Virus expert reveals why Thailand chose AstraZeneca’s viral vector vaccine


webfact

Recommended Posts

What this expert has not said is that the Chinese Vaccine is far more expensive as it is supplied on a with profit basis and probably with strings attached whereas the AZ vaccine is being supplied on a without profit basis whilst the pandemic persists also it is easy to handle and it will be manufactured in Thailand under license thanks to the UK Government

Math is not Dr Yong's strong point.

 

It's a matter of what assumptions are being used. Vaccinating 4 billion people with 8 billion doses is correct math, if the goal of health authorities is to get immunity in 50% of the population, on the assumption the virus will die out with herd immunity after that. Although if the Astra Zeneca vaccine is only 70% effective, the math gets wonky again.

Well, have a look to this nice article of yesterday:

 

https://www.wionews.com/india-news/goodwill-gesture-india-begins-export-of-coronavirus-vaccines-to-six-nations-357837

 

Myanmar, Bangladesh, Afghanistan, Bhutan, Nepal, the Maldives and the Seychelles will start to vaccinate their people very soon. With the Astra Zeneca vaccine, produced under licence in India. All these countries will start to vaccinate and to protect their citizens long before Thailand will start.

 

Thailand number one again. This time number one in possibly willingly delaying the vaccination, for ridiculous and hypocritical reasons, for omission of ordering the vaccines early enough.

 

Move to India then and you won;t have to complain about things

So is Thailand going to manufacture their own vaccines?  India is already way ahead.

Try keeping up with the News.  Thailand will son start manufacturing the AZ vaccine.

 

So what if India is ahead?  They have multiples more infected and dieing.  Thailand is doing pretty well all things considered.  But if you don;t like it I;m sure you have the abiity to go to India and live there.

Or perhaps he is making allowance for the fact that not 100% of all doses manufactured will be used to vaccinate...some will go for QC testing, some will get spilt, some lost, some spoiled. 

 

But such considerations would not fit the anti-Thai knee jerk reaction of some.

So will the Johnson & Johnson Jansen version, but it will be one dose. Should be available in 1-2 months.

 

I think the AZ and JJ vaccine (if it works) could be used as one dose vaccines, nevertheless 2 doses will be necessary to ensure long term immunity.

 

The Pfizer vaccine really does need to be used as stated by the drug company. 

 

I suspect all the vaccines will be less effective than quoted at preventing mild infection, but prove to be very effective at preventing serious illness.  Fair play to Oxford for consistently stating its vaccine is not designed to prevent infection.

Thailand should be positioning itself for the J&J right now. Simply stands to reason that a single shot will be easier to administer as well as get people to take than some two shot vaccine that people might not be motivated to get the second shot later on.

They stated that their clinical trials so far have not measured for that, but they are optimistic that there will be such an effect. It stands to reason that there will be, we just don't yet know how much.

Mr Yong explained. “The global population is more than 7 billion. Just 50 per cent of population would need 8 billion vaccines since each person has to take two doses. So it will be impossible to vaccinate everybody within this year.”

 

Maybe maths aint his strong point. 7 Billion vacines not 8 Billion...

 

Yeah, these guys are so used to "adding" a little extra on top...

 

If you had read the statement carefully with respect to "each person has to take two doses, then his math is correct. 2 X 7 billion = 14 billion ==> 8 billion divided by 14 billion = 0.5714  ==> converted to a percentage 57.14% ==> As he states that there are "more than 7 billion" people in the world  his estimate of "just 50%" is in the ballpark.

He didn't even say what stage of approval they're in for the AZ, nor how long before they pull the trigger.  Doesn't instill too much confidence in the future.

Its not been submitted for approval yet as far as I know. It will be produced by Siam Bio Science here in Thailand, the technology transfer has happened but the actual production is still underway in testing format, Astra Zeneca are carrying out the quality control to ensure its produced and replicated 100% correctly, this stage is not over yet.

 

Questioning the progress or lack of is also not wise considering who owns Siam Bio Science

Another reason why Oxford vaccine (perhaps others) was so quick and also effective is it has basically been in development for years (possible decade(s)) for such a scenario. It's not a last minute, rush to get it out thing. 

I wasn't aware that Covid had been around for decades

It is already being discussed in Big Pharma, that a 3rd shot may be necessary. If that is really necessary to obtain immunity, or if it is just to gain more profit is unknown.

It is a normal discussion one can have with every vaccination: a certain percentage only needs 1 shot while your coverage will increase with 2 or more shots. Basically they are weighting the risk and cost of ever more shots against the chance of reaching herd immunity the quickest and cheapest way possible. Once herd immunity has been reached it all stops mattering as the virus will barely spread anymore from then onwards. 

If more people refuse to take the shots it will mean the ones who do take it will need a higher % of immunity reactions so a 3rd shot might be needed to reach herd immunity (or people refusing to take the shots need to be convinced better).

Looks like Astra Zeneca will be the first before the Chinese one.

 

"The AstraZeneca vaccine developed with Oxford University and approved for use in the United Kingdom and United States is expected to win FDA authorization for emergency as early as this week.

 

Top FDA official Surachok Tangwiwat said the doses now under consideration have been manufactured by other countries. He did not specify which country was selling unused doses, how many were being imported, or their cost to taxpayers. Authorization is pending some additional documentation, he added. The approval could accelerate manufacture of the vaccine in Thailand by Siam Bioscience, a new pharma player owned by the palace."

Maybe Dr. Yong is smart enough to allow for wastage. There is bound to be some.

Maths isn't a strong point here

 

The global population is more than 7 billion. Just 50 per cent of population would need 8 billion vaccines since each person has to take two doses

 

50% of 7 billion x2 is 7 billion. 

 

still beats me why they are chasing the Chinese vaccine?
