video, he reviews the scientific evidence of natural immunity, which he says “seems good and long-lasting and cheap, lots of evidence below.”

He expansion collection of links and annotations are provided below for those looking for resources on evidence of natural immunity.

Dan et al (2021) Science, Immunological memory to SARS-CoV-2 assessed for up to 8 months after infection.

https://www.science.org/doi/full/10.1126/science.abf4063

95% of participants tested retained immune memory at about 6 months after having COVID-19

and 6–8 months after having COVID-19

Laboratory staff routinely screened for SARS-CoV-2, people who had had COVID-19 previously were 100% protected against reinfection

Previous COVID-19 diagnosis, 84% decreased risk of infection

Prospective cohort of US Marines.

Seropositive young adults were 82% protected against reinfection

https://academic.oup.com/cid/article/74/2/294/6251701

N = 9,119, serial tests

Reinfection rates, 0.7%

So

Risk of repeat SARS-CoV-2 infection decreased by 80·5–100% among those who had had COVID-19

Protection from reinfection is strong and persists for more than 10 months of follow-up, (Hansen et al 2021 Lancet)

Memory B-cell response to SARS-CoV-2 evolves between 1·3 and 6·2 months after infection, which is consistent with longer-term protection

Some people who have recovered from COVID-19 might not benefit from COVID-19 vaccination

One study found that previous COVID-19 was associated with increased adverse events following vaccination with Pfizer

In Switzerland, proof of recovered infection, in the past 12 months are considered equally protected as fully vaccinated,

Thank you, John!

**Comment**

I attempted to find a graphic of natural immunity but Google wouldn’t let me.  While not shocking, this is quite telling as natural immunity has been acknowledged from the beginning of time but is being downplayed, ignored, and frankly rewritten as only coming from “vaccines.”  This is intentional and you need to be aware of it.

This article explains how natural immunity to coronavirus lasts a year and perhaps a life-time, and that cells that retain a memory of the virus persist in the bone marrow and may churn out antibodies whenever needed. Natural immunity is long lasting, robust, and better than vaccines.  Further, effective treatments makes the need for a vaccine null and void, which of course is why they are ridiculing and attacking doctors who are educating others about these treatments.

• Recently a Johns Hopkins professors states to “ignore the CDC” due to their refusal to recognize natural immunity from previous infection. The WHO also recently changed the definition of herd immunity to now only come from vaccines, essentially rewriting hundreds of years of scientific understanding.
• There is ample evidence that those who have already had COVID should NOT get “vaccinated.” Dr. Hooman Noorchashm has repeatedly warned the FDA that “clear and present danger” exists for those who have had COVID-19 and subsequently get vaccinated due to viral antigens that remain in the body after a person is naturally infected; the immune response reactivated by the COVID-19 vaccine may trigger inflammation in tissues where the viral antigens exist. An international survey of 2,002 people found that people who had previously had COVID-19 experienced “significantly increased incidence and severity” of side effects after the COVID-19 vaccine
• It’s important to remember that COVID injections are part of a grand experiment where final data is unknown. These are experimental, fast-tracked injections that do not stop transmission or infection and have not undergone rigorous testing, have already proven to be the most dangerous injections in the history of VAERS.
