Oxford resumes coronavirus vaccine trial

The third-stage trials of a coronavirus vaccine being developed by AstraZeneca and Oxford University will resume after getting the green light from safety watchdogs.
The late-stage trials of the vaccine were suspended last week due to a reported side effect in a patient in the UK.
AstraZeneca on Tuesday said the studies were being paused while it investigated whether the adverse reaction was linked with the vaccine.
But on Saturday, the university said it had been deemed safe to continue. In a statement, the university said that it was "expected" that "some participants will become unwell" in large trials such as this one.
It added that the studies could now resume following the recommendations of an independent safety review committee and the UK regulator, the Medicines and Healthcare Products Regulatory Agency.
It would not disclose information about the patient's illness for confidentiality reasons, but the New York Times reported that a volunteer in the UK trial had been diagnosed with transverse myelitis, an inflammatory syndrome that affects the spinal cord and can be caused by viral infections.
The World Health Organization (WHO) says nearly 180 vaccine candidates are being tested around the world but none has yet completed clinical trials.
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 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. - BBC
