The World Health Organization (WHO) has reported that 64 higher income economies have joined the COVAX Facility, its global coronavirus (COVID-19) vaccine development and manufacturing initiative, bringing the total number of participant economies to 156. The initiative aims to have ‘2 billion doses of vaccine available for global distribution by the end of 2021’. The increasing number of economies joining the COVAX Facility means that, at present, approximately two-thirds of the global population is ‘committed to or eligible to receive vaccines through the Facility’. It is believed that by ‘pooling financial and scientific resources, these participating economies will be able to insure themselves against the failure of any individual vaccine candidate and secure successful vaccines in a cost-effective, targeted way’. The United States, Russia and China are not among the countries joining the multinational effort.
