Texas Doctor Spreads False Claims About COVID-19 Vaccines

Texas Doctor Spreads False Claims About COVID-19 Vaccines

Federal officials authorized two mRNA vaccines for COVID-19 after they were determined to be safe and effective against symptomatic illness in clinical trials. But a Texas doctor, in a widely shared video, falsely claims the vaccines don’t provide protection and that they’re actually “experimental gene therapy.”

Instagram Post Misrepresents FDA Document About Monitoring Vaccine Safety

Instagram Post Misrepresents FDA Document About Monitoring Vaccine Safety

A Food and Drug Administration presentation on monitoring the safety of COVID-19 vaccines listed possible adverse events the agency might track. But an Instagram post misrepresents the document, falsely claiming it shows the vaccines are known to cause harmful side effects — including death.

Hagler’s Widow Refutes Rumors About How He Died

Hall of Fame boxer Marvelous Marvin Hagler “died on March 13 of natural causes,” according to a statement posted on his official website. In a Facebook post, his widow, Kay Hagler, wrote that his death was not the result of a COVID-19 vaccination.

RFK Jr. Video Pushes Known Vaccine Misrepresentations

RFK Jr. Video Pushes Known Vaccine Misrepresentations

A video stoking fears of the COVID-19 vaccines in the Black community is being promoted online. But the film repeats misrepresentations about vaccines, generally, and exploits historical cases of unethical medical conduct to suggest without evidence that COVID-19 vaccines are unsafe.

Video Targets Gates With Old Clip, Misleading Edit

Video Targets Gates With Old Clip, Misleading Edit

In a 2010 TED Talk focused on developing new technologies to drastically reduce carbon dioxide emissions, Bill Gates briefly mentioned reducing the rate of population growth. A conspiratorial video circulating on Facebook misleadingly edits Gates’ talk to suggest his “wish” was to depopulate the planet through vaccines.

How do we know vaccines are safe?

No vaccine or medical product is 100% safe, but the safety of vaccines is ensured via rigorous testing in clinical trials prior to authorization or approval, followed by continued safety monitoring once the vaccine is rolled out to the public to detect potential rare side effects. In addition, the Food and Drug Administration inspects vaccine production facilities and reviews manufacturing protocols to make sure vaccine doses are of high-quality and free of contaminants.

How safe are the COVID-19 vaccines?

More than half a billion doses of COVID-19 vaccines have now been administered in the U.S. and only a few, very rare, safety concerns have emerged. The vast majority of people experience only minor, temporary side effects such as pain at the injection site, fatigue, headache, or muscle pain — or no side effects at all. As the Centers for Disease Control and Prevention has said, these vaccines “have undergone and will continue to undergo the most intensive safety monitoring in U.S.

No Evidence Vaccines Impact Fertility

No Evidence Vaccines Impact Fertility

Q: Do the COVID-19 vaccines cause infertility?
A: There’s no evidence that approved vaccines cause fertility loss. Although clinical trials did not study the issue, loss of fertility has not been reported among thousands of trial participants nor confirmed as an adverse event among millions who have been vaccinated. 

How were safe and effective COVID-19 vaccines developed so rapidly?

The unprecedented speed of the COVID-19 vaccines was due to multiple factors.
Candidates for an mRNA vaccine — the technology used for the Pfizer/BioNTech and Moderna vaccines — can be quickly designed once scientists know the genetic sequence of the virus and which protein to target. Researchers already knew from past experience with SARS and MERS, which are other diseases caused by coronaviruses, that the spike protein the virus uses to enter cells was likely the right one.
