More than 15 million doses of vaccine done - Sinovac efficacy against Alpha 90%, says official

[Lemonltr]

Laboratory studies vary so much that they are suspect for accuracy. By far the most reliable is that which comes from hospital data in countries with many months of vaccinations. 

Currently I'm in the UK which has 100% delta. 

Our Health Minister has covid (2 x AZ jabs) Local to me a close relative age 27 poorly at home with covid. A lady poorly also plus her friend very ill in hospital. All 3 jabbed twice with Pfizer. 

Most tragic of all a neighbour's anti vaccer son 45 died leaving a wife and two children.

Yes, I read that and thought immediately the medical authorities do not wish to divulge the truth . 

I think there is obviously concern over people not wanting to take vaccines. Both sinovac and AZ have their detractors. For that matter, Pfizer and Moderna worry some people in countries where it is available.

 

so It’s understandable that the Thai authorities wish to try and give reassurance about the vaccines they have available. It’s just that they lack so much credibility by virtue of being caught lying on issues related to Covid, that people think twice about believing them.

 

and this type of article that is meant to give reassurance, actually does the opposite for me because it doesn’t address the most pressing issue. It goes over old ground.

The defense machine is ramping up!  There were three articles in the local Post today.  One defending Anutin, one defending Prayut and one by a WHO official defending Thailand's response to the pandemic saying that the problem is that Thailand was blindsided by the variants.  I wonder what the government's vaccination plan was.   We waited many long months for the availability of the AstraZeneca Vaccine and then the Moderna Vaccine.   With a supply of three million doses of AZ per month, did the government plan to take 23 months to give its 70 million inhabitants their first shot?  If second shots were given during this time, then the number of first shots possible would have halved.  Then the order of five million Moderna shots for the private hospitals was constantly delayed.  What exactly was the government's vaccination plan?  Was there any thought-out plan?

Among the viruses that have become endemic in humans, some have also figured out ways to dodge the adaptive immune system: H.I.V.-1 mutates rapidly; herpes viruses deploy proteins that can trap and incapacitate antibodies.

Thankfully, SARS-CoV-2 does not seem to have evolved any such tricks yet — suggesting that we still have an opportunity to stem its spread and the pandemic by pursuing a relatively straightforward vaccine approach.

"that Sinovac was 90% efficacious in this regard against the Alpha variant."

 

Thats that then, although its only 50.4 efficacious against the Alpha variant.

 

The problem that we're trying to fight against the Delta variant.

A vaccine you don't have is 0% effective against delta or any other variant.

I tell you what this sort of article does and no doubt this is in the Thai media. What it does is gives the whole population (except the lap dogs and gullible) a good old laugh how everyday these morons just downright lie and expect people to believe them. These empty heads live and function in a complete different reality to the people they are trying to con. It will not work. Like the biggest empty head trying to blame the spread of this virus on the people. It's an absolute disgrace.

I would not expect other vaccines faring any better with Delta than Pfizer, and data being any better than one coming from single vaccine mass vaccinated Israel. And from their data, Pfizer is 39% effective against Delta.

 

• Israeli Health Ministry says Pfizer vaccine is effective against COVID-19 dropped to just 39 percent in Israel.
• The continued decline in efficiency coincides with the outbreak of the virus. mutant Delta species in the country
• Israel vaccination against COVID-19 The first dose is given to more than 5.75 million people, or 61.6 percent of the population.

https://www.timesofisrael.com/israeli-uk-data-offer-mixed-signals-on-vaccines-potency-against-delta-strain/

 

"The Israeli statistics also appeared to paint a picture of protection that gets weaker as months pass after vaccination, due to fading immunity. People vaccinated in January were said to have just 16% protection against infection now, while in those vaccinated in April, effectiveness was at 75%."

 

Down to 16% after 6 months...looks like boosters (more than one) are on the horizon. Interesting whether they'll put a time limit on vaccination certificates. This could create issues for people jabbed in their home country, if a booster shot is not available here.

 

Australia just announced it purchased 85 million Pfizer vaccines for booster shots 2022-2023. The population is around 25 million..that's a lot of boosters!

Delta variant is the most dangerous version of COVID-19 currently and causing the most infections.

 

Here is some of the latest findings about vaccine efficacy against Delta:

https://observer.com/2021/07/covid19-vaccine-efficacy-delta-variant-studies-pfizer-moderna-oxford/

 

Studies have mixed results. Here are a few details from the article:

- Pfizer/BioNTech, Moderna and Oxford/AstraZeneca—provides “considerable protection” against the delta variant

 - one dose of the Pfizer/BioNTech vaccine was 56 % effective against symptomatic infection; Moderna 72 %; Oxford/AstraZeneca 67 %, but these results have NOT been peer reviewed.

- one dose against Delta variant efficacy - Pfizer/BioNTech 36 percent; Oxford/AstraZeneca 30%

- Pfizer/BioNTech vaccine just 36-39 % in preventing infections caused by the delta variant, maybe 2 dose recipients, article doesn't specify.

Looks like the Delta Variant ( B.1.617.2) has muted in India. See here:

Looks like more bad news is coming.

Delta is causing 85% of infections in USA. One study says, Delta variant has about 1,000 times more viral particles in respiratory tracts compared to Alpha strain. Hospitalization risk after infection with Delta is about 85% higher than with Alpha

Delta variant is a variant of Sars-Cov-2 not Covid-19. Covid-19 is the resulting disease. As for vaccines mRNA appears to be better but time from innoculation, how many you have had and potential new variants are in the mix. One problem I have is the global focus is keeping up with the virus. I hope there is still a thorough investigation how this ever mutating virus came to be. For those who say this is zootic never before has a virus evolved and mutated so rapidly from nature. I may be wrong of course and welcome any direction to peer reviewed articles to state otherwise. Sorry @banana7 for getting a bit side tracked on my reply. The world is in the s*** and we need to know why.

One of the main reasons that the virus has mutated so much is that it is very contagious. The more humans who get infected the more opportunity there is for mutations to occur.

[newnative]

   Uh, oh.  Studies against Delta are 'ongoing'.  So, lead with the good news that it works well with what we no longer have and hopefully they'll soon forget about asking how the Delta data is looking . . .

Well, in the case of AstraZeneca it's not about effectiveness. This is from the BBC article you linked to:

"Australian doctors have reported a surge in the number of people cancelling their vaccine appointments, amid a new wave of caution over the AstraZeneca jab.

It comes after the government updated guidance last week to recommend only those aged over 60 get the shot, due to the risk of a rare blood-clotting syndrome."

Under-60s have been advised to get the alternative Pfizer shot, of which there are limited supplies.

Also, the duration of infection is important. Covid infections tend to last a long time.

But how effective against all other current variants is more important now they are appearing in Thailand.

From the information l have, testing done in other parts of the world shows that Pfizer is 95% effective followed by Moderna 94% then Sputnik at 92%. Astra Zeneca is 70% J and J 66% and Sinovac a lowly 50%. You can derive you own decision from that info.

More nonsense. There is a range of effectiveness for each of the vaccines depending on the study. The latest effectiveness result for Pfizer came in at 39%, And as epidemiologists point out, there are lots of factors that make it hard to compare the results from one study to the other. Which variant was prevalent, the composition of the cohort, etc.

What's more, there seems to be some kind of mental block in lots of people in understanding what effectiveness means in these tests. In regards to Covid it typically has meant how effective the vaccine is in suppressing any symptoms and or infections. It does not measure how potent the vaccine is in preventing symptoms serious enough to require hospitalizations and in preventing deaths. Always the percentages are higher for preventing hospitalizations and deaths. Why is that so hard to understand?
