Dr. Oleksandr Molchanov poses in a hall at a hospital in Kakhovka, Ukraine, on Friday, Oct. 29, 2021. Ukraine, with one of Europe's lowest vaccination rates and a struggling and underfunded health care system, is setting records almost daily for coronavirus infections and deaths. "We are extinguishing the fire again, we are working as at the front, but our strength and capabilities are limited," Molchanov said. "We are working to the limit." (AP Photo/Evgeniy Maloletka)
