Egg has skyrocketed over the past year and this is prompting some social media users to develop wild conspiracy theories. ??? #actualités #oeufs #theoregonian #inflation
The claim misrepresents a 2021 made through an organization of Chinese researchers who immunized birds with part of the coronavirus’s spike protein to extract antibodies from the yolks of bird eggs.
“AVOID COVID!Do you know why governments are playing with poultry feed and destroying egg farms?” wrote one Twitter user who shared a screenshot of the study, which has been filed with the National Library of Medicine.
The post refers to other debunked claims that poultry feed is being replaced by egg production and that fires are being set at feed factories to create shortages.
While the message implies a link between the study and the existing egg shortage, the two have no connection to each other, experts say.
“Eating eggs that contain antibodies opposed to SARS-CoV-2 is completely opposite to COVID-19,” said Peter Palese, a professor of microbiology at Mount Sinai Icahn School of Medicine, who conducted similar research. “Such antibodies taken orally are digested in our digestive tract. “
The study, titled “Chicken egg yellow antibodies (IgY) block the binding of SARS-CoV-2 spike protein variants to human ACE2,” was published in January 2021. Investigators did not respond to requests for comment.
The study describes how antibodies that oppose the coronavirus spike protein were removed from the birds’ egg yolks. However, this was achieved by first immunizing the hens with part of the spike protein.
The antibodies were not naturally provided in chickens and would not have a profound effect on COVID-19 in humans, according to Palese.
“Such antibodies are smart laboratory reagents, but they are not smart to inject into humans,” he wrote in an email to the AP. Daria Mochly-Rosen, a professor in the Department of Chemistry and Systems Biology at Stanford University School of Medicine, showed that hens will first have to be immunized with a protein derived from the virus in order for antibodies to be provided in their egg yolks.
Even then, he said, the antibodies want to be purified from raw eggs.
In a study published in the journal “Virus” last year, a team of researchers from “hyperimmunized” birds collected their eggs to discharge antibodies.
These antibodies were used in a lab to perform virus neutralization tests, said Dr. Rodrigo Gallardo, a professor at the University of California, Davis School of Veterinary Medicine who contributed to the research.
The team found that the antibodies needed to neutralize the action of the virus on cells in vitro, however, Gallardo noted that not all eggs involve antibodies capable of neutralizing COVID. Gallardo said.
It showed that existing egg shortages caused by an outbreak of H5N1 bird flu resulted in the loss of tens of millions of poultry. double during the last year.
