The WHO says 5.5 billion coronavirus vaccine doses have been administered so far, but 80% of those have been to upper- and middle-income countries. Rich countries have also offered to donate 1 billion doses to other countries, but fewer than 15% of those doses have “materialized,” Tedros said. Earlier Wednesday, COVAX managers again scaled back their target to ship doses this year, projecting about 1.4 billion doses will be available through the program by year-end — down from about 1.8 billion previously. They had originally hoped to ship 2 billion doses this year. But it also said deliveries are ramping up strongly, and another 1.1 billion doses are expected to be available by year-end through the program, up from 330 million so far.
