Flu vaccines used during the flu in 2009. This is a list of vaccine-related topics.. A vaccine is a biological preparation that improves immunity to a particular disease.A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe or its toxins.
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 ...
The first use of RNA for vaccination purposes was described in 1993 by Frédéric Martinon, Pierre Meulien and colleagues [10] [11] and in 1994 by X. Zhou, Peter Liljeström, and colleagues in mice. [12] [11] Martinon demonstrated that a cellular immune response was induced by vaccination with an RNA vaccine. [11]
RNA therapeutics are a new class of medications based on ribonucleic acid (RNA). Research has been working on clinical use since the 1990s, with significant success in cancer therapy in the early 2010s. [1] In 2020 and 2021, mRNA vaccines have been developed globally for use in combating the coronavirus disease (COVID-19 pandemic). [2]

Viral vector vaccines enable antigen expression within cells and induce a robust cytotoxic T cell response, unlike subunit vaccines which only confer humoral immunity. [7] [17] In order to transfer a nucleic acid coding for a specific protein to a cell, the vaccines employ a variant of a virus as its vector.
Self-amplifying RNA (saRNA), also termed self-replicating RNA (srRNA), is a type of mRNA molecule engineered to replicate itself within host cells, enhancing protein expression and boosting the immune response, making it a promising tool for vaccines and other therapeutic applications. As a "next-generation" mRNA, saRNA is designed to achieve ...
Bunyavirales is an order of segmented negative-strand RNA viruses with mainly tripartite genomes. Member viruses infect arthropods, plants, protozoans, and vertebrates. [2] It is the only order in the class Ellioviricetes. [1] The name Bunyavirales derives from Bunyamwera, [3] where the original type species Bunyamwera orthobunyavirus was first ...
