The Pfizer–BioNTech COVID-19 vaccine, sold under the brand name Comirnaty, [2] [33] is an mRNA-based COVID-19 vaccine developed by the German biotechnology company BioNTech. For its development, BioNTech collaborated with the American company Pfizer to carry out clinical trials , logistics, and manufacturing.
Another variant is the RNA vaccine, which contains mRNA embedded in lipid (fat) nanoparticles. The mRNA instructs body's own cell machinery to produce the proteins that stimulate the immune response. [21] Comirnaty, the Pfizer-BioNTech COVID-19 vaccine contains thirty micrograms of BNT162b2 RNA. [22]
The COVID-19 mRNA vaccines from Moderna and Pfizer–BioNTech had short-term efficacy rates of over 90 percent against the original SARS-CoV-2 virus. Prior to mRNA, drug trials on pathogens other than COVID-19 were not effective and had to be abandoned in the early phases of trials. The reason for the efficacy of the new mRNA vaccines is not clear.
MRNA vaccines, like BionTech and Pfizer's COVID-19 shot, prompt the human body to make a protein that is part of the virus, triggering an immune response. UPDATE 4-BioNTech to build mRNA vaccine ...
A colorless oily material, it has attracted attention as a component of the SARS-CoV-2 vaccine, BNT162b2, from BioNTech and Pfizer. Specifically, it is one of four components that form lipid nanoparticles (LNPs), which encapsulate and protect the otherwise fragile mRNA that is the active ingredient in these drugs.
NEW YORK and MAINZ, Germany, August 16, 2024 — Pfizer Inc. (NYSE: PFE, “Pfizer”) and BioNTech SE (Nasdaq: BNTX, “BioNTech”) today announced top-line results from their Phase 3 clinical trial to evaluate the companies’ combined mRNA vaccine candidate against influenza and COVID-19 in healthy individuals 18-64 years of age. The ...
ALC-0159 is a PEG/lipid conjugate (i.e. PEGylated lipid), specifically, it is the N,N-dimyristylamide of 2-hydroxyacetic acid, O-pegylated to a PEG chain mass of about 2 kilodaltons (corresponding to about 45-46 ethylene oxide units per molecule of N,N-dimyristyl hydroxyacetamide).
BioNTech SE, the German biotech that developed a widely used COVID-19 vaccine with Pfizer Inc, acquired a manufacturing facility in Singapore, its first in Asia, the company said on Monday. The ...
