Sri Lanka has decided to buy 6 million more Sputnik V vaccines, raising the total it plans to purchase from Russia to 13 million doses. The government plans to inoculate 14 million people out of Sri Lanka's population of 22 million, and so far has approved the vaccines from Oxford-AstraZeneca, Sputnik V and China's Sinopharm. Cabinet ministers approved the health minister's proposal for the purchase, Cabinet spokesman Keheliya Rambukwella said Tuesday. It comes two weeks after the government said it would buy 7 million Sputnik V doses at a cost of $69.65 million.
