Keywords: COVID-19; Sinovac vaccine; real-world research;
On May 31, 2021, the Wall Street Journal (WSJ) reported on the final research report of the Butantan Institute in Brazil:
After vaccination with CorovaVac, the Sinovac vaccine in Serrana, Brazil, There was an 80% reduction in symptomatic infections, an 86% reduction in hospitalizations, and a 95% reduction in deaths.
Serana has a population of 45,000. Between February and April 2021, there were 27,700 eligible adults, and 27,150 were vaccinated, accounting for 98% of the eligible population and 60% of the population of . %.
Remarks: The conditions for receiving the Kexing vaccine are: 18 years old and above, not pregnant or breastfeeding, and have no other serious health problems.
This is the first important real-world protection data of Kexing CoronaVac, and it is also the first test in the world to conduct independent and overall vaccination of the whole town residents. WSJ made three thematic tracking reports .
And this time, WSJ couldn't hide its joy!
Because this result not only confirms the protective power of Sinovac vaccine, but also affirms vaccination! The success of Sinovac's vaccine has undoubtedly given a boost to global vaccination.
This project, which was full of doubts from the beginning, finally won the praise of the harsh and unfriendly media of WSJ with data.
We have always said that Brazil is the most neglected major country in the epidemic. As of June 1, 2021, Brazil has 16.54 million people infected with COVID-19, the third in the world; 460,000 people died, the second in the world.
But if you look at the rate of infection per million population and the change, you can clearly see the severity of the outbreak in Brazil. The recently hyped and Indian epidemic, even at its worst, was only similar to the situation in Brazil at the time, far less severe than the worst in Brazil.
The point is that this high rate of infections in Brazil has been going on for a long time.
The reason for this is, of course, that its populist president extremely ignored the new crown epidemic; the president has been infected, so what else?
Brazilian president infected with the new crown virus, what happened?
Brazilian people, it's so hard. . .
The Brazilian town of Serrana, a project launched by scientists in a confrontation with the president's policies at a time when Brazil was desperate to control the epidemic: vaccinate the entire adult population of a commuter town and see what happens.
This is also the first such experiment worldwide.
In February 2021, researchers in Brazil officially launched the project in the town of Serrana to vaccinate all eligible adults in the town from February to April.
The reason for choosing Serrana is that 1/4 of the town's residents need to go to another nearby city for work. One of the serious areas is .
The Covid-19 pandemic has pushed Serrana unemployment to 25% as operations have to cease, many companies have laid off workers or even closed outright, and hotels and public spaces have closed.
Despite the severity of the epidemic, it was difficult to convince the town's residents to get the CoronaVac vaccine .
Brazil President Bolsonaro says to his supporters that CoronaVac is ineffective! According to the opinion poll at that time, half of the respondents expressed their rejection of any vaccine made by and ; and supporters of the Brazilian president became the main body of rejection or even protest.
But Butantan scientists believe that CoronaVac, the Sinovac vaccine, can protect Brazilians.
These scientists have withstood various pressures. First, they reached a consensus with the administrators of the town of Serrana, and then provided a large amount of data on the vaccine to show that CoronaVac is safe and effective.
When the trial was launched, the WSJ reported immediately, the title was "Brazil turns a lifeless sugarcane town into a global COVID-19 laboratory".
Oh, lab, guinea pig,?

But less than three months. On May 9, the WSJ issued a second report, titled "A small town in Brazil beats COVID-19 with unique trial", subtitled: Pandemic spreads across (Brazil), Serrana begins Back to normal.
Indeed, as you can see from the image below, three months after vaccination (green cross) began in the town of Serrana, the outbreak in Brazil was more severe.
Only 3 months after the vaccination expectation, 27,150 residents of Serrana Township have been immunized, accounting for 98% of all eligible residents.
Compared with 3 months ago, the number of infections has dropped by 75%, and there are no deaths among fully vaccinated residents.

Mayor Serrana excitedly said:
"The numbers speak for themselves," (the numbers speak for themselves)
"It worked!" !)
Caldano, a resident of the town, said:
"At first, many people thought we were experimental mice"
"But it's been a blessing." The reason is not to sweat for the trial of the CoronaVac vaccine in the town of Serrana. Because CoronaVac was only 50% protective against symptomatic COVID-19 in clinical trials in Brazil. The Brazilian mutant P.1, together with the British mutant and the South African mutant, were listed by the World Health Organization as three early-stage mutants, accounting for 60% of the infection rate in Serrana.
With the release of the final research report by the Butantan Institute at the end of May, the WSJ finally could not hide its joy, and the title of the third report was directly "Brazil uses China CoronaVac vaccine for urban vaccination trial, causes COVID-19 deaths 95% fewer people ".
Editor's note:
Dignity comes from strength.
The Wall Street Journal's shift in coverage of China's vaccines comes entirely from CoronaVac's real-world data on protection in Serrana, Brazil.
Let's review this set of data again.
98% of eligible adults were vaccinated, accounting for 60% of the town's population; as a result, symptomatic COVID-19 infections were reduced by 80%, hospitalizations were reduced by 86%, and deaths were reduced by 95%.
Compared with the two green marks in the figure below, the epidemic situation in Brazil is directly: the number of infected people is still increasing.
re-emphasizes our persistence: in the second stage of the epidemic, the most important thing for is the vaccination rate!
The vaccine that is currently available is the best choice; the best time is when
is eligible for the vaccine.
