The Geneva-based WHO is leading a global initiative to develop safe and effective drugs, tests and vaccines to prevent, diagnose and treat COVID-19. The respiratory illness caused by the novel coronavirus has infected 4.19 million people around the world, according to a Reuters tally. "We do have potentially positive data coming out but we need to see more data to be 100% confident that we can say this treatment over that one," she added. More than 100 potential COVID-19 vaccines are being developed, including several in clinical trials. The WHO said in April a vaccine would take at least 12 months.
