It is an mRNA vaccine composed of nucleoside-modified mRNA (modRNA) encoding a spike protein of SARS-CoV-2, which is encapsulated in lipid nanoparticles.
It is authorized for use at some level in many countries.
In August and September 2022, bivalent versions of the vaccine (Moderna COVID-19 Vaccine, Bivalent) containing elasomeran/elasomeran 0-omicron (Spikevax Bivalent Zero/Omicron) were authorized for use as booster doses in individuals aged 18 years of age or older in the United Kingdom, Switzerland, Australia, Canada, the European Union, and the United States. The second component of the version of the bivalent vaccine used in the United States (mRNA-1273.222) is based on the Omicron BA.4/BA.5 variant, while the second component of the bivalent vaccine version used in other countries (mRNA-1273.214) is based on the Omicron BA.1 variant.
