COVID-19 Vaccines Save Lives, Are Not More Lethal Than COVID-19

COVID-19 Vaccines Save Lives, Are Not More Lethal Than COVID-19

COVID-19 vaccination reduces the risk of death from COVID-19. Social media posts have misused survey data and adverse events reports to falsely claim that COVID-19 vaccines have killed more people than COVID-19. But serious adverse events resulting from vaccination, including deaths, are rare.

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.

Posts Push Unproven ‘Spike Protein Detoxification’ Regimen

Serious side effects after COVID-19 vaccination are rare, and there isn’t evidence people need to undergo a “spike protein detoxification” regimen after getting vaccinated, contrary to claims made online. Nor has such a regimen been shown to help people recover from long COVID, or long-term health problems after having COVID-19.

Video Falsely Claims 850 People Died of Myocarditis in Mexico

Video Falsely Claims 850 People Died of Myocarditis in Mexico

Cases of myocarditis have been reported following mRNA COVID-19 vaccination, but they are rare and usually mild. Yet, a viral video distorts news reports to falsely claim 850 people died in Monterrey, Mexico, in June due to myocarditis. The figure comes from a false report of heat-related deaths.

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.

Viral Video Repeats Bogus Claim About Vaccines and Visible Ailments

Viral Video Repeats Bogus Claim About Vaccines and Visible Ailments

A video repeating the claim that COVID-19 vaccines are responsible for the sudden onset of various visible ailments — such as fainting and facial paralysis — is making the rounds, again. But, just like the other, similar posts we’ve addressed, there’s no support for this one, either.

Posts Exaggerate Significance of Swiss Study on Heart Risk and COVID-19 Vaccination

A Swiss study found that after a COVID-19 booster, less than 3% of people briefly had a slightly elevated blood level of a protein that can be a marker of heart injury. No one in the study had any serious heart damage, and other experts say the findings are unlikely to be clinically significant. Viral posts, however, are spinning the results to falsely claim that the study shows the vaccine’s risks are “off the scale.”

RFK Jr.’s COVID-19 Deceptions

RFK Jr.’s COVID-19 Deceptions

Robert F. Kennedy Jr.’s battle against vaccines — and against the institutions that promote them — goes back to at least the mid-2000s, as we explain in the first article of this series. But the arrival of COVID-19 gave the environmental attorney fresh grounds to intensify his attacks and a timely platform to gain new followers and revenue.

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.
