mRNA Vaccination Can Cause Unintended Proteins – Experts Give the All-Clear

According to a study, mRNA vaccines may lead to the formation of unwanted proteins to a very limited extent. There is currently no evidence that this has resulted in negative effects with the mRNA vaccines used against COVID-19, as stated by researchers led by Anne Willis from the University of Oxford in the journal “Nature.” Nevertheless, this phenomenon should be avoided in future vaccines, as it could potentially lead to negative effects such as reduced efficacy or side effects.

German experts speak of interesting results but see no reason for concern. Julian Schulze zur Wiesch from the University Medical Center Hamburg-Eppendorf (UKE) stated, “The described effect, if true, is not dangerous or alarming and most likely has nothing to do with general vaccine reactions or the side effects of mRNA vaccines.” According to him, mRNA vaccines are safe.

Marina Rodnina, his colleague from the Max Planck Institute for Multidisciplinary Sciences in Göttingen, shares a similar view. There is currently no proof that the protein fragments produced during vaccinations have negative effects on humans. However, if the production can be adjusted to avoid this phenomenon, “it should be done for the future use of mRNA technology.”

Slipped Slightly When Reading

The provided text discusses mRNA vaccines and their construction. These vaccines contain the instructions (mRNA) for a specific component of the virus targeted for protection. Ribosomes, the cellular protein-building machinery, read these mRNA molecules in human cells, assembling a viral protein based on this information. Subsequently, this protein stimulates the immune system to produce defenses against the virus.

For enhanced efficacy, the mRNA in vaccines undergoes slight modifications by the manufacturer, as elucidated by Anne Willis and her team in “Nature.” These modifications may cause the protein-building machinery to slightly deviate during the reading of the mRNA blueprint, leading to the unintended formation of proteins.

Willis’ team demonstrated in mice, using the Biontech coronavirus vaccine (BNT162b2), that an immune response against these unintended proteins occurs. A minimal degree of such an immune response was observed in a third of the 21 human subjects, with no reported side effects. However, the significance of this phenomenon is limited due to the small number of participants. Additionally, the research team outlined methods to prevent such unintended effects in the future.
