Health insurance data falsely shared as 'spike in vaccine-related cancer cases' in South Korea - Yahoo News

South Korea's government health insurance agency has rebuked Facebook posts falsely presenting data on cancer patients' insurance claims as an increase in cancer cases due to Covid-19 vaccines. There is no evidence that Covid-19 vaccines cause cancer. As of February 2023, South Korea had not yet published data on the number of new cancer cases since its vaccine rollout began in 2021.

"In 2022, the number of cancer cases tripled. I cannot think of any other explanation besides the Covid-19 vaccines," reads a Korean-language Facebook post shared on November 21.

The Facebook post shows a photo of a datasheet titled: "Massive spike in patients diagnosed with cancer after Covid vaccinations".

The datasheet is credited to South Korea's Health Insurance Review and Assessment Service (HIRA), a government agency responsible for reviewing and evaluating healthcare costs and services.

The document says there were between 1.2 million and 1.5 million new cancer cases every year between 2016 and 2021, but that this shot up to more than three million new cancer cases in 2022 -- the year after South Korea began its Covid-19 vaccine roll-out in February 2021.

It alleges Covid-19 vaccines are the "direct cause" of the purported rise in the number of cancer cases.

Around 88 percent of South Koreans had received at least two Covid-19 vaccine doses, as of February 9, 2023.
