WHO praises AstraZeneca COVID-19 vaccine trial pause

The decision by AstraZeneca to pause global trials of its experimental coronavirus vaccine after an unexplained illness showed the firm was prioritising safety, World Health Organization official Margaret Harris said on Tuesday.

“This is what we want to see with trials, it is a well-run trial. Safety is always critical, it is crucial and they have looked at that in an appropriate manner,” Harris told journalists in Geneva.

Asked to react to experimental COVID-19 vaccine use in China and Russia, she said: “The WHO would like to see vaccines go head to head so we can have clear information and to see these results against each other.”
