(TTXVN/Vietnam+) 08:38 05/08/2021

Các nhà khoa học Anh cho rằng các biện pháp kiểm soát biên giới có thể trì hoãn nhưng không ngăn chặn được biến thể của virus SARS-CoV-2 gây bệnh COVID-19 xâm nhập vào nước này. Tuyên bố trên được đưa ra trong bối cảnh Chính phủ Anh chuẩn bị công bố đơn giản hóa các thủ tục du lịch quốc tế trong tuần này.
