Nurse Shimray Wungreichon, 43, speaks to colleagues who will administer her the COVID-19 vaccine at the District Hospital in Ukhrul, in the northeastern Indian state of Manipur, Saturday, Jan. 16, 2021. Wungreichon was among the first of many Indian health workers to be vaccinated on Saturday, opening a new chapter in the battle against the pandemic in the world's second hardest-hit country, which has been scarred profoundly by a virus that has killed more than 152,000 of its people.
