ANKARA, Turkey (AP) — Turkish President Recep Tayyip Erdogan said Friday that a further 10 million doses of the Chinese CoronaVac vaccine could arrive in Turkey by this weekend.

Speaking after prayers in Istanbul, Erdogan said delivery of a second batch of the vaccine had been approved by China.

Turkey has so far received 3 million doses and has vaccinated nearly 2 million people, prioritizing health workers and the elderly, since its program started a week ago. Erdogan has said he expects a Turkish-developed vaccine to be available in May.
