South Korea study does not show Covid vaccine causes cancer
Influencers claim that a study from South Korea shows that covid jabs cause cancer. That is not true.
In Autumn 2025 a paper in South Korea was published that excited many a vaccine sceptic online. The paper claimed that receiving a vaccination against Covid19 was linked to a 27% increase in cancer risk.
However, when you dig into the data there is no evidence that the vaccine caused the cancer. We spoke to Professor Justin Fendos to explain why we cannot take this type of statistical analysis at face value.
