The World Health Organisation says almost 200 coronavirus vaccines are currently in clinical and pre-clinical testing. There are more than 963-thousand Covid-19 deaths globally. Newsflash reports that WHO director-general, Tedros Adhanom Ghebreyesus, says the overarching goal of the Covax facility that has been launched is to ensure that all countries have access to vaccines at the same time, and that priority is given to those most at risk, including health workers.
