Traditional vaccines have relied on exposing people to an inactivated (killed) or attenuated (weakened) virus.

As the immune system reacts to a non-threatening inoculation, it gains the ability to fight off infection from the real pathogen. The Pfizer and Moderna vaccines don’t include any virus at all. Instead, they use genetic code — messenger RNA or mRNA — to activate a few of our own cells to become spike-protein factories.

The vaccine consists of tiny strands of mRNA encased in fat — a lipid particle — that allows them to slip inside a cell without being attacked. Once inside, the mRNA functions roughly like computer code, instructing cells to begin assembling coronavirus spike proteins out of amino-acid building blocks already in our bodies.

The presence of these strange proteins triggers our immune systems to create antibodies to neutralize them.

Our immune system also summons T-cells to attack and shut down cells that were coded to produce spike proteins. Together, these immune responses prepare the body to fight off a real potential coronavirus infection.

“It’s very elegant,” says Jha of the vaccine design. “It’s also de-risked it a lot. There’s no physical way to get Covid from this thing.”

As for the conspiracy theory that an mRNA vaccine alters your own genes? “It literally doesn’t,” he says. “It doesn’t become part of your DNA.”
