Thailand’s Public Health Ministry announced the results of a real world study of the efficacy of the Chinese-made Sinovac vaccine conducted in Thailand today (Monday), showing that two doses of the vaccine are highly efficacious in the prevention of infection and death from the Alpha (UK) variant of COVID-19, at 71-91%.

 

The study was conducted in Phuket, Chiang Rai and Samut Sakhon during April and May, the peak of the spread of the Alpha strain of COVID-19 .

 

Public Health Permanent Secretary Dr. Kiattiphum Wongrachit told the media today that the study shows that the Sinovac vaccine has 71-91% efficacy in preventing infections by the Alpha variant among people tested at least 14 days after they received their second dose.

real world study

So the study did not take place in Thailand?

[edwinchester]

I await the real world tests showing it's efficacy against the Indian and South African variants.

[dinsdale]

Just more CP advertising. No mention of peer review. No mention of double blind. No mention of how many people and no mention of vaccine breakthrough which is happening.

[edwardandtubs]

The numbers are absolutely meaningless. Was this actually a double-blind placebo-controlled trial or another pointless look at the number of antibodies. These Thai studies have absolutely no credibility anymore.

[richard_smith237]

Who cares about Alpha (B.1.1.7 variant first identified in the UK)…  all the vaccines perform well against that. 
 

Delta is where it’s at !!  Specifically B.1.617.2….    This the variant generating the greatest concern at the moment. 

 

The announcement is almost irrelevant as the Delta starts to take a greater hold.

That article also fails to mention that of the 26 Indonesian doctors who have died this month, 10 were fully vaccinated with Sinovac.

just process the test result without challenging the test basis, as if any of you are qualified, despite throwing around trial method terms like you are experts..... 

result makes some sense as a brazilian trial had Sinovac at 100% effective against original covid death or hospital case.....

yes these test results are from non- western sources and are therefore unreliable.... but its good news if you chose to be optimistic & positive.

[rabas]

 

I await publication of the study and data confirming this. Otherwise it may be this week's government announcement that Sinovac is a really great vaccine.  Sinovac is based on the Wuhan strain, not Alpha, and was rated at 50.4% in it's first study in Brazil, among health care workers, like this study.

 

Sinovac: Brazil results show Chinese vaccine 50.4% effective

 

I would take Sinovac if nothing else were available, all vaccines can help, but lets be clear about facts.

[WhiteBuffaloATM]

 

best available (non- western) factual data indicates Sinovac appears to work with minimal side effects. not the best on symptoms but might be totally effective against death or hospital case......should be taken if no western vax available..... should not dismissed on emotional (fear) basis.

You also fail to mention a fact/factor in your referenced  article that it is stated  there is no record of the infection state status of any of the  26 Doctors at the time they received the vaccination because such data is/was not being compiled .

Is there a vaccine that has been demonstrated  to "cure " advanced symptomatic  infection of covid-19 ?

And 83.5% in Turkey. 
It does need more consistent trials and results but I suppose the Thai study is part of this.

And deaths of medical personnel in Indonesia have also been significantly reduced compared with earlier in the pandemic. 50 out of 117 Covid Delta variant deaths in the UK have been people who've had 2 vaccine shots. So as the article you posted makes clear you need to look into all relevant conditions when judging the overall situation.

well at least this time they have actually clarified which variant, I am sure they have data on other variants that they would rather not publish 

[wensiensheng]

It looks and sounds like propaganda to boost vaccinations. Nothing wrong with that intent, but feels a bit sneaky.

 

it specifically states after two jabs…..many people have had only one and nothing is mentioned about the efficacy after one jab.

 

the study in Phuket must have been minuscule. Even at the virus’s worst and before vaccinations, there were very very few cases.

 

as propaganda I think it’s fine, as far as medical research goes, it seems superficial. 
 

a minor distraction really, nothing earth shattering.

A person with a terminal illness can be optimistic and positive yet will still die.

you first ????

 

and then later you will need to re- vaccinate with an effective alternative were there is no telling how they will react in the body with multiple types of experimental drugs ........................................ no thanks, bad enough having to take one of these in my body never mind two

And you failed to mention the numbers of Indonesian Dr’s on the front lines exposed to the virus… in doing so you’ve avoided intelligent balance, deliberately so or through ignorance I’m not sure… 

 

Even Sinovac is as good as or close to 100% effective against death from complications arising from Covid-19…, before people jump all over that comment, that means 99.99% (close to 100%).. i.e. 10 out of 100,000 vaccinate people….

