The mRNA COVID-19 vaccines — like many other vaccines — can contain small amounts of DNA left over from the manufacturing process. There’s no evidence this residual DNA causes “turbo cancer,” or very aggressive cancer. Nor did Moderna admit that “mRNA Jabs Cause Turbo-Cancer,” contrary to an online article that misconstrues a line from a patent application.
Small amounts of DNA from the manufacturing process may remain in the mRNA COVID-19 vaccines. Purification and quality control steps ensure any leftover DNA is present within regulatory limits. There isn’t reason to think that this residual DNA would alter a person’s DNA or cause cancer, contrary to claims made online.
Some research indicates possible negative effects from aspartame, but there’s no definitive evidence linking it to health problems in the general population. Aspartame is safe when consumed within certain limits, according to the U.S. Food and Drug Administration. The daily limit is above the amount people typically ingest.
People with cancer are particularly vulnerable to severe disease and death from COVID-19. Vaccines provide needed protection. It has not been shown that COVID-19 vaccines cause or accelerate cancer. Nor does a recent paper about a mouse that died of lymphoma “prove” that the Pfizer/BioNTech vaccine induced “turbo cancer,” contrary to social media claims.
Breast cancer in younger women has been increasing gradually in recent decades. But a social media post misrepresents case number projections for 2022 and 2023 to falsely claim they show a dramatic rise in early-onset breast cancer — and then baselessly ties its faulty comparisons to COVID-19 vaccines.
President Joe Biden claimed in a July 20 speech that growing up in Delaware near oil refineries gave him cancer. Posts on social media misinterpreted that to mean he currently has cancer. A White House spokesperson said Biden was referring to a skin cancer that was removed before he became president.
Democratic presidential candidate and former Vice President Joe Biden claimed without evidence that “more people are coming home from Iraq with brain cancer” than “any other war,” and blamed burn pits for the purported increase. But existing statistics do not bear that out, and the evidence on the cancer risk of burn pits is inconclusive.
