Coming up with a vaccine to halt Covid-19 in a matter of months isn’t the only colossal challenge. The next big test: getting billions of doses to every corner of the world at a time when countries increasingly are putting their own interests first.

In one arrangement, developers would agree to provide shots at affordable prices in return for funding commitments from governments or other donors.
The stakes are immense with the coronavirus sickening more than 3 million people, even as billions hide from the pathogen indoors.
