Two doses of Sinovac can stop spread of COVID-19 – National Vaccine Institute

[snoop1130]

About 95% of those who have received two doses of the Sinovac vaccine have developed an immune response which prevents the spread of SARS-CoV-2, or COVID-19, according to research jointly conducted by the Thai Red Cross Emerging Infectious Diseases Health Science Centre of King Chulalongkorn Memorial Hospital and the US Armed Forces Research Institute of Medical Science (USAMD-AFRIMS).

 

The National Vaccine Institute said that 186 volunteers have joined the clinical trials, to test their immune response to the SARS-CoV-2 virus. All of them had received their second dose of Sinovac vaccine at least two before the trial.

 

Blood samples were drawn and tested with the live virus two weeks after the second dose and the result shows that more than 70% of the 171 volunteers had developed an immune response strong enough to prevent the spread of the virus in laboratory tests.

Good to hear this, and to see that it was a joint US-Thai effort that produced these results.

 

Hopefully this will help reassure some of those of those on the fence to get vaccinated! ????‍⚕️

[Petey11]

Good news yet they keep talking 70% first vaccination for opening up???

[ThaiFelix]

Oh no this cant be correct.....its made by the baddies!!??

[ikke1959]

there is a need of more vaccine to vaccinate. From March to now only about 3 million with 2 jabs and 5,5 million with 1 jab. With 90 million jabs to go = 95: 4 months passed = almost 24 months to go before 70% has got 2 jabs.... a lot can happen in .the meanwhile

A recent study done in Hong Kong doesn't really advocate Sinovac ...  Especially when the Delta variant Covid-19 virus is present.

https://www.thaienquirer.com/28831/delta-variants-danger-and-new-studies-raises-questions-about-thai-vaccine-program/

 

But the application of the Sinovac vaccine is problematic. Emerging data shows that the current vaccines, especially the ones with lower efficacy rates like the Sinovac, are not effective in stopping the transmission of the Delta variant.

 

Even a leading Thai Dr. proposed farangs entering the Phuket sandbox with Sinovac vaccination should not be let into the sandbox.  (Yet, a large number of people in Phuket were vaccinated with Sinovac by Thai Gov.)

There is a BIG difference between saying 95% of people developing an immune response and saying what the headline says, "Two doses of Sinovac can stop spread of COVID-19".  The latter simply isn't supported by ANY evidence, including the "evidence" in this so-called study.

 

The article starts with this (hopefully true) great news...

No, no, no, no, no.   An immune response on a petri dish does NOT mean a vaccinated person can't still catch the virus and transmit it to others!

 

The sentence concludes by attributing the claim...

Well, we don't have a link to any data. 

 

Well, there are no links to the study's findings and no links to any data.  We don't know how or what they actually tested.  We don't know anything about the study except for what the author of this piece wrote.  And the article doesn't even have an author named, so there's no way to find out if the author even has a basic understanding of the science.

 

Basically the article is worthless, though the study may not be.  We just don't know what the study actually says.

 

If anyone finds a link to it, I hope you'll post it here.

AZ vaccine efficacy against variants is around 60 percent with two shots.  

What does this mean for that stuff coming out of China who's efficacy is only 51 percent with two shots?  I bet it's not 51 percent, and certainly not 70 percent.

The biggest issue with Sinovac is that there is a dearth of published data regarding large scale, highly controlled testing of the sort that western FDA's require to approve vaccines. Only bits and pieces of data from small scale tests.

 

Which naturally raises suspicion about the reason for the lack of data.

This was not a real world study to test effectiveness against actual transmission but only to test immune reaction and response. It also does not mention which variant this study tested which is just as important.

If it was published that the Chinese gunk is near useless against the Delta variant and Thais were being injected by the government with a vaccine that may not work it may upset the locals ! a bit.

I just received an email from the Canadian Embassy about easing border measures, and they mentioned that Canada doesn't recognize Sinovac and won't except that people to forgo 14 day quarantine upon arrivial. These are the requirements, at least for Canadians. The accepted vaccines are:

• Pfizer (Comirnaty, tozinameran, BNT162b2)

• Moderna (mRNA-1273)

• AstraZeneca (Vaxzevria, AZD1222, Covishield)

• Janssen (Johnson & Johnson) - single dose

So I am going to have to wait, don't know how long for Moderna or AZ.

 

Dear Canadians,

You are receiving this email because you are registered with the Government of Canada's Registration of Canadians Abroad service.

On June 21^st, 2021 the Government of Canada announced the extension of some of Canada’s border measures as well as some changes to current measures that will begin to ease some testing and quarantine requirements for fully vaccinated travellers who are currently permitted to enter Canada.

Easing of border measures

Beginning July 5, 2021 at 11:59 p.m. EDT, fully vaccinated travellers will not be required to quarantine or complete a day-8 test. In addition, fully vaccinated travellers arriving by air will not be required to stay at a government-authorized hotel to await their on-arrival test result.