The protection offered is excellent, however, the effectiveness against the Delta variant is of concern at the moment.

You get 26 dying that means the vaccine failed 26 times and this is only in relation to deaths. How much vaccine breakthrough has there been all up and how infectious are those people? The numbers you are quoting are for which variant(s)? It would be great if you could show these numbers and bear in mind these numbers must now be relevant to the new strains. Obviously you will need to supply this info from peer reviewed studies not the nonsence in the OP. Might be difficult. Not sure how much is out there with these new strains and of course nothing is out there with new strains to come.

I have no qualms about sinovac against the original variant, so long as it’s two jabs.

 

but in Thailand it’s 88% alpha and about 10% delta, and of course delta is growing fast. Hence your comment….

 

“The protection offered is excellent, however, the effectiveness against the Delta variant is of concern at the moment. “
 

….undermines your otherwise excellently argued case.

 

I’m sure the Chinese company is working on a revised formula, just as AZ is doing for the beta variant, but here and now, sinovac seems to be of a lower rank to mRNA vaccines. Just my opinion, no medical research for that.

 

 

 

[EricTh]

What I am worried is the Indian strain which is spreading fast. How effective are current vaccines against it?

[WhiteBuffaloATM]

so 0.1 % indo doctors died after sinovax. half would have or did died of something else ?

of no concern to fit westerners with completely different lifestyle

there is no “rank” of vax.... they all appear to be practically 100% effective against death & hospital

no point worrying about variants as you have no control ;

just trust the fact that your vax is highly effective against all variants.......

ridiculous & childish to eauate Sinovac with “ Primark” or “ charity shops”; 

cease please all the fear- driven emotional negativity including the anti -vaxx nonsense

It is probably the same as those studies runin the UK, USA, etc. No, they are nto measuring antibodies. They are probably recording the percentage of people becoming infected after vaccination vs those that are not vaccinated. Similar studies are done in most countries like that. They are less rigorous than controlled studies, but they have to be, as they record data from many thousands of people. The methodology is sound if the vaccinated vs unvaccinated group have similar exposure risk, which is the assumption that needs to be made. 

[Forza2002]

Less than 5% of the Thais have had 2 jabs. Majority won't benefit from the results of this dubious study for a long time..

Covid-19: Chinese vaccines may need changes to improve efficacy, admits official

https://www.bmj.com/content/373/bmj.n969 13 April 2021

A study of the Sinovac rollout by the University of Chile reported that the vaccine was 56.5% effective two weeks after second doses were administered in the country. However, they also reported that one dose was just 3% effective (rising to 27.7% within two weeks of the second dose, and 56.5% two weeks later).5

https://thailand.prd.go.th/more_news.php?cid=2&filename=index

Thailand reports that 8,657,423 doses have been administered, equivalent to 12% of the population. The target for June is 10 million doses. In Bangkok, 19.5% of its population has already received the first dose of vaccine, while almost 9% have received the second dose. The rate of vaccination in Phuket is progressing very well, with 63% of its population already vaccinated with the first dose, while almost 50% have received the second dose. (25/06/2021)

https://www.wsj.com/articles/covid-19-killed-26-indonesian-doctors-in-juneat-least-10-had-taken-chinas-sinovac-vaccine-11624769885

This is from that Wall Street Journal article you linked to:

"Around 90% of Indonesian doctors—roughly 160,000 in all—have been vaccinated with Sinovac’s shot, according to the medical association, so the vaccinated doctors who died are only a tiny percentage of the total."

There's also this:

"Data gathered by the medical association shows the death toll among doctors is down from the country’s last surge in December and January, when vaccinations had just begun and around 60 doctors died in each of the two months from Covid-19. So far in June, 26 doctors have died."

I would take Sinovac if nothing else were available, all vaccines can help, but lets be clear about facts.

 

I might actually choose Sinovac ahead of others.  I want to steer clear of strong side effects and am pretty sure it's basically good at preventing serious infection.

You heard some terms before but really have no clue about research methods. How do you propose to run a real world trial (so not a controlled one with volunteers) with a placebo control group, and double blind none the less?  Imagine you’re having your two vaccinations, then 3 months later you get Covid and 3 months after that you were told that you were in the placebo group taking part in a trial. “Haha, Sucks to be you”. And what would your vaccination certificate say? “May or may not be vaccinated?”

[ourmanflint]

The alpha variant no longer exists in the wild. Good job Thailand
