Brazil plans to include China's Synovac Biotech vaccine in its national immunization program to prevent covid-19. Brazilian officials said on Tuesday.
Joe O'Doria, governor of Sao Paulo, Brazil, said the government had agreed to buy 47 million doses of the CoronaVac vaccine from China. The vaccine may be used from January 2021.
In addition to the Chinese vaccine, Brazil will also approve the vaccine from Oxford University in Britain.
According to the latest data from Johns Hopkins University, Brazil is one of the countries most affected by the corona virus. Corona has so far killed more than 154,000 people in Latin America's largest country. Brazil ranks second only to the United States and India in terms of transmission. And in terms of death, Brazil is after America.
Synovac, meanwhile, claims that two doses of the vaccine in their last-stage trial have kept people safe.
Russia and the United States are ahead of China and Britain in the race for the corona vaccine. Russia has begun using the vaccine nationally with approval.
But recently ,
A volunteer who was enrolled in a trial for the corona virus vaccine, a joint venture between Oxford University in the UK and AstraZeneca, has died. However, it has not yet been confirmed whether the volunteer died before receiving the vaccine, or whether he died after being vaccinated. It is unknown at this time what he will do after leaving the post.
Meanwhile, after reviewing the deaths, it has been decided to continue testing the vaccine at AstraZeneca and Oxford Universities. Brazilian health authorities did not provide any details on the deaths, citing privacy protocols. This information has been given in a report of BBC.
Oxford University authorities say intensive monitoring of the volunteer's death showed no safety concerns with the vaccine. But the BBC says the Brazilian volunteer who died has not been vaccinated.
In the case of the Covid-19 vaccine test, half of the volunteers received the actual Oxford vaccine. The other half were vaccinated with licensed meningitis. Neither the volunteer nor his family can find out about the vaccine. In this way, researchers can understand the effectiveness of the vaccine by comparing the results between the two groups.
British drugmaker AstraZeneca has said it will not comment on any specific incidents. However, they have confirmed that all kinds of review process has been completed.
Researchers hope that the Oxford and AstraZeneca vaccines will be the first to hit the market.
The vaccine has already been tested in the first and second stages. The third phase of the vaccine is being tested in the United Kingdom, Brazil and India.
In the case of a volunteer in the UK last month, the test was stopped due to side effects after taking the vaccine. After a few days of review, the researchers claimed that the vaccine was safe. Then the test is started again. Since then, the country's regulators have stopped testing the vaccine in the United States. A senior U.S. official, however, told Bloomberg that tests on the vaccine would begin soon.
Brazilian health authorities say they have learned of the death of a volunteer on October 19.
According to Brazilian media reports, the deceased was 26 years old. He is a physician. He was suffering from Covid-19 complications. The volunteer treated infected patients. However, the Brazilian health authority Anvisa did not confirm the media report.
Brazil plans to buy the Oxford University vaccine if it proves effective.
According to Johns Hopkins University, corona infections have been detected in 52,96,072 people in Brazil. The country ranks second in the world after the United States and India in terms of corona infection. One lakh 55 thousand 403 people have died of corona infection in Brazil.