Unvaccinated minors or dependent adults who are travelling with fully vaccinated travellers must still quarantine for 14 days and follow all testing requirements, but are not required to stay at a government-authorized hotel.

To be eligible for these exemptions, fully vaccinated travellers must still meet the pre-entry and on-arrival testing requirements, be asymptomatic and submit all required COVID-19 information electronically into ArriveCAN prior to travel to Canada, have a paper or digital copy of their proof of vaccination, and have a suitable quarantine plan.

Fully-vaccinated travellers

To be considered fully vaccinated, travellers must have received the full series of a COVID-19 vaccine — or combination of vaccines — accepted by the Government of Canada, at least 14 days prior to entering Canada. Currently, those vaccines are manufactured by Pfizer, Moderna, AstraZeneca/COVISHIELD, and Janssen (Johnson & Johnson). Travellers must provide proof of vaccination in English or French (or a certified translation).

You will find below the list of accepted and not accepted vaccines at the moment. We recommend that you visit the section entitled Determine if you’re fully vaccinated regularly as the list of accepted vaccines may expand in the future.

Accepted vaccines:

• Pfizer (Comirnaty, tozinameran, BNT162b2)

• Moderna (mRNA-1273)

• AstraZeneca (Vaxzevria, AZD1222, Covishield)

• Janssen (Johnson & Johnson) - single dose

Vaccines not currently accepted for fully vaccinated status in Canada:

• Bharat Biotech (Covaxin, BBV152 A, B, C)

• Cansino (Convidecia, Ad5-nCoV)

• Gamalaya (Sputnik V, Gam-Covid-Vac)

• Sinopharm (BBIBP-CorV, Sinopharm-Wuhan)

• Sinovac (CoronaVac, PiCoVacc)

• Vector Institute (EpiVacCorona)

• Other

Travellers can receive their vaccine in any country but must provide a certified translation confirming their vaccination status if proof of vaccination is not provided in English or French.

The Government of Canada will accept translations that were produced by a certified translator whose certification can be confirmed by a stamp or membership number with a professional translation association. 

Eligibility

Only those travellers who are currently eligible to enter Canada and are now fully vaccinated, are eligible for these new measures if they meet specific criteria and requirements. Specific questions regarding quarantine measures can be directed to the Public Health Agency of Canada https://health.canada.ca/en/public-health/corporate/contact-us.html.

Only individuals with a right of entry (Canadian citizens, permanent residents and persons registered under the Indian Act), as well as some foreign nationals who are not prohibited from entering Canada under the Orders in Council (Prohibition of Entry into Canada from the United States; Prohibition of Entry into Canada from any Country other than the United States) can currently enter Canada.

Individuals can verify if they are allowed to enter Canada. 

Not fully-vaccinated travellers

There are no changes to Canada’s current border measures for travellers who are not fully vaccinated. Travellers must continue to adhere to the current testing and federal 14-day quarantine requirements, and provide COVID-19-related information electronically through ArriveCAN before arriving in Canada. Unvaccinated and partially vaccinated air travellers must also book a three-night stay at a government-authorized hotel before their departure to Canada.

Persons who have recovered from COVID-19 can continue to test positive long after they have recovered and are no longer infectious.  Travellers who have previously tested positive for COVID-19 must provide proof of a positive COVID-19 molecular test conducted between 14 and 90 days prior to their scheduled flight.

IMHO its simply a response to quell the headlines recently.

Where was this conducted? WHO has peer reviewed?

As others point out. What variants?

It's a very disingenuous headline.  Like saying.....

 

           "New cancer treatment shows 100% success rate in large scale study"

 

Then you start to read and in the fifth paragraph it says.....

 

           Dr. Pat McGroin, lead researcher of the study conducted on mice, could

           point the way to treatment in the battle against cancer.  "It might take

           us 40 or 50 years, but the results are exciting!"

I agree it's misleading and most of what I read in the media I think is misleading especially during this pandemic.

Congratulations would be a good idea to publish details of the trials and conclusions as this will be really good news.

[malibukid]

the Sinovac is not as effective as the J&J, Moderna against the emerging variants.  3 shots of the Sinovac vaccine would be required to match the efficacy of the Moderna and or the J&J. also Sinovac is not officially accepted for vaccinated travel into most countries with the exception of China.  but its your body.

Somebody is telling a lie. First off the efficacy for Sinovac is less than 46% WITH TWO SHOTS! Ask those in Indonesia and look even closer at BKK which is having a surge.  Second, where did you come up with this info Thai Visa? You aren’t helping your country by encouraging them to get a substandard vaccine.

That also seems to mean 70% of Thai's so Samui will open with about 40% vaccinated if you include foreigners who will not be vaccinated before re-opening.
