WSJ: China's CoronaVac offer 100% protetction rate (against death) for the more deadly Brazilian P.1 variant of COVID-19

[52051]

SERRANA, Brazil—This town of 45,000 people in southeastern Brazil has been at the center of a unique experiment for the past three months: vaccinate nearly every adult against Covid-19 and see what happens.

In recent weeks, after most of the adults here got their second dose, Covid-19 cases and deaths plunged and life has started to return to normal as the pandemic continues to rage across Brazil.

All of Serrana’s adults were offered CoronaVac between February and April as part of the experiment, known as Project S. It is the first mass trial of its kind in which an entire town is vaccinated for Covid-19 before the rest of the country.

Not everyone in the town was eligible, including minors under 18, adult women who are pregnant or nursing, and others with serious health problems. Of the roughly 27,700 eligible adults, 27,150, or 98%, were vaccinated, according to town officials.

Town officials and residents said they are thrilled with the results so far. Infections are down 75% from a March peak in Serrana, while there have been no deaths from Covid-19 among the people who were fully vaccinated, suggesting CoronaVac is also effective against the aggressive P.1 variant sweeping the region.

In the waiting room of the town’s intensive-care unit, the effects of CoronaVac are already visible. “Only three weeks ago, this was so full, people had to stand,” said Lucia Elaine Caldano, the unit’s administrator, pointing to rows of empty chairs. In the past three weeks, only one person has been put on a ventilator—a woman who had refused to take the vaccine.

In April, six people died from Covid-19 in Serrana. Of those, five had only taken the first dose of the vaccine. The other victim had symptoms two days after the second dose, suggesting that the disease was contracted between jabs, according to Mayor Capitelli.

Serrana’s study promises to add clarity to a global mishmash of studies of CoronaVac. In Phase 3 trials carried out by Butantan late last year, it was found to be about 50% effective against symptomatic infections and 100% effective at preventing fatal cases.

The trial’s volunteers were all medical professionals, unlike in the Phase 3 trials of other vaccines such as the one developed by Pfizer Inc., meaning the volunteers were exposed to higher viral loads, potentially leading to a slightly lower efficacy rate, researchers said.

So basically the west finally admited that the so-called 50% effective number they reported last year in Brazil, was against an much more aggressive P.1 variant in Brazilian, and with a far more exposed group of population (the medical professionals), and even that much biased test, CoronaVac were still able to offer 100% protection rate against death, for all the high-risk medical professionals in Brazil.

Coronavirus: Sinopharm vaccine more than 90 per cent effective at preventing hospitalisation, Abu Dhabi study says

The Sinopharm vaccine is more than 90 per cent effective at keeping people infected with the coronavirus out of hospital, according to a study conducted in Abu Dhabi.

Authorities said the research found a significant decrease in the rate of new Covid-19 infections among people who received a second dose of the vaccine in the emirate.

The study, conducted by Abu Dhabi Public Health Centre, found the vast majority of those who were infected after completing the course suffered mild symptoms and did not require treatment in hospital.

The vaccine was found to be 93 per cent effective in preventing hospitalisation and 95 per cent effective against admission to intensive care, according to the research.

No deaths were recorded among people who received all doses required, Abu Dhabi Media Office said.

“The study found the efficacy of vaccination in preventing hospitalisation is 93 per cent, while the efficacy of vaccination in reducing the need to be admitted to an ICU is 95 per cent.

“The study found no deaths related to Covid-19 have been recorded in patients who received all doses required.”

Yet it was the Brazilians who said we were only 50% effective. Keep lying. I said this many many times, China is the only hope for this crisis. Nobody believed me.

No they were right.. The viral load was quite high where the trials were conducted. For example, if you start a trial in a covid facility where patients are treated, the results of any vaccine will show less than 50% efficacy. Most important thing is that whether the receiver manages the virus well, and avoids hospitalization or not.

If Chinese vaccines are successful in bringing down the hospitalizations, it is a very good sign.

Sry, I am not saying you are lying, just the press, those medics were probably infected before the vaccine was even administered. Different criteria was used to judged thee other vaccines.

Sorry but let us look at the Chilean data where a real-world study of millions of Chileans who received CoronaVac found it 67% effective against symptoms, reduced hospitalizations by 85%, intensive care visits by 89%, and deaths by 80%.

China's Sinovac COVID-19 vaccine was 67% effective in preventing symptomatic infection, data from a huge real-world study inChile has shown, a potential boost for the jab which has come under scrutiny over its level of protection against the virus.

Reducing deaths by 80% is good but others like Pfizer and AstraZeneca reduce deaths by almost 100%. The problem that Chinese vaccines have is that others are significantly better.

This study just does not have enough people to make an accurate enough conclusion.

If we take the human race as a whole, it makes no sense to argue about the merits of vaccines. Even AZ has positive implications. Stopping the spread of the virus also stops it from mutating. Even if some people die from the side effects, it would be meaningful to end the epidemic.

Yes. You are absolutely right.

As Professor Wang Linfa lab study shown:
There are typical 5 types of patients but eventually it is still dependent on one's own body immunity system.
That is why some needed a 3rd booster shot. Not that the vaccines failed or does not work. Their antibody immunity system works too slowly.

If one understand how these efficacy test are conducted using a comparison of those administrated with placebo and real vaccine, it is easy to understand why and how many vaccines got high rating.

Yes. Han Patriot is also right. It depends on the conditions, where and which nations are testng it.

We won't touch it with a 100 foot bargepole

Don't worry about it, with the way India's "vaccination" drive is going, you're never going to see a COVID vaccine in your life. Either you catch it and make it or you don't, but catch it you shall.

Besides, why do you need any coronavirus vaccine? You have Hindutva medicine:

if they trialled on the frontline workers dealing with the rabid b1 variant than ofcourse the efficacy would be lower,if the trial was conducted on civilian like me the efficacy would be almost 100% .

The biggest problem with India today is the rate which these coronaviruses are mutating. Yes. india is in big big trouble.

The greatest fear is the existing vaccines may not worked at all.

These are very desperate people and they mostly from the impoverished population.

Nothing is 100%. Real world efficiency of any vaccine is about 10 to 30 percent tops, and that too is dependent on the age of the recipient. Anything above 90% is corporate marketing gimmick.

Chinese vaccines so far are traditional technology, we have some using mRNA in the pipeline waiting for data and approval

Pfizer/Moderna use mRNA, someone really worried their long term effects

Pfizer/Moderna use mRNA, someone really worried their long term effects

AstraZeneca does not use mRNA and is just as effective at reducing hospitalisation and deaths in the UK as Pfizer, where 10s of millions of people each have been jabbed with both vaccines.

Although AstraZeneca is only 70-80% effective at preventing symptomatic infection it is nearly 100% effective at preventing deaths. Only downside is there is a 1 in 1 million risk of dying from a bloot clot by taking it if you are under 55. Over 55s it is as safe as any other vaccine out there.
