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 U.S.
and others have refused to join the project, called Covax. “The supply of vaccines is not going to be there in the near term, and the money also isn’t there,” warned Rohit Malpani, a public health consultant who previously worked for Doctors Without Borders.
