A study published in June documented how one form of colon cancer saw a sixfold increase in individuals vaccinated with the Covid injection. The researchers explained the link between the shot and the cancer.
“Microsatellite instable (deficient mismatch repair, dMMR) colon cancer is associated with hypermutability and immune infiltration-activation. COVID-19 vaccines stimulate immune-inflammation response,” the study said in the ‘Introduction’ section.
A medical doctor broke down the findings on social media.
“Pfizer vaccination conferred sixfold increased risk,” Dr. Peter McCullough said regarding the study’s findings.
The researchers discussed how the Covid injection affects the immune system in a way that is linked to the onset of this type of colon cancer.
“Immune infiltration in dMMR colon cancer may interact with COVID-19 vaccine-induced immune activation,” the study said in the ‘Conclusion’ section.
The researchers compared the vaccinated and non-vaccinated cancer patients.
“The study was a single-center case-control study. Patients diagnosed with colon cancer at least three months after the last COVID-19 vaccine (BNT162b2, CoronaVac) dose were included. Patients with dMMR and microsatellite stable (MSS) tumors were defined as cases and controls, respectively, between June 2021 and June 2023,” the study said in the ‘Methods’ section. “Baseline characteristics and vaccine status between case-control groups were compared as univariable and multivariable. Inflammation markers were compared between MSS+CoronaVac and dMMR+BNT162b2 groups.”
After analyzing the study, Dr. McCullough discussed its findings on his Substack.
