Final clinical trials for a corona-virus vaccine, developed by AstraZeneca and Oxford University have been put on hold after a participant had a suspected adverse reaction in the UK.
AstraZeneca described the development as a ‘routine’ pause in the case of ‘an unexplained illness’.
The outcome of vaccine trials is being closely monitored around the world.
The AstraZeneca-Oxford University vaccine is seen as a strong contender among dozens being developed globally.
Hopes have been high that the vaccine might be one of the first to come on the market, following successful phase 1 and 2 testing.
Its move to Phase 3 testing 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.
