Move to bring vaccine to poor countries faces trouble

LONDON: An ambitious humanitarian project to deliver coronavirus vaccines to the world’s poorest people is facing potential shortages of money, cargo planes, refrigeration and vaccines themselves — and running into skepticism even from some of those it’s intended to help most.

In one of the biggest obstacles, rich countries have locked up most of the world’s potential vaccine supply through 2021, and the United States and others have refused to join the project called Covax.
