Moderna also investigated a multivalent booster, mRNA-1273.211, which combines a 50-50 mix of mRNA-1273 and mRNA-1273.351. [ 197 ] [ 198 ] A bivalent version of the vaccine containing elasomeran/imelasomeran (Spikevax bivalent Original/Omicron) [ 54 ] was approved for use in the United Kingdom and in Australia in August 2022.
The COVID-19 mRNA vaccines from Moderna and Pfizer–BioNTech had short-term efficacy rates of over 90 percent against the original SARS-CoV-2 virus. Prior to mRNA, drug trials on pathogens other than COVID-19 were not effective and had to be abandoned in the early phases of trials. The reason for the efficacy of the new mRNA vaccines is not clear.
In December 2018, Moderna became a public company via the largest initial public offering of a biotechnology company in history, raising $621 million by selling 27 million shares at $23 per share. [25] [26] The first mRNA vaccine developed by Moderna was for influenza in 2015, and its first antibody encoded by mRNA was in 2019. [6]
mRNA-1283 is a COVID-19 vaccine candidate developed by Moderna. [ 2 ] [ 3 ] Compared to prior mRNA vaccines, this candidate has a storage temperature of 2-5 °C, compatible with vaccine storage in a standard refrigerator, rather than low temperature freezers. [ 4 ]
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.

The Moderna COVID-19 vaccine, also known as Spikevax, [318] is an mRNA vaccine [319] produced by the American company Moderna, the U.S. National Institute of Allergy and Infectious Diseases, the U.S. Biomedical Advanced Research and Development Authority, and the Coalition for Epidemic Preparedness Innovations.
An important field of application are mRNA vaccines. Replacing uridine with pseudouridine to evade the innate immune system was pioneered by Karikó and Weissman in 2005. [ 15 ] [ 16 ] They won the 2023 Nobel Prize in Physiology or Medicine as a result of their work.
