World Health Organization said the U.N. health agency will not recommend any COVID-19 vaccine before it is proved safe and effective, even as Russia and China have started using their experimental vaccines before large studies have finished and other countries have proposed streamlining authorization procedures.At a press briefing on Friday, Tedros Adhanom Ghebreyesus said vaccines have been used successfully for decades, and credited them with eradicating smallpox and bringing polio to the brink of being eliminated.
Widespread coronavirus vaccine not expected until mid-2021: WHO “I would like to assure the public that WHO will not endorse a vaccine that’s not effective and safe,” Tedros said.
