Scientists seem to be close to creating a “one-and-done” vaccine that can protect against any strain of a virus with just one shot.

In a press release from the University of California — Riverside, one of the researchers behind the new RNA vaccine, Rong Hai, explained why he and his colleagues are so excited about their experimental — and allegedly universal — shot.

“What I want to emphasize about this vaccine strategy is that it is broad,” said Hai, a virologist and coauthor of a new paper on the vaccine candidate in the Proceedings of the National Academy of Sciences. “It is broadly applicable to any number of viruses, broadly effective against any variant of a virus, and safe for a broad spectrum of people.”
