Sarah Lim, 46, is part of the team that screens suspect Covid-19 cases. “I feel grateful and thankful for being the first to be vaccinated, I would encourage them [others] to go for it,” she told reporters after receiving the shot . . . It’s not very painful.” She added in Mandarin: “I wanted to take the injection to protect myself, my loved ones, patients and the public . . . It gives me greater peace of mind.” The vaccine was removed from the fridge at 8:30am – according to a note on the wall – and delivered about an hour later after it reached room temperature. It took several minutes for the nurse who administered the jabs to prepare the injection each time.
