I'm genuinely interested to see the source of this slur and what evidence (proof) they have on this. Can you provide links please?

What they're going to read is scare stories on social media about blood clots

The stories about blood clots are appearing in MAINSTREAM media here in farang-land. 

[Soikhaonoiken]

AZ didn't publish anywhere near these figures when the vaccine was first produced,..&tested.. . Unless the good Doctor has had a special delivery....

Junk science.  That is a pathetic sample size which renders that "study" meaningless.  But!  Then Thailand can juke the numbers by only giving citizens one shot and then claiming Success!!!  I'd like to know who funded the study, although a uni-student could have put that size of a study together for a final's project.

No, a real media outlet.

The advice is:

1) weigh the risks of blood clots with johnson & johnson and astrazeneca VS the risks of covid

OR

2) wait for an mRNA vaccine ie Pfizer or Moderna

I do not understand why you say that. Three flights from Bangkok due in today.

We had guests arrive on Samui yesterday.

PCR test, QR code, temperature check and a form for recording health signs which is to be sent to a Line number every day.

We have more guests arriving today. They checked with the airlines and airports - same as above.

Mind you, things do change almost every day now.

Well all the flights are canceled today accept two. This was ferry passengers announced after we got back home around April 22nd.

Is this a study he has done personally? If so was the AZ from overseas? I’m guessing yes as the study took several months to complete. How does it stack up compared to overseas studies. Seems a very high result at a time when positive PR about AZ is not common. 

Don't believe the 'PR' from govts, especially EU govts'. Believe what the real experts tell you, then positive PR will be common.

"A study of 61 patients"? Sounds very scientific. 

[Trujillo]

"The DDC Director General Dr Opas Karnkawinpong says there are different goals in the vaccination program, from infection prevention, to the prevention of severe illness, and the prevention of death.

He said Sinovac’s vaccine may not have a 100% infection prevention efficacy, but the number is acceptable at more than 50%."

"The recent China’s Sinovac BioTech trial data reporting 50.4% efficiency does not “impact” Thailand’s plans to receive and administer vaccines for Covid-19 next month, according to director general of the Medical and Science Department Supakit Sirilak.

Questions have risen around the vaccine’s efficacy rate, which was originally reported as 78% in trails in Brazil, but recently downgraded to just over 50%."

So a university professor posts something on his own Facebook page (undeniably one of the premier medical resources in the world), and someone actually gives it solid credence? It's bizarre.

Thus sounds promising...but 61 people?

96.7% immunity after only one jab within a month... sorry I find that hard to believe?

If true why the need for a 2nd jab?

Hardly a significant sample size.

 

There would be much more benefit in publishing his results in a peer reviewed journal for other scientists to scrutinize.

You can't publish these results for the precise reason you stated.

[Osthos]

The statistics aside, the good Doctor brings up an interesting argument. That is the country should focus on getting as many people jabbed with the first shot, regardless of supplies for the second shot. Essentially going with the UK vaccination strategy of 12 weeks apart for each shot with the AZ vaccine. 

 

Given the success of the vaccine rollout in the UK and the clear effectiveness of their strategy, it's certainly something to consider.

You're right its something to consider when they get the supplies rolling in but thats not till around June or so.

I dont know Marty, at 100% effective against severe Covid I'd say that was quite positive PR!!!

Sinovac similarly has high efficacy against severe covid. The oftern 50% quoted is efficacy for mild disease. Efficacy drops with the severity of the disease.

They are premilinary results only. Not enough people have been vaccinated as yet, but I'm sure there will be long term studies of a larger sample. Still, these early results look promising. The lower immune response of the elderly is expected.

Doctors on the ground in India (not part of scientific studies) believe they are seeing patients who have already had 2 doses (vaccine not specified) and are requiring ICU treatment.  

I would like to see a link to that article, it's pretty significant

Maybe that's the plan, because they don't have enough vaccines. Convince everyone they only need one shot of AZ and officially reduce the dosage to one shot.

[mtls2005]

Sounds like justification for a single dose strategy?

 

Has this study been published? Peer-reviewed?

 

 

 

Sersiously, the general Thai public is being showered with quite a bit of conflicting and confusing information re: the vaccine plan. IMO, the regime would be better off being honest with the public, rather than trying to confuse them.

Here is the study just posted on his facebook page an hour ago. You can use Google to translate. 

 

Dr. Yong AstraZenica study, facebook  .

 

Here is the primary data. It is based on the seroprevalence of antibodies as someone correctly suggested above.

 

 

Seems to me that he should have tested subjects for antibodies before vaccination. Previous infection plus a single dose could produce a much higher antibody titer than 2 doses.

Excellent point.  But I think his main purpose is to counter local forces pushing Sinovac, so he posts his data on facebook, one big graph with 2  big columns. Even Anutin can see that.

Absolutely.  The man is a jackass publishing misleading information with no credibility whatsoever who would be shot down immediately in a developed country. Unfortunately Thais will readiliy believe someone like this without question.

It's okay they just set-up a "fake news committee" the PM's in trouble now.

Or at least a 12 week between doses strategy like the UK. 12 weeks increased vaccine efficacy from 76% to 82% after the second dose. [Source]

 

It would give Thailand a chance to protect the majority of its population without initially needing two doses for everyone.
