An annual report by the Bill and Melinda Gates Foundation has found that the spread of coronavirus has pushed global development back more than two decades. Tens of millions of people face greater inequality, disease and poverty, according to the study, with many of the UN’s Sustainable Development Goals negatively impacted. Speaking to the BBC, Bill Gates said an effective vaccine was likely to be ready by early 2021. However, he stressed that any vaccine must also be made accessible to poorer countries.
