Social Media Posts Misrepresent FDA’s COVID-19 Vaccine Safety Research

Social Media Posts Misrepresent FDA’s COVID-19 Vaccine Safety Research

A vaccine safety surveillance study from the Food and Drug Administration has been misrepresented online. The paper did not establish a link between the Pfizer/BioNTech COVID-19 vaccine and blood clots, as some have claimed — and to date, other, more robust research has not identified such associations.

Blood Transfusion Doesn’t Transfer COVID-19 Vaccine

Blood Transfusion Doesn’t Transfer COVID-19 Vaccine

A blood transfusion from a vaccinated person doesn’t transfer the inoculation to an unvaccinated person. But high-profile purveyors of misinformation have been promoting the long-standing false claim that it does.

‘Died Suddenly’ Pushes Bogus Depopulation Theory

What appear to be ordinary postmortem blood clots are held up in a viral online video as supposed evidence that there’s a depopulation plot underway using COVID-19 vaccination to kill people. There’s no evidence for this theory. The hourlong video also repeats numerous falsehoods that have previously been debunked.

Posts Distort Misleading Analysis of COVID-19 Vaccine Safety Data

A rigorous vaccine safety monitoring system has shown that the COVID-19 vaccines are safe and only rarely have serious side effects. But an article shared on social media falsely says that CDC data show more than 18 million people “were injured so badly” by a Pfizer/BioNTech or Moderna COVID-19 vaccine “that they had to go to the hospital.”

Social Media Claims Misrepresent Boston U. Study of What Causes Severity of COVID-19 Strains

Social Media Claims Misrepresent Boston U. Study of What Causes Severity of COVID-19 Strains

To study the role of the spike protein in the severity of COVID-19 illnesses, researchers exposed 10 mice prone to develop severe disease to a hybrid version of the virus. Eight mice died. Social media posts say researchers created a dangerous new variant with an “80 PERCENT Kill Rate,” potentially leaving the false impression that this pertains to humans. Also, the hybrid virus used in the study had a lower mortality rate than the original virus had on mice.

Florida’s COVID-19 Vaccination Analysis Is Flawed, Experts Say

Florida’s COVID-19 Vaccination Analysis Is Flawed, Experts Say

The state of Florida recently announced that it was no longer recommending that younger males receive mRNA COVID-19 vaccines, based on an unpublished analysis that purportedly found an increased risk of cardiac-related death following vaccination. But experts who specialize in the unique method used in the analysis say it was not properly done — and even if it had been, the findings would not mean that individuals should not get vaccinated.

Vaccinated People Not More Susceptible to COVID-19 Than Unvaccinated

Vaccinated People Not More Susceptible to COVID-19 Than Unvaccinated

Q. Are vaccinated and boosted people more susceptible to infection or disease with the omicron variant than unvaccinated people?
A. No. Getting vaccinated increases your protection against COVID-19. Sometimes, certain raw data can suggest otherwise, but that information cannot be used to determine how well a vaccine works.

COVID-19 Is Caused by a Virus, Not Snake Venom

COVID-19 Is Caused by a Virus, Not Snake Venom

The COVID-19 pandemic was caused by a novel coronavirus, first isolated in January 2020. But a viral video has been spreading a conspiracy theory that the pandemic has actually been a plot to poison people with snake venom.
