CLAIM: COVID-19 vaccines that rely on messenger RNA technology will teach the body to attack itself, leading to autoimmune disease.
THE FACTS: There is no evidence that the so-called messenger RNA, or mRNA, vaccines made by Pfizer-BioNTech and Moderna cause autoimmune disease.
In a 12-minute video that has been viewed more than 350,000 times on Facebook, a nurse practitioner warns people against getting the COVID-19 vaccines based on mRNA technology, falsely claiming that it will teach the body to attack itself and lead to autoimmune disease.
Tamika Morrow, a registered nurse practitioner in Michigan who posted the video to Facebook Dec. 16, provides a faulty account of how the mRNA vaccines work.
“So you mean to tell me they want people to get a vaccine that has never been used on human beings before that will send messages to your body to produce the coronavirus spike protein in your body that may cause autoimmune conditions that will be lifelong all to prevent a virus that will last 2-3 weeks,” she says. “They are allowing this whole virus thing to take off the way it is with the intent of getting everybody this vaccine. Stay away from the vaccine.”
Experts say the claim is false and misrepresents how the mRNA vaccines work. The mRNA vaccines for COVID-19 contain a genetic code that trains the immune system to recognize the spike protein on the surface of the virus to generate an immune response and fight it.
Morrow goes on to claim in the video that scientists with Pfizer and Moderna who have researched the vaccines found that there is a possibility that the vaccines cause autoimmune disease. She presents no evidence of this in the video and autoimmune disease was not described as an adverse reaction in any of the findings for the two vaccines.
Autoimmune diseases, which include rheumatoid arthritis and lupus, occur when the immune system attacks itself and is unable to distinguish normal cells from foreign cells.
The Associated Press reached out to Morrow, who defended her claim and questioned how determinations could be made about whether the vaccines are safe since long-term complications would not yet be apparent. In an email, Morrow provided the AP with an article referring to a 2018 journal review on mRNA vaccines that listed autoimmunity among possible adverse reactions. The article was co-authored by Dr. Drew Weissman, who has studied mRNA for decades and participated in groundbreaking research on the molecule.
But when reached by the AP, Weissman said such concerns weren’t applicable with the COVID-19 vaccines because they use a new kind modified RNA. Modified mRNA vaccines have been given to people for five years now.
“There is no data that says an mRNA vaccine can cause an autoimmune disease,” he wrote in an email. “I have not seen or heard of a single report that mRNA vaccines cause autoimmunity.”
The U.S. Food and Drug Administration found no specific safety concerns or serious side effects before concluding the Pfizer and Moderna vaccines could be used on an emergency basis.
