Excess Cancer Cases Among COVID Vaxxed in S. Korea
A population wide retrospective cohort analysis using data from the Korean National Health Insurance database between 2021and 2023 (n = 8.4 million) found that COVID vaxx recipients have significantly higher risks of six different types of cancers, 1 year post vaxx, compared to those who did not get vaxxed within the last year. This includes thyroid cancer: HR 1.351 (95% CI, 1.206–1.514), gastric cancer: HR 1.335 (95% CI, 1.130–1.576), colorectal cancer: HR 1.283 (95% CI, 1.122–1.468), lung cancer: HR 1.533 (95% CI, 1.254–1.874), breast cancer: HR 1.197 (95% CI, 1.069–1.340), and prostate cancer: HR 1.687 (95% CI, 1.348–2.111). COVID modRNA transfections are associated with higher risks for thyroid, colorectal, lung, and breast cancers while the adenoviral vector are associated with higher risks of thyroid, gastric, colorectal, lung, and prostate cancers. Vaxxed males were more likely to develop gastric and lung cancers while vaxxed females were more likely to develop thyroid and colorectal cancers.

As I noted in a prior answer last year, excess deaths in S.Korea rose dramatically over the same time frame peaking at over 24% in 2022. This is only one of several non-COVID-19 diseases that have been found to be elevated among vaxxed populations, particularly those who are immunocompromised.
