If the findings are confirmed, the implications for Covid policy will be profound Authors: BY UNHERD Thursday, 26 August 2021 A major study conducted by Israeli researchers into natural immunity has found that immunity acquired via infection from Covid-19 is superior to immunity from the Pfizer vaccine. Researchers at Maccabi Healthcare and Tel Aviv University compared the outcomes […]
Authors: Authored by ‘Sundance’ via TheConservativeTreehouse.com, Pfizer got full FDA approval yesterday. “The move would make it the first Covid vaccine to go from emergency use authorization to full FDA approval.” With that in mind, it is worth a reminder that both Pfizer and Moderna stopped the clinical trials the FDA was using in their review: […]
Authors: By Dr. Sanchari Sinha Dutta, Ph.D.Jun 8 2021 Scientists from the Cleveland Clinic, USA, have recently evaluated the effectiveness of coronavirus disease 2019 COVID-19) vaccination among individuals with or without a history of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The study findings reveal that individuals with previous SARS-CoV-2 infection do not get additional […]
Authors: Alberto Mantovani, M.D., and Mihai G. Netea, M.D. Innate immunity is mediated by different cell types and cell-associated or fluid-phase pattern-recognition molecules and plays a key role in tissue repair and resistance against pathogens.1 Exposure to selected vaccines, such as bacille Calmette–Guérin (BCG) or microbial components, can increase the baseline tone of innate immunity and trigger […]

O’Halloran, Rachel M. Presti & Ali H. Ellebedy Abstract Long-lived bone marrow plasma cells (BMPCs) are a persistent and essential source of protective antibodies1,2,3,4,5,6,7. Individuals who have recovered from COVID-19 have a substantially lower risk of reinfection with SARS-CoV-28,9,10. Nonetheless, […]

Authors: Alessandro Sette 1 2, Shane Crotty 3 4 Abstract T cell reactivity against SARS-CoV-2 was observed in unexposed people; however, the source and clinical relevance of the reactivity remains unknown. It is speculated that this reflects T cell memory to circulating ‘common cold’ coronaviruses. It will be important to define specificities of these T cells and assess their association […]
