Editorial: Clearing the path to vaccinating the world

Manufacturers of COVID-19 vaccines say they’re now producing 1.5 billion doses a month and will have made 12 billion doses by the end of the year. In theory, that would be enough to meet the World Health Organization’s goal of vaccinating 70% of the global population. The challenge is to ensure these vaccines go where they’re needed. Most of the doses coming off production lines appear headed for wealthy countries that will soon have more than enough.
