United Nations Secretary General Antonio Guterres called for $35 billion more, including $15 billion in the next three months, for the World Health Organization's (WHO) "ACT Accelerator" programme to back vaccines, treatments and diagnostics against COVID-19.Some $3 billion has been contributed so far, Guterres told an online event on Thursday, calling it "seed funding" that was less than 10% of what the WHO wants for the programme, formally called Access to COVID-19 Tools (ACT) Accelerator.Financial support has, so far, lagged goals, as nations or governments including the European Union, Britain, Japan and the United States reach bilateral deals for vaccines, prompting Guterres and WHO General Director Tedros Adhanom Ghebreyesus to plead.
