US Secretary-General Antonio Guterres has reiterated his call for equitable access to Covid-19 vaccines as the global caseload has surpassed the 100 million mark, another grim milestone as the pandemic rages on. "I want to utilise this vital platform today to once again urge all countries, economies, and manufacturers to work with - and through - the COVAX facility to realize the commitments of equitable access, especially for the most vulnerable," the UN chief said in his pre-recorded video message to the High-level Webinar on the African Covid-19 Vaccine Financing and Deployment Strategy on Wednesday. "We must ensure that vaccines are seen as a global public good - people's vaccines - accessible and affordable to all," said the Secretary-General.
