Dec 6, 2023 · Even after the billions of doses given during the pandemic, messenger RNA (mRNA) vaccines still hold surprises. A study out today reveals they may unexpectedly prompt cells to produce small amounts of unintended proteins.

The vaccine delivers molecules of antigen-encoding mRNA into cells, which use the designed mRNA as a blueprint to build foreign protein that would normally be produced by a pathogen (such as a virus) or by a cancer cell.

mRNA—or messenger RNA—is a molecule that contains the instructions or recipe that directs the cells to make a protein using its natural machinery. To enter cells smoothly, mRNA travels within a protective bubble called a Lipid Nanoparticle.

Oct 6, 2021 · Messenger RNA, or mRNA, was discovered in the early 1960s; research into how mRNA could be delivered into cells was developed in the 1970s. So, why did it take until the global COVID-19 pandemic of 2020 for the first mRNA vaccine to be brought to market?

Penn Medicine mRNA research built the historic COVID-19 vaccines. Explore the history of mRNA technology and its impact on treating infectious diseases.

Nov 1, 2021 · The very first vaccines approved in the US to prevent COVID-19 were an entirely new type: mRNA vaccines. Over the past year, the Pfizer/BioNTech and Moderna mRNA vaccines have proven unusually effective and safe. How do mRNA vaccines differ from traditional vaccines, and what makes them so exciting? How traditional vaccines work

Messenger RNA (mRNA) technology has revolutionised the field of medical science, most notably during the global Covid-19 pandemic. While the technology itself is not new, its application in vaccine development has been a game changer.

mRNA vaccines work by introducing a piece of mRNA that corresponds to a viral protein, usually a small piece of a protein found on the virus’s outer membrane. (Individuals who get an mRNA vaccine are not exposed to the virus, nor can they become infected with the virus by the vaccine.)

At Moderna, we are delivering on the promise of mRNA science to create a new generation of transformative medicines for patients.¹. Scientists have been studying mRNA for decades. And mRNA vaccines are just the start. An mRNA can teach the body how to make a specific protein that can help your immune system prevent or treat certain diseases.

mRNA holds significant promise in gene therapy, in the control of emerging pandemic infectious diseases, and in diseases where no effective cure or treatment is available, avoiding several problems associated with therapies based on DNA or …
