Posts Spread False Claim About Moderna Patent Application

Posts Spread False Claim About Moderna Patent Application

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.

COVID-19 Vaccines Have Not Been Shown to Alter DNA, Cause Cancer

COVID-19 Vaccines Have Not Been Shown to Alter DNA, Cause Cancer

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.

No Proven Health Risks from Aspartame, But Also No Proven Benefits

No Proven Health Risks from Aspartame, But Also No Proven Benefits

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.

COVID-19 Vaccines Have Not Been Shown to Cause ‘Turbo Cancer’

COVID-19 Vaccines Have Not Been Shown to Cause ‘Turbo Cancer’

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.

TikTok Video Mangles American Cancer Society Breast Cancer Estimates

TikTok Video Mangles American Cancer Society Breast Cancer Estimates

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.  

Posts on Social Media Misinterpret Biden’s Quote on Previous Cancer

Posts on Social Media Misinterpret Biden’s Quote on Previous Cancer

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. 

Trump Takes Undue Credit for Cancer Progress

Trump Takes Undue Credit for Cancer Progress

President Donald Trump boasted of the lowest cancer death rate on record, and implied that his administration was responsible for the achievement. While he’s right about the statistic, the improved death rate is the result of decades-long efforts on cancer prevention, detection and treatment.

Biden Exaggerates Science on Burn Pits and Brain Cancer

Biden Exaggerates Science on Burn Pits and Brain Cancer

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.

Unpacking Biden’s and Trump’s Big Cancer Promises

Unpacking Biden’s and Trump’s Big Cancer Promises

On the campaign trail, former Vice President Joe Biden and President Donald Trump have both claimed that a cure to cancer would soon become a reality — if they were elected in 2020. Experts, however, don’t share that degree of optimism.

Trump’s Faulty Wind Power Claims

During an April 2 speech to the National Republican Congressional Committee, President Donald Trump once again attacked wind power, falsely claiming that noise from turbines causes cancer and that turbines sink property values by 75 percent. Both claims are unsubstantiated.
