A coronavirus vaccine produced by Chinese company Sinovac is 78% effective, Brazil officials announced Thursday.
Why it matters: Regulators in other countries are closely following the Phase 3 trials in Brazil. If the vaccine is approved for use, it could help fill a gap in access to coronavirus vaccines for many low- and middle-income countries.
Details: Brazil’s Butantan Institute, a medical research institute in São Paulo, conducted the study of the vaccine, named CoronaVac, with 12,476 volunteers.
· The vaccine prevented all participants from developing severe cases of COVID-19, officials said.
· Brazil has the third-highest number of cases in the world after the U.S. and India, data from Johns Hopkins University shows.
· The Butantan Institute said it will request authorization for emergency use of the vaccine in Brazil, per the Wall Street Journal.
· Other countries, including Turkey and Indonesia, are also testing the CoronaVac vaccine.
The big picture: Sinovac has already sold over 300 million doses, primarily to low- and middle-income countries, per New York Times.
· Sinovac says it will be able to produce 600 million doses this year.
