Prime Minister Narendra Modi, launching the country's Covid vaccination drive today, gave a shout-out to frontline workers and appeared emotional as he spoke about those who risked their lives to save lives. Looking back at the difficult times when the coronavirus pandemic first burst upon an unprepared world, PM Modi choked up as he spoke about people who could not perform the last rites of their loved ones, those who were separated from their families and the elderly who died in isolation.
