Zurich: AstraZeneca’s pause of an experimental vaccine for the coronavirus after the illness of a participant is a “wake-up call” but should not discourage researchers, the World Health Organisation’s (WHO) chief scientist said.
“This is a wake-up call to recognise that there are ups and downs in clinical development and that we have to be prepared,” Soumya Swaminathan told a virtual briefing from Geneva.
“We do not have to be discouraged. These things happen.”
Governments are desperate for a vaccine to help end the COVID-19 pandemic, which has caused more than 900,000 deaths and global economic turmoil, and the WHO had flagged AstraZeneca’s, being developed with Oxford University, as the most promising.
