Misinformation and conspiracy theories regarding the use of mRNA vaccines in livestock continue, despite efforts of the scientific community, the Animal Health Institute and government agencies. 

Last week Drovers and AgWeb reported about a bogus claim on social media that producers are required to inject livestock with mRNA vaccines. USDA spokesperson Marissa Perry said, “There is no requirement or mandate that producers vaccinate their livestock for any disease.”

Further, the mRNA vaccines are not even available for cattle in the United States, and the National Cattlemen’s Beef Association issued a statement indicating such in an effort to tamp down the internet falsehoods.

University of Florida professor Kevin Folta appeared on AgriTalk confirming to host Chip Flory that no mRNA cattle vaccine is approved in the U.S., but researchers are working on an mRNA vaccine for swine to battle porcine reproductive and respiratory syndrome (PRRS).

“It’s (mRNA) a vaccine for the animal that, just like any other vaccine, protects the animal from disease,” Folta said. And, “It's not in your food.”

Despite Folta’s and assurances from many others in the scientific community, false accusations about the safety of meat and milk continue. Late last week one ranch group issued a press statement followed by a commentary, both filled with inaccuracies about mRNA and frosted with a coating of fear for consumers.

In the press release, R-CALF USA said after a briefing from its Animal Health Committee Chair, who “spoke with medical doctors and a microbiologist” who were unnamed, the group’s board passed a motion to bring the issue before the full membership at its next annual meeting to determine policy direction. Until then, R-CALF says mandatory country-of-origin labeling (COOL) must be adopted, because without COOL, “The American consumer has no way of knowing if the beef they are buying is coming from a country using this debatable mRNA technology in their cattle health management.”

R-CALF CEO Bill Bullard went even further in his commentary, calling the mRNA vaccine “an injection.” Additionally, he claimed that mRNA “hijacks living cells, tricking them into producing some level of immunity against human viruses.”

But the most egregious statement from Bullard seems to cavalierly tarnish beef’s safety image.

“There is great concern that living cells excrete the mRNA over time and the mRNA can then be transferred to animals and humans that have never received the mRNA injection,” Bullard wrote. “It is believed, for example, that humans can contact (sic) mRNA by eating meat from livestock that have received the injection.”

All of that is false, of course. To obtain confirmation we reached out to Dr. Jeff Savell, Vice Chancellor and Dean, Agriculture and Life Sciences at Texas A&M University, who is also a Distinguished Professor, Meat Science. He promptly put us in contact with a faculty expert. 

That would be Dr. Penny Riggs, associate professor of animal science at Texas A&M. More of her credentials later. But first, after reviewing the R-CALF releases she called them “fearmongering and misinformation.”

Quoting directly from the email Drovers received from Dr. Riggs:

“First. No mRNA vaccines are currently available for beef cattle. I understand that there are a couple of vaccines against respiratory disease and rotavirus for swine.”

“Second. No food safety risk exists for meat from animals that have received any vaccination.” [Regardless of vaccination type, proper withdrawal times should be ensured. Specified withdrawal times are based on the specific vaccine and its formulation components.]

“Third. mRNA from a vaccine will NOT be passed along in meat.”

So what about Dr. Riggs’ credentials? Start with a BS in Biology, and then a Masters in Cytogenetics from Purdue University. Then a PhD in molecular genetics from Texas A&M. 

(Here’s a crash course in just what mRNA is and the important job it does, authored by Dr. Riggs for The Conversation.)

“Riggs’ research focuses on analyses of gene, RNA and protein expression, function, and signaling that regulate or influence aspects of beef quality, skeletal muscle traits, and developmental processes in beef cattle, as well as whole genome sequencing of bacterial pathogens. She has additional interests in genome technologies and genetic modifiers of disease susceptibility and in the role of animal agriculture and biotechnology in ensuring food and nutritional security,” according to her A&M profile.

And for good measure, Riggs “conducted postdoctoral work in the radiation biophysics lab as a Texas Aerospace Fellow at the University of Houston and the NASA Lyndon B. Johnson Space Center.”

Regarding the misinformation about the safety of meat contained in the R-CALF releases, Riggs called it “unfortunate.” As agriculturalists, “we should be celebrating the advances in technology that enable more precise and effective strategies for ensuring animal health and well-being in order to continue producing the nutritious and safe meat, milk, and other animal source products that sustain life and good health.”

