Mioch et al.: "SARS-CoV-2 antibodies persist up to 12 months after natural infection in healthy employees working in non-medical contact-intensive professions"; suggesting long-term 'natural immunity'

In this cohort, SARS-CoV-2 antibodies persisted for up to 1 year after initial seropositivity, suggesting long-term natural immunity; score another win for natural immunity

‘Objectives: This study aimed to evaluate dynamics of antibody levels after exposure to SARS-CoV-2 for 12 months in Dutch non-vaccinated hairdressers and hospitality staff.

Methods: In this prospective cohort study, blood samples were collected every 3 months for 1 year and analyzed using a qualitative total antibody enzyme-linked immunosorbent assay (ELISA) and a quantitative immunoglobulin (Ig)G antibody ELISA. Participants completed questionnaires, providing information on demographics, health, and work. Differences in antibody levels were evaluated using Mann-Whitney U and Wilcoxon signed-rank tests. Beta coefficients (β) and 95% confidence intervals (CIs) were calculated using linear regression.

Results: Ninety-five of 497 participants (19.1%) had ≥1 seropositive measurement before their last visit using the qualitative ELISA. Only 2.1% (2/95) seroreverted during follow-up. Of 95 participants, 82 (86.3%) tested IgG seropositive in the quantitative ELISA too. IgG antibody levels significantly decreased in the first months (P <0.01) but remained detectable for up to 12 months in all participants. Older age (β, 10-years increment: 24.6, 95% CI: 5.7-43.5) and higher body mass index (β, 5kg/m² increment: 40.0, 95% CI: 2.9-77.2) were significantly associated with a higher peak of antibody levels.

Conclusion:

In this cohort, SARS-CoV-2 antibodies persisted for up to 1 year after initial seropositivity, suggesting long-term natural immunity.’

Dear Readers,

I also embed this short piece on The Wellness Company and The UNITY Project.

First, The Wellness Company.

I am proud to announce a unique partnership with The Wellness Company and everyone who believes in medical freedom. My dear and esteemed colleagues Dr. Peter McCullough and Dr. Harvey Risch are also in partnership with The Wellness Company which provides telemedicine services for long-haul COVID, vaccine injury, and medical exemptions along with supplements and products that are fully aligned with our values. This support for The Wellness Company stems from the sub-optimal medical care and response that we experienced throughout the pandemic. It became apparent that there are many glaring gaps in our healthcare system and people were not properly treated. Thus, the pivot by us to support The Wellness Company. Take a stand against a broken healthcare delivery system with a membership in The Wellness Company, which directly funds our fight against medical tyranny. Click here The Wellness Company for more information. 

I also provide scientific support to The UNITY Project out of California. A magical organization for good. I support this tremendous initiative with some fine colleagues who have been warriors in the fight against all the wrongs in COVID. The UNITY Project aligns with my core values for it is very fierce in its fight to protect children from the danger of the largely safety untested COVID gene injection (The Unity Project Formed by Concerned Parents to Coordinate Opposition to California's K-12 COVID-19 Vaccination Mandate) (contact: info@theunityproject.org).
