Why do COVID vaccines need to be kept so cold?
It has to do with a very important ingredient: messenger RNA (or mRNA). The mRNA in the vaccines is genetic material that teaches our immune cells how to make the spike protein found on the virus that causes COVID-19, according to the Centers for Disease Control and Prevention (CDC). The immune system responds by creating antibodies against that specific spike protein, ultimately learning how to protect the body against the virus in the future.

Completely safe.
