UN says 7 or 8 `top' candidates for a COVID-19 vaccine exist

The World Health Organization chief said Monday there are around seven or eight “top” candidates for a vaccine to combat the novel coronavirus and work on them is being accelerated. WHO Director-General Tedros Adhanom Ghebreyesus told a U.N. Economic and Social Council video briefing the original thinking two months ago was that it may take 12 to 18 months for a vaccine. “We have good candidates now,” Tedros said.
