Connection Between Covid Vaccination
and Six Types of Cancer
A large-scale South Korean study on September 26, 2025, with data from over 8.4 million people, suggests that COVID-19 vaccination may be interconnected with an increased risk of six types of cancer. Among those evaluated, a so-called statistical link (which is not proof of causality) with increased risks of thyroid, stomach, colon, lung, breast and prostate cancer could be established in the first year after vaccination. According to the study published in the Journal “Biomarker Research”, the so-called “hazard ratios” (HR) for these types of cancer were significantly increased. This means that the risk of a cancer event occurring within the defined period was increased. The study also distinguishes between vaccine types (mRNA, cDNA, heterologous vaccination strategies) and shows that the correlations vary depending on the type of vaccine. The authors of the study emphasize that these are “epidemiological associations” and that the results are not evidence of a causal effect. However, they call for further research to identify possible mechanisms and influencing factors . (CS)
