Experts say mRNA COVID-19 vaccines have saved millions of lives, not caused mass deaths – PolitiFact

In the more than three years since COVID-19 vaccines first became available, billions of doses have been administered worldwide, protecting against severe disease and death. Still, social media posts claim the vaccines are causing more harm than good.

A Feb. 4 Instagram post shared a headline from conservative news outlet The Epoch Times that said, "mRNA COVID-19 vaccines caused more deaths than saved: study."

Another Instagram post shared a related headline that said, "Scientists call for global moratorium on mRNA vaccines, immediate removal from childhood schedule." The headline was from the Childrens Health Defense, a legal advocacy organization known for spreading vaccine misinformation. (The organization was created by Robert F. Kennedy Jr., who earned PolitiFacts 2023 Lie of the Year for his movement to legitimize conspiracy theories.)

The Epoch Times and Childrens Health Defense articles referred to a Jan. 24 research paper that said "for every life saved, there were nearly 14 times more deaths caused by" the mRNA COVID-19 vaccines. Two of the papers authors, Steve Kirsch and Peter McCullough, have often spread misinformation related to COVID-19 and the vaccine.

Experts on infectious diseases and vaccines told PolitiFact that the papers conclusion is based on misleading and false information about the mRNA COVID-19 vaccines. The paper repeats multiple claims that PolitiFact and other fact-checkers have debunked.

The paper "stands in contrast" to the global public health communitys consensus that the mRNA vaccines are safe and effective, said William Schaffner, a Vanderbilt University infectious diseases professor.

"And so, you have to ask why (the paper) is such an outlier," said Schaffner, who is also a spokesperson for the National Foundation for Infectious Diseases. "The reason its an outlier is its a deeply flawed study."

Papers claims about deaths

The peer-reviewed research paper was published on Cureus, which Schaffner called "an obscure journal" that hed never heard of in his 40 years of public health research. A 2022 Emory University study described Cureus as a "predatory" and "controversial" journal.

The paper claimed the Pfizer COVID-19 vaccine saved two lives and caused 27 deaths per 100,000 vaccinations. It said the Moderna vaccine saved 3.9 lives and caused 10.8 deaths per 100,000 vaccinations.

The papers authors based this conclusion on data from the Pfizer and Moderna COVID-19 vaccine clinical trials in the United Statesand reports of adverse effects from the United Kingdom. Although the datasets came from two different countries, the paper said, "it is unlikely that the adverse event rates would be different between the two populations."

The adverse effects reports came from the U.K.s Yellow Card system, which lets members of the public report suspected safety concerns related to vaccines, medicines and medical devices.

This system is similar to the U.S. governments Vaccine Adverse Event Reporting System, which the paper also cites to suggest the COVID-19 vaccines are unsafe.

With VAERS, anyone can report health effects after a vaccination, whether or not those effects are caused by the vaccine, the CDC said. And unlike other government data sources, these reports arent screened before theyre made public, making VAERS fertile ground for vaccine misinformation.

Paper relies on several debunked claims

The paper claims the mRNA COVID-19 vaccines did not undergo adequate safety and efficacy testing.

This is inaccurate. We have rated multiple claims about this False or Pants on Fire, including that mRNA technology was never tested in humans; that the vaccines were released after only two months of testing in healthy humans; and that a safe vaccine cant be developed in eight to 10 months.

The Pfizer-BioNTech and Moderna mRNA COVID-19 vaccines were thoroughly evaluated in clinical trials before receiving emergency use authorization from the U.S. Food and Drug Administration in December 2020. Since then, public health authorities have continued to closely monitor the vaccines safety.

"These vaccines have met rigorous scientific standards for safety and effectiveness. The available data continue to demonstrate that the benefits of these vaccines outweigh their risks," said Cherie Duvall-Jones, an FDA spokesperson.

Another claim in the paper is mRNA vaccines contain "DNA contamination." We previously fact-checked a similar claim and rated it False.

Decades of research has shown that the "biologically insignificant amounts of DNA" in the vaccines pose no known safety risk, said Dan Wilson, senior associate scientist at Janssen, which also developed a COVID-19 vaccine. Wilson also hosts "Debunk the Funk with Dr. Wilson," a YouTube show that covers science misinformation.

Its not unusual for vaccines to contain DNA fragments. The measles, mumps, rubella, varicella and rotavirus vaccines also have minuscule amounts of DNA, said Dr. Paul Offit, director of the Vaccine Education Center and infectious diseases physician at Childrens Hospital of Philadelphia.

The chance that these DNA fragments could integrate into a persons DNA is "zero," Offit said. "So, its just all a lot of hand-waving."

The paper also claims the spike proteins produced by COVID-19 vaccination linger in the body and cause adverse effects. PolitiFact has fact-checked several false claims that the spike proteins are harmful or toxic.

All coronaviruses, including COVID-19, have spikes known as spike proteins on their surfaces, which the viruses use to bind to cells and cause infection, the CDC said.

The mRNA vaccines contain neither the COVID-19 virus nor the spike protein. The vaccines mRNA technology gives the body genetic instructions for producing copies of the spike protein, which are harmless. Then, the body breaks down the mRNA and it leaves the body as waste.

The spike proteins trigger the bodys immune response, sparking antibody production. This helps the body recognize and fight off the real COVID-19 virus in future infections.

Schaffner said the spike protein claim is "far-fetched" because theres no evidence the spike protein produced from the vaccines has caused adverse effects.

COVID-19 vaccines have saved millions of lives

Public health authorities in the U.S.and worldwide have repeatedly found COVID-19 vaccines to be safe and effective.

The World Health Organization reported that as of November, more than 13 billion doses of the COVID-19 vaccine had been administered worldwide. In the U.S. alone, more than 676 million doses of the vaccine had been administered as of May.

In 2021, the first full year the vaccines were widely available, the WHO estimated that COVID-19 vaccinations saved more than 14.4 million lives worldwide.

In rare instances, adverse effects, including myocarditis, or inflammation of the heart muscle, have been linked to mRNA COVID-19 vaccines, the CDC said. Myocarditis cases were more common among adolescent and young men within a week of receiving a second dose of the COVID-19 vaccine. Most patients had mild cases and recovered quickly.

Our ruling

An Instagram post claimed a research paper shows that "mRNA COVID-19 vaccines caused more deaths" than lives saved.

Experts said the papers conclusion is based on false and misleading claims. These claims have been repeatedly fact-checked and rated False by PolitiFact and other news outlets.

The COVID-19 vaccines have been rigorously tested and monitored for years and public health authorities worldwide continue to find them safe and effective. Billions of doses have been administered worldwide. The vaccines have saved millions of lives, and adverse effects are rare.

We rate this claim Pants on Fire!
