Severe acute respiratory syndrome coronavirus 2 (SARS–CoV–2) has led to the coronavirus disease 2019 (COVID–19) pandemic, severely affecting public health and the global economy. Adaptive immunity plays a crucial role in fighting against SARS–CoV–2 infection and directly influences the clinical outcomes of patients. Clinical studies have indicated that patients with severe COVID–19 exhibit delayed and weak adaptive immune responses; however, the mechanism by which SARS–CoV–2 impedes adaptive immunity remains unclear. Here, by using an in vitro cell line, we report that the SARS–CoV–2 spike protein significantly inhibits DNA damage repair, which is required for effective V(D)J recombination in adaptive immunity. Mechanistically, we found that the spike protein localizes in the nucleus and inhibits DNA damage repair by impeding key DNA repair protein BRCA1 and 53BP1 recruitment to the damage site. Our findings reveal a potential molecular mechanism by which the spike protein might impede adaptive immunity and underscore the potential side effects of full-length spike-based vaccines.

Vaccine spike protein enters cell nuclei, suppresses DNA repair engine of the human body, will unleash explosion of cancer, immunodeficiency, autoimmune disorders and accelerated aging
(Natural News) This finding can only be described as a true “horror” in its implications. Stunning new research published in Viruses, part of the SARS-CoV-2 Host Cell Interactions edition of MDPI (Open Access Journals) reveals that vaccine spike proteins enter cell nuclei and wreak havoc on cells’ DNA repair mechanism, suppressing DNA repair by as much as 90%.
The research paper is entitled, “SARS–CoV–2 Spike Impairs DNA Damage Repair and Inhibits V(D)J Recombination In Vitro” and is authored by Hui Jiang and Ya-Fang Mei, at the Department of Molecular Biosciences, The Wenner–Gren Institute, Stockholm University, SE-10691 Stockholm, Sweden, and the Department of Clinical Microbiology, Virology, Umeå University, SE-90185 Umeå, Sweden, respectively.
In the conclusion of the paper, authors write, “We found that the spike protein markedly inhibited both BRCA1 and 53BP1 foci formation (Figure 3D–G). Together, these data show that the SARS–CoV–2 full–length spike protein inhibits DNA damage repair by hindering DNA repair protein recruitment.”
The DNA repair mechanism, known as NHEJ (Non-Homologous End Joining) is a kind of intracellular “emergency response” system that repairs double-stranded DNA breaks. Without the NHEJ mechanism, all advanced multi-cellular life would cease to exist. No human being, animal or plant can survive with the integrity of its genetic code being protected and constantly repaired through multiple mechanisms.
DNA damage can be caused by exposure to radiation, chemicals found in foods and personal care products, or even exposure to mammography equipment. Excessive sunlight exposure can also cause DNA breaks, and minor DNA mutations occur spontaneously in all living organisms. Airline pilots, for example, are routinely exposed to ionizing radiation due to flying at altitude.
