The vaccine which is developed by sinovac,a private pharmaceutical firm in China is the 3rd in the world to enter phase 3 trials.

Brazil will begin advanced clinical testing of a Chinese-made vaccine against the new coronavirus on Tuesday.

the first doses will be administered to around 900 volunteers, officials said.

The coronavirus vaccine is developed by private Chinese pharmaceutical firm Sinovac

the vaccine is the third in the world to enter Phase 3 trials, or large-scale testing on humans — the last step before regulatory approval.

It will be administered to doctors and other health workers who volunteer for the program across six states in Brazil, one of the countries hit hardest by the pandemic.

the governor of the state Joao Doria told a news conference that the “Trials of CoronaVac, one of the vaccines that have advanced furthest in testing in the world, will begin at the Clinical Hospital of Sao Paulo,”

He said initial results were expected within 90 days.

Sinovac is partnering with a Brazilian public health research centre, the Butantan Institute, on the trials.

If the vaccine proves safe and effective, the institute will have the right to produce 120 million doses under the deal, according to officials.

“In Brazil, we could have the first vaccine to be put to widespread use, which is very, very promising,” said the head of the Butantan Institute, Dimas Covas.

Brazil is the second-hardest-hit country in the coronavirus pandemic, after the United States.

Its death toll surpassed 80,000 on Monday, and it has registered 2.1 million infections.

Those grim figures make it an ideal testing ground for potential vaccines, since the virus is still spreading quickly.

Brazil is also helping carry out Phase 3 testing of another experimental vaccine, developed by Oxford University in Britain and pharmaceutical firm AstraZeneca.

Another vaccine, developed by state-owned Chinese company Sinopharm, also entered Phase 3 trials this month in the United Arab Emirates.

They are the three most advanced of the dozens of projects worldwide by scientists racing to develop and test a vaccine against the new virus.

A fourth, existing vaccine against tuberculosis is also in Phase 3 trials in Australia as a potential coronavirus immunization.
