Messenger RNA sequences from the Pfizer and Moderna COVID-19 vaccines were found in the blood of multiple individuals weeks after vaccination, according to a new study.
Researchers in Denmark analyzed samples from the vaccinated and detected partial or even full sequences of the messenger RNA (mRNA) following vaccination. The sequences were found as late as 28 days after vaccination, or the longest time period the study analyzed.
The findings mean that the mRNA, which is situated in lipid nanoparticles for deliverance into the body, lingers for much longer than authorities in the United States and elsewhere acknowledge.
The U.S. Centers for Disease Control and Prevention, for instance, has claimed that the mRNA is broken down “within a few days.” The Infectious Diseases Society of America says the mRNA “is quickly metabolized and eliminated via cellular processing mechanisms.”
Henrik Westh, a professor of clinical microbiology at the University of Copenhagen, and co-authors of the new study described being surprised by the findings.
“We surprisingly found fragments of COVID-19 vaccine mRNA up to 28 days postvaccination in blood from chronic HCV patients vaccinated with mRNA vaccines from both Pfizer-BioNTech and Moderna,” they wrote.
The study featured taking samples from 108 vaccinated people with chronic hepatitis C virus, or HCV, and examining them for up to 28 days after vaccination.
Ten of the samples, or 9.3 percent, had partial or full sequences of the mRNA sequence….
