The vaccines made by Pfizer-BioNTech and Moderna use mRNA to fight COVID-19. When these vaccines were rolled out, it was the first time mRNA was used on humans in vaccine technology. While the concept is new to the public, the research has been around since the early 1990s. What are m...
opportunities for creating future mRNA vaccines that are tailored to fight different infectious diseases. Other scientific advances over the last two decades, such as encapsulating the mRNA into fat molecules known as lipid nanoparticles (LNPs) to protect the molecule and enhance its delivery into cell...
MRNA vaccines eliminate much of the manufacturing process because rather than having viral proteins injected, the human body uses the instructions to manufacture viral proteins itself. Also, mRNA molecules are far simpler than proteins. For vac...
mRNA, a type of genetic material that provides the instructions your cells need in order to make proteins, used to be a term mainly used by scientists. But since COVID arrived, many of us are now familiar with it thanks to the mRNA-based vaccines.
But among all the currently available vaccines across the globe, those that use mRNA may be the easiest to update against new variants, experts said. Currently available COVID-19 vaccines are designed to target one specific portion of the virus -- the so-called "spike" protein that helps the...
Because additional sequences such as plasmid backbone are lacking in mRNA vaccines, the pre-existence or induction of anti-vector antibodies is of no issue. Moreover, mRNA is produced by an in vitro transcription process without any mammalian cells, so there is no risk for adventitious viruses....
Those advances, and the challenges they solved, form the history of mRNA vaccines and how they became part of mainstream medicine. Now scientists and doctors are looking beyond COVID-19 to the almost limitless potential of nucleic-acid-based drugs. “mRNA is a very promising tool for a variet...
where vaccines are produced and distributed for public use. 疫苗将被生产和发配给大众接种。 Under regular circumstances, this process takes an average of 15 to 20 years. 在正常情况下, 这个过程会持续 15 到 20 年。 But during a pandemic, researchers employ numerous strategies ...
"The mRNA and vector vaccines are a newer technology; the first products were developed in 1999," said Mullane. "Based on our understanding of human biology, there is no reason to believe that they should pose any greater risk than any of the more traditional types of vaccines. If anything...
