The headline looks like something on a supermarket tabloid. Unfortunately, it’s not, and there’s a nontrivial possibility that it is accurate. From Mike Adams at naturalnews.com:

(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.”
