Moderna COVID‑19 vaccine, known by the generic name elasomeran and brand name Spikevax, is a COVID-19 vaccine. It is used in people over the age of eleven or seventeen, depending on the jurisdiction, to provide protection against COVID-19. It was initially found to be 94% effective. It is given as two or three 0.5 mL doses by injection into a muscle at least 28 days apart.

Most side effects are mild to moderate and resolve within a few days. These may include pain at the injection site, tiredness, fever, swollen lymph nodes, headache, and muscle pains. Rare side effects may include anaphylaxis, facial palsy, pericarditis, and myocarditis. There is no evidence of harm with use in pregnancy. It is an mRNA vaccine, composed of nucleoside-modified mRNA (modRNA) encoding the spike protein of SARS-CoV-2, which is encapsulated in lipid nanoparticles.

The vaccine received emergency use authorization (EUA) in the United States in December 2020 and was approved for medical use in Europe in January of 2021. It is authorized for use at some level in at least 86 countries as of 2022. In 2020 it was being sold to governments at about 35 USD per dose. It was developed by American company Moderna, the United States National Institute of Allergy and Infectious Diseases (NIAID), and the Biomedical Advanced Research and Development Authority (BARDA). It was the first COVID-19 vaccine to be studied in humans.
