mRNA vaccines are considered one of the most effective vaccines for reducing severe infections and deaths.
While traditional vaccines use weakened or killed bacteria to prepare the body for a future attack by a real virus, mRNA deploys snippets of genetic material that carry instructions to show the body’s cells how to make proteins—in this case, stimulus. The spike protein is located on the coronavirus that causes Covid.

The body’s immune system then triggers antibodies against the spike protein, preparing it for an actual coronavirus attack.
