MRNA vaccines do they work?

Yes, mRNA vaccines work by instructing cells to produce a specific viral protein, which then triggers an immune response that protects against the actual virus. They are an effective new type of vaccine, though the only currently authorized or approved mRNA vaccines in the United States are for COVID-19.

How mRNA vaccines work



  1. Delivering instructions:
    The vaccine contains synthetic mRNA, which is a type of RNA that carries instructions for making proteins.



  2. Protein production:
    After the mRNA enters a cell, the cell uses these instructions to produce a small piece of a protein from a specific pathogen (like a virus).




  3. Immune response:
    This viral protein then triggers the immune system to create antibodies, which are designed to recognize and fight off the actual virus if encountered in the future.




  4. No viral infection:
    The mRNA does not enter the cell's nucleus, does not alter your DNA, and does not expose you to the virus itself, so you cannot become infected with the virus from the vaccine.
