Close to 40 million Covid-19 vaccine doses have already been distributed through the COVAX Facility, half of them in Africa, but vaccine supplies are still stalled due to "tremendous demand" especially in India, the World Health Organization (WHO) said. COVAX, a WHO-led program to secure equitable access to vaccines for low and middle-income countries, "has, as of today, distributed just over 38.7 million doses and we expect to get past 40 million doses later this week," Bruce Aylward, the WHO's senior advisor to the director general on organisational change, said at a press conference on Monday, Xinhua news agency reported. "Over 40 countries on the African continent will have received doses by the end of this week, and they will receive nearly half of the doses from COVAX," he added.
