Ukraine is suffering through a surge in coronavirus infections. Only 16% of the adult population is fully vaccinated — the second-lowest share in Europe after Armenia's rate of slightly over 7%.
Authorities in the country are requiring teachers, government employees and other workers to get fully vaccinated by November 8 or face a suspension in pay. In addition, proof of vaccination or a negative test is now needed to board planes, trains and long-distance buses.
