China donated 500,000 Covid-19 vaccines to Syria on Sunday.
Damascus last week received more than 1.3 million doses of the China's Sinovac under the global Covax program.
Syrian Health Minister Hassan al-Ghabash said China provided 500,000 doses of the Chinese Sinopharm vaccine.
Speaking to journalists on Sunday, he added that health authorities have vaccinated more than 600,000 people and urged more Syrians to come forward to receive the jabs.
Chinese ambassador Feng Biao said Sunday's donation raised to 800,000 the number of Sinopharm doses provided by Beijing.
Head of Mission and WHO Representative to Syria Akjemal Magtymova tweeted: “Pleased with the arrival of the significant Covax shipment to Syria this week and hope for more deliveries soon to meet the vaccination targets to combat the pandemic.”
More than 46,000 cases, including 2,661 deaths, have been officially registered in the war-torn country, but medics and activist groups believe the actual figure is much higher.
The opposition-held northwestern region of Idlib, which has recorded more than 90,000 cases, including 2,000 deaths, says it has received almost 690,000 vaccine doses under the Covax scheme. Some 77,000 people have been inoculated.
The Kurdish administration in the northeast that receives vaccines from Damascus has registered 1,500 Covid deaths from 37,000 cases, Around 40,000 people have been vaccinated.
The medical teams and international organizations fear that the health situation may worsen with the beginning of winter, especially in the refugee camps and in regions not under the government’s control.
Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator Martin Griffiths warned last month that less than two percent of Syria’s population have been vaccinated and infections are surging.
