Brazilian clinical trials of a Chinese coronavirus vaccine have been suspended after authorities reported a “serious incident”.
The health regulatory center in Brazil, Anvisa, said that the incident was registered on October 29, but did not provide more details.
The latest phase of Sinovac vaccine testing is also being carried out in Indonesia and Turkey.
To date, no state has reported testing suspension.
The Sinovac vaccine is one of many vaccines being tested in their final stages.
But China has already begun to immunize thousands of people.
So far there has been no response from Sinovac.
Brazil is one of the worst affected countries by the coronavirus, with more than 5.6 million cases – the third largest in the world after the United States and India.
Brazilian authorities have reported another 163,000 victims, according to Johns Hopkins University data.
Dimas Covas, head of the Bhutan Medical Institute, which is conducting tests in Brazil, told local media that the suspension of the tests was due to a death.
However, he insisted that the death was not related to the vaccine, reports the news agency
