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.  

Database Errors Fuel False Claims about HIV Cases in Military

Database Errors Fuel False Claims about HIV Cases in Military

The rate of new HIV infections in the military has been relatively unchanged since 2017. But social media posts falsely claim that the military has recorded a “500% increase in HIV since the COVID vaccine rollout.” A Defense Department spokesperson said errors in a military database sparked the inaccurate claim.

No Evidence Excess Deaths Linked to Vaccines, Contrary to Claims Online

No Evidence Excess Deaths Linked to Vaccines, Contrary to Claims Online

COVID-19 vaccines substantially reduce the risk of dying from COVID-19, and serious side effects are very rare. Excess deaths among working-age adults in 2021 and 2022 were due to COVID-19 and other factors, not vaccination. Faulty logic underlies claims that vaccines caused mass disability and economic harm.
