With Americans, Britons and Canadians rolling up their sleeves to receive coronavirus vaccines, the route out of the pandemic now seems clear to many in the West, even if the rollout will take many months. But for poorer countries, the road will be far longer and rougher. The ambitious initiative known as COVAX created to ensure the entire world has access to COVID-19 vaccines has secured only a fraction of the 2 billion doses it hopes to buy over the next year, has yet to confirm any actual deals to ship out shots and is short on cash.

COVAX was set up by the WHO, alliance of GAVI and CEPI, a global coalition to fight epidemics, to avoid the international stampede for vaccines.
