Messenger RNA

Messenger ribose nucleic acid (mRNA) is the RNA responsible for providing the genetic information for translation. It is the template for protein synthesis. Each set of three bases, called codons, specifies a certain protein in the sequence of amino acids that comprise the protein. The sequence of a strand of mRNA is the inverse of the sequence of a complementary strand of DNA.

This misnamed Covid vaccine was really an mRNA injection, except for the discontinued Covid vaccine made by Johnson & Johnson.

In February 2025, an Idaho Senate committee "hears 2 hours of testimony on bill to ban mRNA vaccines for 10 years."
