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 ...
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.
[13] [11] While DNA vaccines were more frequently researched in the early years due to their ease of production, low cost, and high stability to degrading enzymes, but sometimes produced low vaccine responses despite containing immunostimulatory CpG sites, [14] [15] more research was later conducted on RNA vaccines, whose immunogenicity was ...
The human vaccine development process generally takes 10 to 15 years, whereas the animal vaccine process only takes an average 5 to 7 years to produce. [23] Albeit, the ability to prioritise potential vaccine targets and the use of studies to test safety is less in the animal vaccine production compared to human vaccines. [24]
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 ...
