Mexico is very close to signing a contract for Russia's Sputnik V coronavirus vaccine and the first shipment of around 200,000 doses could arrive next week, a Mexican official said on Tuesday.
Juan Ferrer Aguilar, a senior health official, was speaking at a regular government news conference a day after President Andres Manuel Lopez Obrador telephoned his Russian counterpart, Vladimir Putin, and announced Russia would supply Mexico with 24 million doses over the next two months.
The European Commission will finalise a proposal by the end of the week to require pharmaceutical firms to register their vaccine exports from the European Union, while insisting it had no plans to impose an export ban.
EU countries learnt late last week that deliveries of the vaccine from AstraZeneca, which is expected to be approved on Friday, would be some 60% lower in the first quarter than initially indicated.
There have also been reduced deliveries of a vaccine jointly produced by Pfizer and BioNTech.
South African President Cyril Ramaphosa on Tuesday urged wealthy countries not to hoard surplus Covid-19 vaccine supplies, adding his voice to calls for global production to be shared more equally.
With Africa struggling to secure sufficient vaccines to start countrywide inoculation programmes for its 1.3 billion people, the head of the international Gavi vaccine alliance meanwhile said the surplus doses that richer countries had ordered ran into the hundreds of millions.
Ramaphosa, who chairs the African Union and whose nation has recorded nearly half of the continent's coronavirus deaths, said the world needed those who had hoarded doses to release them for other countries to use.
