The World Health Organization said on Tuesday that some treatments appear to be limiting the severity or length of the COVID-19 disease and that it was focusing on learning more about four or five of the most promising ones, reported Reuters.
The Geneva-based WHO is leading a global initiative to develop safe and effective vaccines, tests and drugs to prevent, diagnose and treat COVID-19. The respiratory illness has infected 4.19 million people around the world, according to a Reuters tally.
WHO official Margaret Harris sounded a note of caution around expectations for a vaccine, however, saying coronaviruses, in general, are “very tricky viruses” that are “difficult to produce vaccines against”.
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.
She restated that the WHO, which has come under criticism especially from the United States for its handling of the pandemic, would conduct an “after-action” review that would include a “free and frank” discussion on its performance.
