Brazil's half authority said on Wednesday that although the volunteer had died, the trial would continue.

So far, 8000 people have been given the first dose of the vaccine in six cities in Brazil, which is grappling with one of the world's worst outbreaks of the disease.

A source familiar with the matter told Reuters that the volunteer who died was likely to have been part of a control group that did not receive the Kovar 19 vaccine, suggesting that the volunteer was instead given a meningitis job.

Oxford University confirmed that testing would continue, adding the after careful assessment quote.

There have been no concerns about the safety off the clinical trial, but AstraZeneca declined to comment immediately.

This follows a pause in trials off the vaccine last month when a patient in the U.

K fell ill.

The trial resumed days later, but it's still on hold in the U.

S.

Also on Wednesday, Brazil's president said their federal government would not by the vaccine from China's Sina back, contradicting what his health minister said the day.

Before that, it would be included in the nation's immunization program.
