'A New Beginning': Relief, Hope as UK Begins Mass COVID Vaccinations Henry Ridgwell LONDON - Scientists and doctors say the mass coronavirus vaccination campaign that started in Britain this week represents a major milestone in the fight against COVID-19, although big challenges remain in producing and distributing enough vaccines to end the global pandemic. Britain was the first country in the world to start coronavirus vaccinations after regulators approved the Pfizer-BioNtech vaccine last week. Filipino nurse Leo Quijano, who works at the Royal Sussex County Hospital in the southern city of Brighton, received the vaccine Wednesday. She told VOA she has full confidence in it. "I feel more confident and safe, because I've been COVID positive before and I was admitted in the hospital. There are thorough studies and research before the vaccine comes out. So, I feel positive about it," Quijano said. Colleague Ashley Lecheminint works in the hospital's catering department and also received the vaccine Wednesday. "We're going to defeat this coronavirus now," Lecheminint said. "It's going to be like a new beginning." .
