It is one of the vaccines authorized for emergency use to prevent COVID-19 in various countries.

Development and Testing[edit | edit source]

The development of the Moderna COVID-19 Vaccine began in early 2020, following the identification of SARS-CoV-2, the virus that causes COVID-19. The vaccine uses mRNA technology, which instructs cells to produce a harmless piece of the virus, triggering an immune response.
