Ukraine, with one of Europe's lowest vaccination rates and an underfunded medical system, is continuing to struggle to contain the coronavirus outbreak.
After setting nearly daily new records for coronavirus infections and deaths earlier this month, many hospitals continue to run at near full capacity.
Four coronavirus vaccines are available in Ukraine - Pfizer-BioNTech, Moderna, AstraZeneca and Sinovac - but only 21% of its 41 million people are fully vaccinated.
Many doctors are alarmed that Ukraine has been swept by a wave of fake news and conspiracy theories about vaccines, ranging from fears about the "implantation of chips" to concerns about the safety of vaccines.
Meanwhile, the Ministry of Health of Ukraine reported that 96% of patients with severe disease were not vaccinated.
