ANKARA, Nov 3 (Reuters) - Turkey will begin administering boosters to people who have received two shots of the Pfizer Inc/BioNTech (PFE.N)(22UAy.DE) coronavirus vaccine, Health Minister Fahrettin Koca said on Wednesday. Turkey has already administered a third dose to more than 11.2 million people who received two doses of the vaccine developed by China"s Sinovac, whose efficacy rate officials believe falls faster. In a statement after meeting with his science council, Koca said the booster shots for Pfizer/BioNTech recipients would begin on Thursday with the elderly, those with chronic illnesses, health workers and those in other high-risk jobs. He said 59% of the population had so far received two vaccines doses, adding: "That rate needs to get over 70% to achieve herd immunity." Turkey"s daily infection numbers have hovered around 30,000 since mid-September, while the daily death toll, which peaked at 290 in September, remains above 200. The government has attributed the high infections and death tolls to a low level of vaccinations.On Wednesday, Turkey logged 29,764 new cases and 246 deaths, according to Health Ministry data.
