Turkey will receive its first shipment of China's Sinovac coronavirus vaccine within days as preliminary domestic tests showed it was 91 per cent effective, Health Minister Fahrettin Koca said.

Ankara in the next few days will also sign a deal with Pfizer/BioNTech for 4.5 million doses, with the option to buy 30 million more from the US pharmaceutical giant and its German partner, Koca said.

Turkey will initially receive three million doses of Sinovac and have the option for 50 million more as it begins inoculations next month, starting with healthcare workers and the most vulnerable, according to AFP.

Koca said the first shipments of the Chinese vaccine will be sent to Turkey on Sunday.
