From the Brownstone Institute: From the beginning of the March 2020 lockdowns for the SARS-CoV-2 virus, the subject of natural immunity (also called post-infection immunity) has been neglected. Once the vaccination became widely available, what began with near silence at the beginning turned nearly into a complete blackout of the topic.
Even now, there is an absence of open discussion, presumably in the interests of promoting universal vaccination and required documentation of such vaccination as a condition of participating in public life and even the jobs marketplace. Still, the science exists. Many studies exist. Their authors deserve credit, recognition, and to have their voices heard.
These studies demonstrate what was and is already known: natural immunity for a SARS-type virus is robust, long-lasting, and broadly effective even in the case of mutations, generally more so than vaccines. In fact, a major contribution of 20th-century science has been to expand upon and further elucidate this principle that has been known since the ancient world. Every expert presumably knew this long before the current debates. The effort to pretend otherwise is a scientific scandal of the highest order, especially because the continued neglect of the topic is affecting the rights and freedoms of billions of people.
People who have contracted the virus and recovered deserve recognition. For that matter, people who prefer an exposure risk to the virus in order to gain robust immunity deserve the freedom to make that choice. The realization that natural immunity – which pertains now to perhaps half of the US population and billions around the world – is effective in providing protection should have a dramatic effect on vaccine mandates.
Individuals whose livelihoods and liberties are being deprecated and deleted need access to the scientific literature as it pertains to this virus. They should send a link to this page far and wide. The scientists have not been silent; they just haven’t received the public attention they deserve. The preparation of this list was assisted by links provided by Paul Elias Alexander and Rational Ground’s own cheat sheet on natural immunity, which also includes links to popular articles on the topic.
1. One-year sustained cellular and humoral immunities of COVID-19 convalescents, by Jie Zhang, Hao Lin, Beiwei Ye, Min Zhao, Jianbo Zhan, et al. Clinical Infectious Diseases, October 5, 2021. “SARS-CoV-2-specific IgG antibodies, and also NAb can persist among over 95% COVID-19 convalescents from 6 months to 12 months after disease onset. At least 19/71 (26%) of COVID-19 convalescents (double positive in ELISA and MCLIA) had detectable circulating IgM antibody against SARS-CoV-2 at 12m post-disease onset. Notably, the percentages of convalescents with positive SARS-CoV-2-specific T-cell responses (at least one of the SARS-CoV-2 antigen S1, S2, M and N protein) were 71/76 (93%) and 67/73 (92%) at 6m and 12m, respectively. Furthermore, both antibody and T-cell memory levels of the convalescents were positively associated with their disease severity.”
2. Comparing SARS-CoV-2 natural immunity to vaccine-induced immunity: reinfections versus breakthrough infections, by Sivan Gazit, Roei Shlezinger, Galit Perez, Roni Lotan, Asaf Peretz, Amir Ben-Tov, Dani Cohen, Khitam Muhsen, Gabriel Chodick, Tal Patalon. MedRxiv, August 25, 2021. “Our analysis demonstrates that SARS-CoV-2-naïve vaccinees had a 13.06-fold 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 for a symptomatic disease as well…. This analysis demonstrated that natural immunity affords longer lasting and stronger protection against infection, symptomatic disease and hospitalization due to the Delta variant of SARS-CoV-2, compared to the BNT162b2 two-dose vaccine-induced immunity.”
3. Shedding of Infectious SARS-CoV-2 Despite Vaccination, by Kasen K. Riemersma, Brittany E. Grogan, Amanda Kita-Yarbro, Gunnar E. Jeppson, David H. O’Connor, Thomas C. Friedrich, Katarina M. Grande, MedRxiv, August 24, 2021. “The SARS-CoV-2 Delta variant might cause high viral loads, is highly transmissible, and contains mutations that confer partial immune escape. Outbreak investigations suggest that vaccinated persons can spread Delta. We compared RT-PCR cycle threshold (Ct) data from 699 swab specimens collected in Wisconsin 29 June through 31 July 2021 and tested with a qualitative assay by a single contract laboratory. Specimens came from residents of 36 counties, most in southern and southeastern Wisconsin, and 81% of cases were not associated with an outbreak. During this time, estimated prevalence of Delta variants in Wisconsin increased from 69% to over 95%. Vaccination status was determined via self-reporting and state immunization records.”
4. Necessity of COVID-19 vaccination in previously infected individuals, by Nabin K. Shrestha, Patrick C. Burke, Amy S. Nowacki, Paul Terpeluk, Steven M. Gordon, MedRxiv, June 5, 2021. “Individuals who have had SARS-CoV-2 infection are unlikely to benefit from COVID-19 vaccination, and vaccines can be safely prioritized to those who have not been infected before.”
5. Large-scale study of antibody titer decay following BNT162b2 mRNA vaccine or SARS-CoV-2 infection, by Ariel Israel, Yotam Shenhar, Ilan Green, Eugene Merzon, Avivit Golan-Cohen, Alejandro A Schäffer, Eytan Ruppin, Shlomo Vinker, Eli Magen. MedRxiv, August 22, 2021. “This study demonstrates individuals who received the Pfizer-BioNTech mRNA vaccine have different kinetics of antibody levels compared to patients who had been infected with the SARS-CoV-2 virus, with higher initial levels but a much faster exponential decrease in the first group.”
