Early morning of November 30, a large number of students from Nguyen Du Junior High School (Hang Gai Ward, Hoan Kiem District, Hanoi) were at the school to get vaccinated against the COVID-19 disease. A little bit of nervousness and worry is the feeling of Phuong Anh (a student of 8G class) when she returns to the school to get vaccinated. However, seeing friends and teachers again is the motivation for Phuong Anh and her friends to overcome that feeling. This time, 780 students of Nguyen Du Junior High School in grades 7 and 8, from 12 years old and above, would be injected with Pfizer vaccine (1 st dose). As the youngest people to be vaccinated, the screening and injection procedures for those children are also done very carefully and in accordance with the guidance of the Ministry of Health. Multiple epidemic prevention scenarios have been activated and lots of people are getting vaccinated. Hanoi is creating the best possible condition for all students and schools, so children can return to schools after a long time staying home because of the COVID-19 epidemic./.
