Ukrainian pharmaceutical company Lekhim said on Tuesday it had submitted documents to the Ukrainian authorities to register China's Sinovac COVID-19 vaccine. 

Lekhim, a partner of Sinovac Biotech, has signed an agreement with China's leading vaccine manufacturer to deliver 5 million doses in Ukraine, including 1.9 million via state procurement, in the first half of 2021. But it must obtain state registration in Ukraine before starting the shipment.
