"Israelis who were vaccinated were 6.72 times more likely to get infected after the shot than after natural infection". https://archive.is/RlwBc
"Researchers from Washington University in St. Louis also reported last month that 11 months after a mild infection immune cells were still capable of producing protective antibodies. The authors concluded that prior Covid infection induces a “robust” and “long-lived humoral immune response,” leading some scientists to suggest that natural immunity is probably lifelong." https://archive.is/DkgW2
"Researchers from the Cleveland Clinic also published a study recently of 1,359 people previously infected with Covid who were unvaccinated. None of the subjects subsequently became infected, leading the researchers to conclude that “individuals who have had SARS-CoV-2 infection are unlikely to benefit from COVID-19 vaccination.”" https://www.medrxiv.org/content/10.1101/2021.06.01.21258176v...
A recent study found that the current vaccines do next to nothing to help the body’s CD8 T-cells, which is the key to long-term immunity. https://www.cell.com/cell-reports-medicine/fulltext/S2666-37...
“A natural infection induces hundreds upon hundreds of antibodies against all proteins of the virus, including the envelope, the membrane, the nucleocapsid, and the spike. Dozens upon dozens of these antibodies neutralize the virus when encountered again. Additionally, because of the immune system exposure to these numerous proteins (epitomes), our T cells mount a robust memory, as well. Our T cells are the ‘marines’ of the immune system and the first line of defense against pathogens. T cell memory to those infected with SARSCOV1 is at 17 years and running still.” said Dr. Ryan Cole, a Mayo Clinic-trained pathologist who runs one of the largest independent laboratories in the US who has spent the past 16 months examining and culturing SARS-CoV-2 specimens. https://archive.is/o/4suZi/https://www.theblaze.com/op-ed/ho...
A national survey shows 68% of Indians have SARSCoV2 antibodies, compared to 25% in January and 1% last spring. Experts say this is why cases and deaths have plunged so fast since May, even though few Indians are fully vaccinated. https://www.theguardian.com/world/2021/jul/21/covid-19-antib...
Protection of previous SARS-CoV-2 infection is similar to that of BNT162b2 vaccine protection. https://www.medrxiv.org/content/10.1101/2021.04.20.21255670v...
