LONDON – The World Health Organization (WHO) chief scientist said the agency is not overly concerned about the pause in clinical testing of a coronavirus vaccine developed by the University of Oxford and AstraZeneca.
Dr Soumya Swaminathan called the pause in Oxford clinical trials “a wake-up call” to the global community to realize that “there are highs and lows in research.”
Swaminathan said that initial data on vaccine candidates so far has been “very promising,” showing that the injections have caused immune responses, but added that tens of thousands of people should be tested to determine whether the vaccine can protect. safely to people from infections.
“It could be that we see some results by the end of the year, it could be next year,” he said. “We have to be a little patient and wait for the results.”
