Data from 8,407,849 individuals between 2021 and 2023 were obtained from the Korean National Health Insurance database. The participants were categorized into two groups based on their COVID-19 vaccination status. The risks for overall cancer were assessed using multivariable Cox proportional hazards models, and data were expressed as hazard ratios (HRs) and 95% confidence intervals (CIs). The HRs of thyroid (HR, 1.351; 95% CI, 1.206–1.514), gastric (HR, 1.335; 95% CI, 1.130–1.576), colorectal (HR, 1.283; 95% CI, 1.122–1.468), lung (HR, 1.533; 95% CI, 1.254–1.874), breast (HR, 1.197; 95% CI, 1.069–1.340), and prostate (HR, 1.687; 95% CI, 1.348–2.111) cancers significantly increased at 1 year post-vaccination.
It's not any 1 covid vaxx, it's every one.
In terms of vaccine type, cDNA vaccines [ed: Astra-Zeneca, J&J] were associated with the increased risks of thyroid, gastric, colorectal, lung, and prostate cancers; mRNA vaccines [ed: Moderna, Pfizer] were linked to the increased risks of thyroid, colorectal, lung, and breast cancers; and heterologous vaccination [ed: "mix and match"] was related to the increased risks of thyroid and breast cancers.

Booster-Dose Analysis
Gastric cancer: HR 1.23 (p = 0.041) → 23% higher risk with boosters
Pancreatic cancer: HR 2.25 (p < 0.001) → 125% higher risk with boosters
Interpretation: Booster doses were associated with notably higher risks of gastric and pancreatic cancers. For pancreatic cancer, the risk more than doubled in boosted individuals.
