Emmanuel Macron and Angela Merkel, pictured last year, are among the world leaders who signed the letter
Italian Prime Minister Giuseppe Conte, French President Emmanuel Macron and German Chancellor Angela Merkel are also among those who have signed up to the initiative.
In the open letter published in weekend newspapers, the leaders said that the funds raised would “kickstart an unprecedented global co-operation between scientists and regulators, industry and governments, international organisations, foundations and healthcare professionals”.
“If we can develop a vaccine that is produced by the world, for the whole world, this will be a unique global public good of the 21st Century,” they added.
At the same time, the signatories gave their backing to the World Health Organization in the face of US criticism of its handling of the outbreak.
Dozens of research projects trying to find a vaccine are currently under way across the world.
