News Forum - Study: Sinovac with a Pfizer booster more effective that AstraZeneca

[Thaiger]

New studies show that between Sinovac and AstraZeneca combined with Pfizer, the most effective vaccine cocktail combination is 2 doses of Sinovac followed by a full dose of Pfizer as a booster shot. The studies have been collected by Siriraj Clinical Research Centre in Bangkok, and directly contradicts a study at Yale University last week that said the Sinovac-Pfizer combination is less effective The study measured the Geometric Mean Titer (a titer is a lab test that measures the number of antibodies in blood), a non-linear measurement that gives a clear picture of antibody levels and vaccine effectiveness. They measured […]

Interesting study but it’s just clickbait. No mention of how many people in the study, no mention of the full morbidity and mortality rates or anything longer term. Defining “effective” by one metric is foolish. What about the effect on T-lymphocytes? Oh well as I said, Clickbait.

[Rookiescot]

Yeah I'm thinking I will go with the results published by an institute like Yale University rather than some unheard of lab in Bangkok. 

[Guest1]

 

Sinovac	Pfizer – full dose	1,143 GMT	531 GMT
AstraZeneca	Pfizer – full dose	917 GMT	531 GMT

 

And when will they have data about Sino/AZ PLUS Pfizer?

I mean, since summer, most people got just that!

And how about the 2 Sinos + 2 Astras I've got? 

[ThaiEyes]

Ah Hell, why don’t we mix them all up Sinovac, Sinopharm, AZ, Pfizer and Moderna. That’s what was available here wasn’t it

Regardless of the effectiveness of Sinovac or Astra Zeneca, it's unfortunate that the government has purchased 60 million doses of Astra Zeneca and only 30 million doses of Pfizer this year (2022).

Either way, money spent on Sinovac or Astra Zeneca appears to be money wasted not buying Pfizer or Moderna.

The old story we have made a big mistake about Sinovac . Get a  report out Sinovac is as good as all the other vaccines and tell them our Studies confirm this they will believe it.

Unlike the Yale University and Hong Kong studies which definitely tested "people", the Siriraj study may (emphasise may) not have tested "people" at all as you can get a GMT result from testing samples in a petri dish.

I'm not suggesting they did, just that it's possible to do that and the reports don't give any details.

While Moderna and Pfizer are more effective than Sinovac and AZ...

... I couldn't be happier with the Sino + AZ mix I got, why? Because I am young, and I believe Sino + AZ is more than enough which happens also to be the old school technology. No need for me to try the "new & less tested" mRNA technology. 

 

(Again not saying Moderna or Pfizer are dangerous at all, it's just I think I don't need it, and I know several people who also share this thought).

[vlad]

Thailand's PM doesn't. That's why he cancelled the last order of Sinovac due to there ineffectiveness against delta.

[Thommo]

Sounds like propaganda from you know who (CCP)

[Artemis080]

The best vaccine regime is the one you can get and better than nothing.

Having a real choice is a first world problem.

 

[palooka]

A half dose of Pfizer as a booster instead of a full dose proved to be only slightly less effective with a 1,002 GMT against Delta and a 507 GMT against Omicron.

Think this sentence says a lot for why this study was even done. 

This will justify a HALF jab of Pfizer (money saver) and at the same time say they are looking after the interests and health of Thais.

That was agonizingly sloppy at best:

Against Omicron, 2xSinovac + 1xPfizer is ...

• Siriraj study: ... more effective than is 2xAstrazeneca + 1xPfizer.
• Siriraj study: ... about as effective as is 2xSinovac + ½xPfizer.
• Yale study: ... less effective than it is against Ancestral and Delta.
• Yale study: ... more effective than are just 2 jabs (i.e. w/o booster).

There are no direct contradictions between the studies.

I understand and fully respect your point of view, @ctxa, but only up to that last point.

I know several people who are retarded so their families get a monthly allowance from the Thai government, but that doesn't mean I value their opinions!

If you want to avoid mRNA vaccines because you're unsure about the technology, but you think inactivated vaccines are sufficient for you, then great - seriously and genuinely.

It means you've looked at the available expert opinions, balanced them up, and thought your options through and made an informed choice that suits you.

The problem I have is with those who are not only misinformed but who want to misinform others - you're very much not one of those.

Not necessarily - 'anything is better than nothing' would seem to be obvious, but it's not always true.

The danger is that once vaccinated with something that you think gives you some protection you'll start to let your guard down and take more risks that affect you and others - less mask wearing, less social distancing, more socialising, etc.

Fine if it does give you more protection, but if it doesn't then you're worse off than you were before and so's everyone else.

Yet the Thai government paid for Sinovac which turned out to be the most expensive vaccine of them all. Clueless and the price of there ignorance is now  being heaped on the Thai people.

Not really, we’re people in our 20s and so we were likely to survive the disease even without a vaccine at all.

Obviously I’m not anti-vax (I’ve had 4 shots to prove it), and would happily take an mRNA vaccine if they were the only choice.

However having inactivated, and viral vector vaccines, which are proven to work, even if their effectivity is ever so slightly lesser than that of mRNA ones… I don’t see the need in my particular case for mRNA.

Sure, a Rolls Royce is the best car, but that doesn’t mean a Mercedes can’t take you wherever you wanna go. 
 

A considerable amount of people who has access to mRNA vaccines share this same thought, and I don’t see anything wrong with it. AND a huge amount of people in third world countries who have no access to mRNA vaccines because they’re the choice of the first world have to rely on inactivated ones. And inactivated ones are indirectly protecting us the first world by preventing the spread of COVID-19 in those countries.

Seriously, there’s no data at all to support that people jabbed with inactivated vaccines are more likely to spread the disease. (as you claim) You may only have a bit worse symptoms.

Which Lab in Thailand attempted to formulate there own vaccine but failed so Prayut and Co had to go begging for free donations of vaccine's from other Country's. If i remember they were given the all the ingredients to produce there A/Z Vaccine but it was too much for them and they gave up.

I've looked at all the expert opinions, not just the expert opinions of pro-vaccination proponents, and I've decided to make an informed choice which suits me. Not getting jabbed, ever.

I'm glad you've included what your problem is. I have some advice, which I posted once before, which might help you out.

 

If you are concerned about contracting "Covid-19"^TM  , which carries with it only a 99.98% survival rate, might I suggest you

1) self isolate

2) practice social distancing

3) avoid crowds

4) wear a mask

5) get vaccinated

and most especially,

6) keep your "vaccine passport" up to date by receiving your n^th booster.

Simple.

Bless - so in your readings of 'expert readings' you've managed to convince yourself that the information and advice provided by 99.99999999% of the worlds virologists and scientists can be counter balanced by some YouTube fruitcakes. I hope it goes well for you as you bask in your selfish world where consideration for your fellow being is immaterial.

Lets just hope you don't join the very very long line of committed anti vax loons that bleat to the world they wished they had been vaccinated as they pass away in a bed that could have been used for someone less selfish/stupid - I mean there have been so many they don't even make the news anymore!

No seriously I really hope you don't reach that stage ....

I could go into detail but why waste time, my comment is whhhaaaaaaaa, so funny, they expect people to believe such proppaganda nonsense.

Not enough attention, if any, to these figures was played upon. To this day, this dramatic fact and reality is ignored and certainly not marketable by them........as they have something else to sell - repeated over and again. 

The picture, not only has been missed. But deliberately removed from it's display and secretly hidden away.
