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.

RSV Surge in Children Likely Caused by ‘Immunity Gap,’ Not COVID-19 Vaccine

Hospitals across the country are seeing a spike of respiratory syncytial virus infections among children.

It’s Not News, Nor ‘Scandalous,’ That Pfizer Trial Didn’t Test Transmission

The COVID-19 vaccine clinical trials were designed to study the vaccine’s safety and efficacy in preventing symptomatic disease, not transmission. But online publications now misleadingly present the fact that the Pfizer/BioNTech vaccine was not tested for transmission as a “shocking admission” and proof that the company and the government lied.

COVID-19 Vaccine Opponents Misrepresent CDC Webcast on Causes of Blood Clots

COVID-19 Vaccine Opponents Misrepresent CDC Webcast on Causes of Blood Clots

The Centers for Disease Control and Prevention hosted an online seminar about the treatment of blood clots, which is expected to grow as the U.S. population ages and the obesity rate increases. But some vaccine opponents misrepresented the webinar to falsely suggest that the projected rise in blood clots is related to the COVID-19 vaccines.

Video Makes Baseless Claim About Insurance Coverage of Vaccinated Frenchman

Video Makes Baseless Claim About Insurance Coverage of Vaccinated Frenchman

COVID-19 vaccines have been found to be safe and effective in trials and real-world conditions. Yet an online video baselessly claims a French life insurer refused to pay benefits for a man who died after receiving the vaccine because the insurer deemed it “a medical experiment.” It also falsely claims that the same has happened in the U.S.
