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 ...

US Government Accountability Office diagram comparing a traditional vaccine development timeline to a safe, possible expedited method timeline. Great Britain formed a COVID‑19 vaccine task force in April 2020, to stimulate local efforts for accelerated development of a vaccine through collaborations of industry, universities, and government ...
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 nucleoside-modified messenger RNA (modRNA) is a synthetic messenger RNA (mRNA) in which some nucleosides are replaced by other naturally modified nucleosides or by synthetic nucleoside analogues. [ 1 ] modRNA is used to induce the production of a desired protein in certain cells.
Friday's announcement indicates that timeline is still on track, though now Pfizer is testing a third dose of its mRNA vaccine for the 2-to-4 age group and observing and analyzing that data before ...
This is a timeline of the development of prophylactic human vaccines. Early vaccines may be listed by the first year of development or testing, but later entries usually show the year the vaccine finished trials and became available on the market. Although vaccines exist for the diseases listed below, only smallpox has
It’s been nine months since Jennifer Haller, the first COVID vaccine tester, got a shot during Moderna’s Phase 1 trial. Now, Moderna and Pfizer's vaccine candidates are at the head of the race ...
