evidence: "!! TRUST THE #SCIENCE !!," the author of a viral post wrote on Instagram on Feb. 7. The post included a screenshot of a news story titled "Mainstream science mulls ‘global moratorium’ on COVID vaccines as cancers rise, boosters flub," and the statement "Covid vaccines *may* cause cancer. You don’t say." [...] The review also uncritically cites an unpublished analysis by former physics professor Denis Rancourt that alleged that some 17 million people died from the COVID-19 vaccines. We recently explained that the report erroneously ignored deaths from COVID-19 and that such estimates are implausible. And the review recycles unsupported claims about "high levels of DNA contamination" in the mRNA vaccines and the possibility that such DNA fragments "will integrate into the human genome" and cause cancer. As we’ve detailed, trace amounts of residual DNA are expected in vaccines, but there is no evidence the DNA can alter a person’s DNA or cause cancer.
