Based on mRNA, the COVID-19 vaccine was created by the German biotechnology firm BioNTech. Logistics, production, and clinical research were all handled for its development. People who are five years old and older, those who are twelve years old and older, and those who are sixteen years old and older are permitted to take it in some jurisdictions to prevent against COVID-19, which is brought on by infection with the SARS-CoV-2 virus. The vaccination is administered through muscle injection. It is made up of lipid nanoparticles encasing nucleoside-modified mRNA that codes for a mutant version of the SARS-CoV-2 full-length spike protein. At first, it was recommended to provide vaccinations twice, 21 days apart.
