A new peer-reviewed case report from Kochi Medical School (Japan) has just revealed the presence of spike protein but not nucleocapsid protein expression in cancer cells strongly suggesting a potential link between modRNA vaccines and cancer progression/metastasis.

Authors suggest that 3 mechanisms worked in this case, out of which 1 is novel : genomic integration of vaccine-derived mRNA or contaminant DNA fragments in host cells; immune tolerance induction via spike-driven PD-L1 upregulation and Type I interferon suppression, impairing anti-tumor immunity; estrogen receptor modulation by spike protein, potentially accelerating cancer proliferation.

This study is very important because it adds another 2 ways through ways through modRNA injection can cause a cancer.

A comprehensive literature review by Mathilde Debord titled "COVID-19 mRNA vaccines can induce cancer in 17 distinct ways, according to over 100 peer-reviewed studies" was previously published in Le Point Critique. Drawing from over 100 peer-reviewed studies, it outlines 17 distinct biological mechanisms by which the injections may initiate, accelerate, or reactivate malignant processes.

It was most up-to-date collection of studies explaining carcinogenic processes initiated by modRNA/AVV platforms. Now it must be updated, it is 18 ways now.
