The Whoppers of 2023

The Whoppers of 2023

Claims from the president, a former president and other presidential hopefuls made the list.

Yale Preprint Recorded Patient Experiences, Did Not Demonstrate Vaccines Cause New Syndrome

Yale Preprint Recorded Patient Experiences, Did Not Demonstrate Vaccines Cause New Syndrome

A preprint on a Yale-based study described chronic symptoms self-reported after COVID-19 vaccination by 241 members of an online group. The paper, which has not been peer-reviewed, did not show how common these symptoms are in the general population, nor whether vaccinations caused them — limitations popular online posts did not make clear.

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 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.

Injection Protects Babies from RSV Hospitalization, Has Not Been Linked to Deaths

Injection Protects Babies from RSV Hospitalization, Has Not Been Linked to Deaths

Each year, respiratory syncytial virus hospitalizes 58,000 to 80,000 children under age 5 in the U.S. The Food and Drug Administration recently approved an antibody injection for babies to protect them during the RSV season. There isn’t evidence the shots have killed any babies, contrary to social media claims.

What RFK Jr. Gets Wrong About Autism

What RFK Jr. Gets Wrong About Autism

Robert F. Kennedy Jr. makes a variety of incorrect or misleading claims about vaccines, COVID-19 and other health-related topics. But his views on vaccines rose to prominence when he began to advance the thoroughly debunked idea that they cause autism.

False Claim About Cause of Autism Highlighted on Pennsylvania Senate Panel

False Claim About Cause of Autism Highlighted on Pennsylvania Senate Panel

Studies have found the rate of autism is the same in vaccinated and unvaccinated children. But the false claim that vaccines are associated with the disorder persists. A prominent spreader of COVID-19 misinformation wrongly told legislators in Pennsylvania that autism is virtually nonexistent among the unvaccinated, citing the Amish population.

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 Make False Claim About Cause of Gender Dysphoria

Posts Make False Claim About Cause of Gender Dysphoria

Recent research suggests that gender dysphoria is likely caused by a combination of factors, including hormone exposure before birth. But social media posts make the baseless claim that it could be caused by a vaccine containing DNA from an aborted fetus of the opposite sex. There is no scientific evidence for such a claim, experts said.

Cleveland Clinic Study Did Not Show Vaccines Increase COVID-19 Risk

Cleveland Clinic Study Did Not Show Vaccines Increase COVID-19 Risk

Numerous studies have found that additional COVID-19 shots are generally associated with extra protection against the coronavirus. Many people on social media, however, have shared a preliminary finding from a Cleveland Clinic study and misrepresented it as proving that getting more doses increases a person’s risk of infection.
