1. RNA vaccine

   A ribonucleic acid (RNA) vaccine or messenger RNA (mRNA) vaccine is a type of vaccine that uses a copy of a molecule called messenger RNA (mRNA) to produce an immune response. The vaccine transfects molecules of synthetic RNA into immune cells, where the vaccine functions as mRNA, causing the cells to build foreign protein that would normally be produced by a pathogen (such as a virus) or by a cancer cell. These protein molecules stimulate an adaptive immune response which teaches the body to identify and destroy the corresponding pathogen or cancer cells. The mRNA is delivered by a co-formulation of the RNA encapsulated in lipid nanoparticles which protect the RNA strands and help their absorption into the cells.Reactogenicity, the tendency of a vaccine to produce adverse reactions, is similar to that of conventional non-RNA vaccines. People susceptible to an autoimmune response may have an adverse reaction to RNA vaccines. The advantages of RNA vaccines over traditional protein vaccines are ease of design, speed and lower cost of production, and the induction of both cellular and humoral immunity. While some RNA vaccines, such as the Pfizer–BioNTech COVID-19 vaccine, have the disadvantage of requiring ultracold storage before distribution, other mRNA vaccines, such as the Moderna, CureVac, and Walvax COVID-19 vaccines, do not have such requirements.In RNA therapeutics, mRNA vaccines have attracted considerable interest as COVID-19 vaccines. In December 2020, Pfizer–BioNTech and Moderna obtained approval for their mRNA-based COVID-19 vaccines. On 2 December, the UK's Medicines and Healthcare products Regulatory Agency (MHRA) became the first medicines regulator to approve an mRNA vaccine, authorizing the Pfizer–BioNTech vaccine for widespread use. On 11 December, the US Food and Drug Administration (FDA) issued an emergency use authorization for the Pfizer–BioNTech vaccine and a week later similarly approved the Moderna vaccine.The use of RNA in vaccines has occasioned substantial misinformation in social media, wrongly claiming that the introduction of RNA alters a person's DNA.

Examples of rna vaccine in a Sentence

1. Paul Offit:

   In a better world, we would have abundant quantities of this messenger RNA vaccine, Pfizer and Moderna, and that would be damning for a vaccine that's clearly less effective. But that said, we have limited quantities of mRNA vaccine.

2. Peter Sokolowski:

   The' messenger RNA vaccine' was new to me, I had never heard of it, and unless you were a research scientist, you probably haven't, therefore, Oxford English Dictionary didn't even cover a definition.
