Oxford vaccine trial paused after participant falls ill

Final clinical trials for a coronavirus vaccine, developed by AstraZeneca and Oxford University, have been put on hold after a participant had a suspected adverse reaction in the UK, reported British Broadcasting Corporation (BBC).

AstraZeneca described it as a "routine" pause in the case of "an unexplained illness".

The outcome of vaccine trials is being closely watched around the world.

The AstraZeneca-Oxford University vaccine is seen as a strong contender among dozens being developed globally, said the BBC report.

Its move to Phase 3 testing in recent weeks has involved some 30,000 participants in the US as well as in the UK, Brazil and South Africa. Phase 3 trials in vaccines often involve thousands of participants and can last several years, the report added.
