Moderna's CEO said Monday that the vaccine maker is working on a single-shot booster for both COVID-19 and the flu.
Stephane Bancel said that he hoped the U.S.-based company would have a combined vaccine booster ready to test in advanced research in the second quarter, saying a best-case scenario would be if the single shot covering both flu and COVID-19 would be ready for use next year.
He spoke at a panel of a virtual gathering hosted by the World Economic Forum during a session on the future of COVID-19.
"I don't think it would happen in every country, but we believe it's possible to happen in some countries next year," Bancel said.
