Argentina threatens to cancel deal for Sputnik vaccine as Russia fails to deliver

Moscow owes 18.5m doses, leaving Argentina in a very critical situation' with only 12% fully vaccinated, leaked letter reveals

Argentina's gamble on Sputnik V vaccine has left it in a very critical situation" because of Russia's failure to fulfill delivery commitments, according to an official letter to Moscow leaked on Thursday.

Russia owes Argentina 18.5m doses of its Sputnik V jab, over two-thirds of them vital second-component doses.

Only 12% of Argentinians are fully vaccinated so far, partly due to failed Sputnik deliveries of its second component. Another 37% have received only a single dose.

This compares disastrously with double-dose vaccination rates of over 60% in neighbouring Chile and Uruguay, countries that did not bet so heavily on the Russian vaccine.

Its low two-dose vaccination rate leaves Argentina particularly exposed to the arrival of the Delta variant. Neighbouring Uruguay, meanwhile, has already approved moving to a three-dose regimen.
