A Mix and Match approach in which a Sinovac vaccine shot is administered as the first jab, followed by AstraZeneca as the second jab yields better results against the Delta variant of the coronavirus than two doses of Sinovac, and the same efficacy as two doses of AstraZeneca with a shorter timespan, according to Thailand’s Medical Sciences Department (MSD) and Siriraj Hospital.

Make a note of this Khun Prayut:

 

Public Health England say the COVID-19 vaccine rollout is estimated to have directly averted between 91,700 and 98,700 deaths in the country

Excellent news. Seems Thailand’s strategy is a winner after all!

Another article with no study results published using a Plaque Reduction Neutralization method that does not compare results to the delta variant. 

 

Would be useful to read the actual study before. Still waiting for the last one published on a graphic and the one before published on a facebook post.

Only one problem though.

 

The authorities have cited studies into the cocktail being made by respected institutes like Chulalongkorn University, Ramathibodi Hospital and Sirirat Hospital.

The findings from more detailed studies are not due out for several months, however, according to Dr Opas Kankawinpong.

Latest situation report from WHO Thailand:

 

For 13 out of the past 16 days, (including today), the number of new laboratory-confirmed COVID-19 cases has exceeded 20,000. Although the number of severe cases reported today (5,439) has decreased, the number of ventilated cases (1,168) is the 3rd highest reported and the number of deaths is the 2nd highest (301), following the reporting yesterday of 312 deaths. Healthcare facilities will continue to see a very high burden of COVID-19 cases in the coming days and weeks, and the number of reported deaths is expected to remain high.

Most people dying of COVID-19 are unvaccinated, or received only one dose of vaccine. A briefing was also provided by the Ministry of Public Health on the 18th August, which included information on the record number of deaths reported that day. Of the 312 fatalities reported, the vaccination status was known for 180 individuals. Of these 180 people, 147 had not received any vaccination and 33 had received only one dose of vaccine. Out of theses 180 individuals, there were none who had received two doses of vaccine. The remaining 132 cases are waiting for verification of information on vaccination status.

Vaccination rates in the elderly in Thailand are not high enough
The graph below shows the percentage of the elderly who have received either one or two doses of COVID-19 vaccine in the 29 provinces designated as maximum/strict control areas. The milestone set in Thailand is to achieve 70% coverage. Although Bangkok has already reached 90% coverage of the 1st dose, the next highest coverage rates are just 56% in Pathum Thani and 50% in Samut Sakhon.

Further - with similar conclusions, here is an article on a separate study (still ongoing I believe) that has similar conclusions:

https://mgronline.com/qol/detail/9640000072391

The article is in Thai language, but one can use the Chrome browser to translate 'on the fly'.   It has an interesting chart that shows the antibody counts (where the Pfizer column should be ignored due to insufficient data).  The timing of the data collected, suggests that a significant portion of the tests were done when the delta variant was present.

The tests in that study as the one before are just to measure antibody levels not effectiveness from any particular strain. Tests for effectiveness with delta are a separate matter and need separate longterm study results.

 

There's a thread on the study you refer to here

Phuket Update;

 

129 new community cases, 2 new cases from sandbox, no new deaths. 77 new cases from rapid tests have not been included.

From everything I've read from the scientific circles, antibody levels alone don't entirely equate to a vaccine's effectiveness in preventing symptomatic infection or worse outcomes like hospitalization or death.

 

The means by which the various vaccines combat the COVID virus are more complicated and involved than just antibody measurements, or at least, that's what the scientists outside Thailand seem to be saying.

 

"The recent NYU study, which has not yet been peer-reviewed, focuses on antibody measurements (in a lab setting), but that’s just one of many aspects of the immune system that contribute to protection against Covid, according to Shane Crotty, professor at the La Jolla Institute for Immunology who studies how the immune system remembers infections and vaccines.

 

“Your immune system is complicated, and doesn’t just have one weapon,” Crotty says. “You’ve got neutralizing antibodies, other kinds of antibodies, you’ve got memory B cells and T cells.”

 

Think of your immune system like a football team, Crotty suggests. “If you were just paying attention to the wide receivers’ statistics, those are useful numbers, but you’re missing all the things that the other teammates are doing that are actually influencing the outcome,” he says.

Thanks.

 

Unfortunately that thread provides no real information on the study.  I prefer the Thai language link I provided, which has plots of anti-body levels from the ongoing data collection.

It's well known that vaccine antibodies aren't the primary key to immunity.  We don't carry antibodies to many childhood diseases, but we do keep the immunity.   From we know, some times protection lasts a lifetime, sometimes several years and sometimes a year or so.
