"We're going to start off and ensure Americans are taken care of first, but we're then going to try to help the rest of the world," Biden told reporters after a joint announcement with the chief executives of Johnson & Johnson and Merck about their joint effort to produce more vaccines.
"If we have a surplus, we're going to share it with the rest of the world," Biden said, adding that the United States had already committed to providing $4 billion to the COVAX global initiative to distribute vaccines in developing countries.
