SM-102 is a synthetic amino lipid which is used in combination with other lipids to form lipid nanoparticles. [1] These are used for the delivery of mRNA-based vaccines, [2][3][4] and in particular SM-102 forms part of the drug delivery system for the Moderna COVID-19 vaccine. [5][6][7] Lipid nanoparticles are an extension of earlier RNA ...
A nucleoside-modified messenger RNA (modRNA) is a synthetic messenger RNA (mRNA) in which some nucleosides are replaced by other naturally modified nucleosides or by synthetic nucleoside analogues. [ 1 ] modRNA is used to induce the production of a desired protein in certain cells. An important application is the development of mRNA vaccines ...
mRNA in vitro transcription, innate and adaptive immunity activation. An mRNAvaccine is a type of vaccine that uses a copy of a molecule called messenger RNA (mRNA) to produce an immune response. [ 1 ] The vaccine delivers molecules of antigen -encoding mRNA into cells, which use the designed mRNA as a blueprint to build foreign protein that ...
The Novavax COVID-19 vaccine, sold under the brand names Nuvaxovid and Covovax, [1] among others, is a subunit COVID-19 vaccine developed by Novavax and the Coalition for Epidemic Preparedness Innovations. [31] It contains a recombinant spike protein from the SARS-CoV-2 Omicron variant lineage JN.1.
Matrix-M is a vaccine adjuvant, a substance that is added to various vaccines to stimulate the immune response. [1][2][3] It was patented in 2020 by Novavax [4] and is composed of nanoparticles from saponins extracted from Quillaja saponaria (soapbark) trees, cholesterol, and phospholipids. [5][6][7] It is an immune stimulating complex (ISCOM ...
A study provides a promising preclinical demonstration of the effectiveness and ease of preparation of Valrubicin-loaded immunoliposomes (Val-ILs) as a novel nanoparticle technology. In the context of hematological cancers, Val-ILs have the potential to be used as a precise and effective therapy based on targeted vesicle-mediated cell death.
Before COVID-19 vaccines such as Moderna and Pfizer/BioNTech were authorized for use in the general population, they had to pass phase III studies involving tens of thousands of people. Any serious side effects that did not appear during that testing are likely to occur less often than ~1 in 10,000 cases.
A lipid nanoparticle is typically spherical with an average diameter between 10 and 1000 nanometers. Solid lipid nanoparticles possess a solid lipid core matrix that can solubilize lipophilic molecules. The lipid core is stabilized by surfactants (emulsifiers). The emulsifier used depends on administration routes and is more limited for ...