Riggs went on to address the commentary and press release specifically, noting they both contain numerous factual errors. The following are Riggs’ verbatim comments to Drovers:

1. mRNA itself is neither a vaccine, nor an injection. Specific mRNAs are produced in every cell of every living organism as the first step for every biological function. The mRNA is a specific and relatively short-lived nucleotide message that is translated into the proteins in our cells. The messages are destroyed in the cell after sufficient protein is made for each biological task (minutes to hours).
 

2. A vaccine is a derivative of a pathogen—such as a modified virus, a killed virus, part of a virus, or a specific mRNA copy of a small part of a virus—that can function as an antigen. That means that when the vaccine is delivered, often by injection, our bodies recognize that antigen and respond to it by making antibodies, enabling development of immunity to that original pathogen. What makes an mRNA vaccine different is that it is the minimal amount of sequence needed for eliciting an immune response. Viruses tend to mutate rapidly, so mRNA is an advantage for speedy vaccine production because the sequence can be revised as needed. Also, this type of vaccine doesn’t have to be grown – so there are fewer ingredients in the formulation that could have potential to elicit an allergic reaction. In short, the mRNA vaccine is a new tool that is very precise and can be formulated rapidly as threats emerge.
 

3. What does the mRNA in a vaccine do? THE mRNA from a vaccine DOES NOT rewrite instructions from the body’s DNA. The mRNA does not hijack the cell. 

When the mRNA enters the cytoplasm of the immune system’s sentinel cells, the normal protein-making “machinery” present in the cytoplasm reads the message and generates a protein product that is then recognized as the foreign antigen. Then, our immune system is stimulated to produce antibodies, just like any other vaccine does. 
 

4. Potential risks are very low for humans and livestock. Although vaccines are very safe and help protect people and animals from harmful viruses and other pathogens, they function by eliciting an immune response. Rarely, that triggering of the immune response may be harmful, or a person may have an allergic reaction to the materials used to formulate the vaccine – for example, people allergic to eggs should not receive a vaccine developed in eggs. So far, data only exists for the mRNA vaccines developed to protect again COVID-19 and the limited swine vaccinations. From data collected to date, the risk of adverse events compared to other types of vaccines is very low, achieving zero risk for anything is almost impossible.
 

5. NO, there is NOT “great concern that living cells excrete the mRNA over time and the mRNA can then be transferred to animals and humans that have never received the mRNA injection.”
 

6.  NO it is NOT TRUE that “for example, that humans can contact [sic] mRNA by eating meat from livestock that have received the injection.”  

This is false. These statements are unfounded fearmongering. Every morsel of food we eat that comes from plants or animals is loaded with the DNA, RNA (mRNA, rRNA, miRNA, etc), along with proteins and other contents of the cells from source organisms – no matter if it is spinach or steak. People can enjoy a great meal, digest the meat, and none of its DNA or RNA will be transferred to them. It’s just not physically possible for that to occur.
 

7. mRNA vaccines have been “in development” for a couple of decades, but mRNA is unstable and difficult to deliver as a vaccine. As a result of U.S. investments during COVID, the last hurdle was overcome – how to deliver the specific mRNA and keep it from being destroyed long enough for an immune response to occur. This is still expensive technology, but the big breakthrough enables highly specific vaccines to be formulated rapidly and deliver only what is required. However, tests have shown that even these types of mRNA molecules can’t survive very long in the cell – an estimate is that 50% of the mRNA from a vaccine is gone in about 20 hours, and completely destroyed within a few days.
 

8. NO, the COVID-19 mRNA vaccines that contain a portion of the Sars-CoV2 spike protein will not deliver mRNA to consumers who drink milk if it is injected into dairy cows. Yes, there are ways to genetically engineer animals to deliver protein products in milk – this was done in dairy goats many years ago, but it CANNOT be accomplished by an mRNA vaccine.
 

9. NO, people who eat meat from an animal treated with an mRNA vaccine, CANNOT absorb the mRNA from the vaccine in the intestinal tract.


In conclusion, Riggs wrote, “These outlandish claims are nothing more than fearmongering to push other agendas. The various state and federal proposed bills are not based on any kind of rational scientific evidence.”
