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. [45][46] It is authorized for use ...
Unlike other vaccine-preventable respiratory pathogens, RSV has proven challenging for vaccine development. Ongoing efforts focus on creating vaccines that confer durable protection, with field trials eagerly anticipated. Currently, supportive care is the mainstay for treating RSV disease, as effective vaccines and antiviral drugs are awaited.
An mRNA vaccine 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 would normally be produced by a pathogen (such as a virus ) or by a ...
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 ...
N1-Methylpseudouridine is the methylated derivative of pseudouridine. It is used in in vitro transcription and for the production of RNA vaccines. [3][4] In vertebrates, it stimulates significantly less activation of the innate immune response compared to uridine, [5] while the translation is stronger. [6][7] In protein biosynthesis, it is read ...
How COVID‑19 vaccines work. The video shows the process of vaccination, from injection with RNA or viral vector vaccines, to uptake and translation, and on to immune system stimulation and effect. Part of a series on the COVID-19 pandemic Scientifically accurate atomic model of the external structure of SARS-CoV-2. Each "ball" is an atom. COVID-19 (disease) SARS-CoV-2 (virus) Cases Deaths ...
A conjugate vaccine is a type of subunit vaccine which combines a weak antigen with a strong antigen as a carrier so that the immune system has a stronger response to the weak antigen. Vaccines are used to prevent diseases by invoking an immune response to an antigen, part of a bacterium or virus that the immune system recognizes. [ 2 ]
The whole-cell pneumococcal vaccine consisted of inactive Streptococcus pneumoniae RM200 cells [9] and was the first whole-cell vaccine used against S. pneumoniae. In 2012, Phase-I studies were conducted by combining the whole-cell vaccine with alum . 1 out of 42 experienced adverse reactions which were not related to vaccination .
