How MRESVIA works
MRESVIA is an mRNA vaccine. This vaccine contains lab-made mRNA (genetic information) that teaches your body to make a part of a protein found on RSV.
Your immune system recognizes that this harmless protein doesn't belong in your body. This causes your immune system to make antibodies against the protein. The antibodies tell other immune cells to get rid of it.
Your immune system learns what the RSV protein looks like. So when you get infected with RSV, your immune system is ready to fight and protect you from infection.
