Chinese-made vaccines not effective against Delta variant after one dose

[cclub75]

Meanwhile... no one is wondering... China used its vaccine a lot on the domestic level (hundreds of millions of doses)... But how strange... the terrible Delta virus... doesn't seem able to spread overthere...

 

3 or 5 cases in megalopolis like Beijing... the first one... in six months !

... But then nothing.

 

Despites the fact (everybody say it worldwide) that this variant is extremely contagious.

 

And even islands like Australia and New Zealand with extreme mesures are defeated by the virus. It can spread anyway.

 

But not in China.

 

How lucky they are.

 

Must be the air. The water they drink, perhaps combined with Sinovac.. Strange chimical reaction that protects the population ? ????

One day I read an article on Yaho????o that the Sino was very effective against the Delta, today it is only 13% percent maybe that is the reason the Thai government not mixing and matching 1st shot Sino, 2nd AZ, yet the leaders are too scare to say anything negative to the Chinese and continue to buying the useless stuff. 

 

Reality if the vaccine effect that explains why China still using lockdown measures throughout their country?

Just had my 2nd Sinopharm, now planning a booster, Astrazeneca or Pfizer

 

A week ago I saw a chart that had a better break-down of the different combinations of vaccines including boosters, but can't find it. The one below is the closest that shows the difference. The other illustrated that taking two Chinese or a Chinese and AZ then AZ as a booster had a very significant increase in effectiveness. But the two Chinese on their own or as a booster did not much.

 

Two Sinovac doses boosted immunity to around 117 AU while two AstraZeneca boosted it to 207. However, with the Sinovac-AstraZeneca cocktail, immunity soared to an average of 716.

Meanwhile, two shots of Sinovac followed by an AstraZeneca booster saw recipients’ immunity surge to 1700.

Sinovac then AstraZeneca offers higher immunity than 2 doses of same brand (nationthailand.com)

Just better than other countries at hiding their caseload.

My step son says people have died from these shots and get 100,00 BT compensation? True?

[Johnny Mac]

''The research shows that two doses are the minimum necessary to fight the new Delta variant and prevent severe symptoms, said Zhong Nanshan, China’s leading epidemiologist and co-author of the study.''

 

 

No really? I mean, really? Real groundbreaking stuff that, amazing insight from the  leading epidemiologist. many thanks.

[Walker88]

I'm wondering if someone is going to file a suit against China in the World Court or some other body to hold the country to account for Covid and its spread. The suit could argue that China blocked and censored news of the virus, plus---since it began to hit hard at the start of Lunar New Year---China allowed it virus-carrying people to spread Covid around the world.

 

Perhaps no major country with $billions in investments in China would be willing to file such a suit, but countries with no Chinese investment but whose people and economies have been wracked by the virus could bring such a suit.

 

Certainly it is time China be held accountable for its abject failure to tell the world, when deaths and economic destruction might have been mitigated, that a serious virus was on the loose and out of control. Instead, China censored even the doctors and lab techs who discovered it. That is inexcusable.

Breaking news—virologists have determined SinoVac safe and effective for the Delta variant—as long as you receive monthly doses for the rest of your life.

Whatever the merits of the research, the title of the article is ridiculous and obviously biased. It's commonly the case that a first dose has very low effectiveness. In reporting infections, symptoms, and mortality  in  cases where 2 inoculations are required, epidemiologists make a point of distinguishing, between those who have had 1 dose or 2. And, of course, allowing enough time for the 2nd vaccine to take effect. Yet the author of this article chooses to make the headline all about effectiveness after the 1st vaccination. If you're going to cover this story, then it should be about the effectiveness after the 2nd dose which was claimed to be 59 percent. And if you don't trust the results of the study, then don't cover it at all. Clearly, this reporter, or the editor, at thaiger.com, is either clueless or blinded by bias. Or, as is most likely the case, both.

The research shows that while two shots of the Chinese vaccines are effective at, 59 per cent in preventing the Delta strain and 70.2 to 100 per cent effective at preventing severe symptoms caused by the variant,

So not far from Pfizer and Moderna which are 66% effective against the Delta variant. Second shot of Sinovac and Sinopharm at interval of only 2-4 weeks. The important facts missing.

But it is a very small study. Bigger studies where Coronavac is being used and the Delta variant is the predominant one are needed.

Large studies of Corona-vac efficacy against symptomatic infection and severe sickness done in few countries and reported in the Lancet study before Delta. You right that larger studies against Delta are needed but doubt that are being pursued with earnest as many countries are putting more focus on booster or mixing vaccines. Vaccine manufacturers are also re-designing the original vaccine against future variants which we can expect to be more troublesome. Corona-vac studies are patchy, but we can't ignore its usefulness.

The OP is misleading as it was a very small group study

 

Caveat, small sample group cohorts and study conducted in Guangzhou city

 

Summary:

 

1 dose of vaccine provided very little protection against infection (13.8%).  

2 doses age adjusted 59% against infection, 70.2% against moderate disease and 100% against severe disease (caveat very small group). Additional caveats, study cohort relatively young may overestimate protection vs. delta.

 

Obviously with small groups in this study the effect in large real world settings would bring down numbers significantly so as an example the 100% protection against severe disease would come right down.

 

Study is here: 

https://www.tandfonline.com/doi/full/10.1080/22221751.2021.1969291

 

Here's another recent study.

 

This is a useful study on Sinovac (Coronavac) that measured both the waning of antibodies and t cells. This however was not with Delta so results would be less.

 

In Brazil, Chile, China, this may be compounded by low antibody and low T-cell response from the Coronavac vaccine -- frighteningly so in males over 55 years age

Personally, i think the best study China could help with is WHO scientists being allowed unhindered access to the Wuhan labs to find out for the future good of humanity, how and why this horror was visited on the world.

There will be many people out there now who have had a single Vaccination of Sinovac and were told they now had Immunity, who will be bricking it right now.

How many was it exactly that were single Vaxxed on Phuket to ensure Sandbox Safety ?

Oh the lies and deception, and above all the betrayal of the Thai population.

Who was being told that they had immunity? If that's the case, why were they being given 2nd appointments?

Not only that, after 2 shots, Sinovac's half life is only 40 days. No wonder so many are getting infected.  I have 2 friends now in ICU with Covid. Both have had their 2 shots of Sinovac.

 

It's funny to see that the studies or the materialabout all vaccins that journalists report to us focus only on the level of anticorp in the body. It is normal for a vaccinated person who has not been in contact with the disease to see their levels of anticorp specific to this disease decrease. For example we have all received a dose of vaccine against tuberculosis, if we test your antibody level there is a good chance that we will not detect it. This does not mean that you are no longer protected. The anticorp its produced by the B lymphocites itself stimulated by the T lymphocites. Once the infection stop the levels of anticorp and lymphocites decreases. If your body is attacked again by this virus, which you have been immune to, your body will respond quickly, because T and B lymphocytes are memory immune cells. this is called immune memory and the only way to know if it is still active is to confront yourself with the virus.

 

European studies have shown that 99% of vaccinated people who are in intensive care are people who are immunosuppressed .....

I am looking forward to the DNA vaccine thats in the works for my 4th dose.  It just came to mind that I didn't take my flu vaccine this year. no one had the flu.
