The Executive Director of the World Health Organization's Health Emergencies Programme has strongly criticised countries who have not shared their excess Covid-19 vaccine doses with developing nations.
Speaking at the MacGill Summer School, Dr Mike Ryan said millions of people around the world do not have any protection from the virus and that if those in developed countries are getting boosters, or are "at the top of the queue then the queue just gets longer".
Dr Ryan was critical of pharmaceutical companies who he said are making profit by manufacturing doses for countries who have "two or three" times the supplies they need and are not sharing with the WHO's COVAX programme.
