A study commissioned by the International Chamber of Commerce (ICC) Research Foundation has found that the global economy stands to lose as much as US$9.2 trillion if governments fail to ensure developing economy access to Covid-19 vaccines. The arrival of effective vaccines can be a major game changer in mitigating the economic, social and health consequences of the virus in the year ahead. The report also warns that evidence to date suggests that access to these vaccines is likely to be highly uneven across countries. A new study highlights the major risks to the global economy inherent in this uncoordinated approach to vaccine access. Using a sophisticated model – that builds upon an earlier NBER and IMF Working Paper – to properly the assess the economic toll of a prolonged pandemic, the research shows that no economy can recover fully from the Covid-19 pandemic until vaccines are equally accessible in all countries.
