The article discusses a study by Martin Alberer and colleagues published in "The Lancet" periodical, focusing on the use of mRNA vaccine to treat infectious diseases in human beings. Topics discussed include the injection of doses of an mRNA encoding rabies virus glycoprotein in the study, the...
So one self-amplifying mRNA molecule can produce many more. The idea of a vaccine that copies itself in the body might sound a little, well, unnerving. But there are a few things I should make clear. Although the genes that give these vaccines the ability to self-amplify come from ...
Two mRNA vaccines from Pfizer and Moderna are nearing final approval, and both work by rewiring a genetic trigger. SARS-CoV-2, the virus that causes COVID-19 (coronavirus), has a unique physical structure that can be used to prime immune response. An mRNA vaccine has never been appr...
The two are now known for doing important work on the Pfizer-BioNTech vaccine against the coronavirus. But they started their company to work on a cure for cancer. In fact, the doctors started a different company about 20 years ago...
Emma Keeling talks to the U.S. scientists behind Corbevax, a patent-free brewed vaccine that's grown in yeast. This technology is far simpler and more readily available than vaccines using MRNA, and could be a potential game changer in making COVID-19 vaccines more availabl...
We show here that the mRNA from anti-COVID vaccines is not detected in human breast milk samples collected 4-48 hours post-vaccine. These results strengthen the recommendation of ABM and WHO that lactating individuals who receive the anti-COVID-19 mRNA-based vaccine should continue to breast...
The vaccine contains plasmid DNA, circular strands of genetic material that enter the host cells’ nuclei, where they’re converted into messenger RNA (mRNA). The mRNA then travels out of the nuclei into the cytoplasm and is translated into the SARS-CoV-2 spike protein, as in now-familiar ...
are a way to prevent disease.Vaccines introduce an inactive or altered form of a pathogen into the body. The altered pathogen contains the same antigen ( protein on the surface ) as the real disease causing agent. White blood cells produce antibodies specific to the antigen in the vaccine. ...
As part of “Operation Warp Speed,” the federal governmentawarded Moderna $472 millionto cover the development of mRNA-1273 through the regulatory approval process. The government has now provided Moderna with a total of $955 million to fund the vaccine’s development, including the current phase...
The extra immune firepower mRNA vaccines provide could also yield more durable protection. "We could probably generate a flu vaccine that could theoretically protect us for five years instead of just one," Pekosz says. Indeed, he believes the COVID-19vaccineeffort's success heralds a bright fut...
