As Covid infection rates hit record highs, the government is pinning its hopes on the Oxford/AstraZeneca jab, which is cheaper to produce, and easier to store and transport.
Argentina, which gave emergency approval to the Sputnik V vaccine on December 23, is now the fourth country in Latin American to launch a vaccination campaign, after Mexico, Costa Rica and Chile.
Costa Rica projects to close the year with 80,000 criminal complaints, a lower number than that registered in 2019, which accounted for more than 100,000.
More than 40 countries are still banning or restricting travel from Britain in a bid to contain a new strain of the coronavirus believed to spread faster.
