Moderna, the maker of the second COVID-19 vaccine to see emergency use approval in the U.S., is now looking to create a dual vaccine against the flu and the novel virus, the company’s chief executive recently said. Moderna CEO Stephane Bancel said Tuesday that such a jab could be ready for use in a couple of years, though it would be subject to standard regulatory approval from the FDA, not emergency use as its existing coronavirus vaccine was, he said during The Wall Street Journal Health Forum.
