❓WHAT HAPPENED: An epidemiologist’s assertion that COVID-19 vaccination amounts to one of the largest carcinogenic exposures in history went viral on social media.
👤WHO WAS INVOLVED: Master of Public Health Nicolas Hulscher, of the McCullough Foundation.
📍WHEN & WHERE: February 2026, on X (formerly Twitter).
💬KEY QUOTE: “HUNDREDS of studies now indicate COVID-19 ‘vaccines’ are one of the LARGEST carcinogenic exposures in history.” – Nicolas Hulscher
🎯IMPACT: Hulscher’s claims have sparked a significant online debate.
Nicolas Hulscher, an epidemiologist at the McCullough Foundation with a Master of Public Health (MPH) degree from the University of Michigan School of Public Health, went viral on X (formerly Twitter) in February with explosive allegations about COVID-19 mRNA vaccines. In a post quoting concerns about rising cancer cases among young people, Hulscher wrote: “HUNDREDS of studies now indicate COVID-19 ‘vaccines’ are one of the LARGEST carcinogenic exposures in history.”
He followed with a list of 20 alleged mechanisms by which the vaccines increase the risk of multiple major cancers, disrupt thousands of critical genes, integrate into human genomes, drive genome instability and chronic inflammation, suppress DNA repair, and reactivate dormant cancers, among other issues.
🚨HUNDREDS of studies now indicate COVID-19 “vaccines” are one of the LARGEST carcinogenic exposures in history.
They:
1. Increase your risk of 7 major cancers
2. Disrupt THOUSANDS of critical genes
3. Integrate into human genomes
4. Drive genome instability
5. Enable tumor… https://t.co/xP917R6Qem pic.twitter.com/uD9eB81jPq— Nicolas Hulscher, MPH (@NicHulscher) February 12, 2026
In a follow-up post, Hulscher declared “The evidence is now undeniable,” linking eight studies he described as proving increased cancer risks, genomic integration, transcriptomic dysregulation, and “turbo cancer” cases tied to the vaccines.
The McCullough Foundation is led by Dr. Peter McCullough, a renowned cardiologist who has previously warned against the Democrats and a left-leaning “biopharmaceutical complex” exploiting an outbreak of bird flu or some similar virus to declare another pandemic and undermine a Republican government.
