Adverse event puts Oxford vaccine trials on hold

Global human trials of the University of Oxford’s promising coronavirus vaccine have been paused, after a trial participant suffered an unexplained illness.
The vaccine, AZD1222, is one of two that the Federal Government will buy for Australians and is expected to be available before mid-2021, should clinical trials be successful.
But the randomised controlled phase 3 trials were suspended for a review of safety data by an independent committee, after a potentially adverse event in a single recipient in the UK was flagged.
Manufacturer AstraZeneca is hopeful the review will have minimal impact on the timeline for the leading vaccine candidate.
