Does Sinovac Booster Offer 94% Protection Against Omicron?

Does Sinovac Booster Offer 94% Protection Against Omicron?

Does the Sinovac booster dose really offer 94% protection against the Omicron variant?

Let’s take a look at their claim, and find out what the facts really are!

 

Sinovac : Booster Dose 94% Protective Against Omicron!

On 15 December 2021, Sinovac claimed that three doses of their CoronaVac vaccine had a 94% neutralising antibody rate against the Omicron variant.

This was not an official announcement posted on their website, but announced through Global Times, a Chinese state media outlet.

The latest study shows three shots of Chinese biotech firm Sinovac’s inactivated vaccine can lead to a 94 percent neutralizing antibody rate against the Omicron variant, while the rate after two shots is 35 percent, the Global Times learned from the company on Wednesday.

The study was conducted by the company on 20 people who received two shots and another 48 who received three shots. Seven in the first group and 45 in the second tested positive in neutralizing antibodies against the Omicron variant, the company said in a statement to the Global Times.

Sinovac said that the data demonstrated that the administration of a booster shot of its vaccine can effectively enhance the vaccine’s neutralizing capacity to the Omicron variant, read the statement.

 

Does Sinovac Booster Offer 94% Protection Against Omicron?

Unfortunately, it does not appear that the Sinovac booster shot actually offers 94% protection against the Omicron variant.

And here are the reasons why…

Fact #1 : Sinovac Did Not Post Official Statement / Study

Most of the press blindly posted Sinovac’s claims, without bothering to fact check.

I refrained from commenting earlier, because I was waiting for Sinovac to actually post their study details, or at least an official statement.

However, it is now 1 January 2022, and Sinovac has posted neither the study results, nor an official press statement.

In case you are wondering if Sinovac actually posts such press releases, yes, they do. On 9 September 2021, they posted a press release announcing that a third dose of their vaccine is able to “effectively neutralise the SARS-CoV-2 variants of concern“.

Fact #2 : Sinovac Results Were Misleadingly Worded

If you read the Global Times report very carefully, you will notice that it was carefully worded to say one thing, but imply something else altogether.

In that report, Sinovac claimed a 94% neutralising antibody rate against the Omicron variant, suggesting that their booster dose offers 94% protection against Omicron. That is not what it actually means.

Sinovac stated that they detected neutralising antibodies against Omicron in 45 out of 48 people (93.75%) who received three doses of their vaccine, but cleverly avoided mentioning :

  • how much neutralising antibodies were present (the Geometric Mean Titre),
  • whether the quantity of neutralising antibodies was high enough to protect against Omicron, and
  • whether the 45 individuals with neutralising antibodies were able to avoid getting infected by the Omicron variant.

So while they may have detected neutralising antibodies against the Omicron variant, that does not mean that the antibodies were present in high enough quantities to deliver adequate protection.

The results certainly do NOT mean that the Sinovac booster dose is capable of offering 94% protection against the Omicron variant.

Fact #3 : Sinovac Booster Dose Proven To Be Ineffective Against Omicron

The University of Hong Kong and the Chinese University of Hong Kong recently conducted a study of the Pfizer and Sinovac booster dose.

In that study, they found that three doses of the Sinovac vaccine boosted neutralising antibodies against Omicron, compared to just two doses.

However, the amount of neutralising antibodies produced by three Sinovac doses was much TOO LOW to protect against the Omicron variant.

In fact, the three Sinovac doses were only able to deliver the equivalent antibody titre of two Pfizer doses against the Omicron variant.

Fact #4 : Sinovac Did Not Prove Booster Dose Protects Against Omicron

Sinovac is technically correct in claiming that the booster dose enhances protection. That’s what ALL booster doses do – they enhance protection.

However, unless they share their actual study data (particularly the antibody titre), they cannot claim their booster dose effectively protects against the Omicron variant. They offered NO EVIDENCE to prove that.

On the other hand, the recent HKU and CU study has shown that the increased antibody levels from the Sinovac booster dose is not enough to protect against the Omicron variant.

It is past time to stop using the Sinovac vaccine. It was the least efficacious COVID-19 vaccine to be approved, and it does not get much better with a third dose.

The Omicron variant is proving to be highly infectious, and those who were received the Sinovac vaccine will need to get a Pfizer booster dose to obtain sufficient protection.

If you were fully-vaccinated with the Sinovac vaccine, please opt for a Pfizer booster dose. Don’t waste your time with a third dose of the Sinovac vaccine.

Pfizer vs. Sinovac : Which Is Better Against Omicron Variant?

Which works better against the Omicron variant – Pfizer COMIRNATY, or Sinovac CoronaVac?

Let’s find out what the two latest studies have shown!

 

Pfizer vs. Sinovac : Which Is Better Against Omicron Variant?

Everyone is worried about the new Omicron variant of COVID-19 because it has been proven to have greater ability to breakthrough vaccine protection, far more than the Delta variant!

This is not just a concern for the low-efficacy Sinovac CoronaVac vaccine, it is also a big concern for the Pfizer COMIRNATY vaccine.

So just how effective are both vaccines against the Omicron variant? Let’s find out…

If you just want the TLDR summary, here it is :

  • Two doses of the Pfizer vaccine will only protect 20% to 24% of fully-vaccinated individuals against Omicron.
  • Three doses of the Pfizer vaccine offers very good protection against the Omicron variant.
  • Even three (booster) doses of the Sinovac vaccine do not offer protection against Omicron.
  • A Pfizer booster dose offers good protection against Omicron, for individuals vaccinated with two doses of the Sinovac vaccine.

The studies show that three doses of the Pfizer vaccine are required to adequately protect against the Omicron variant, while those vaccinated with the Sinovac vaccine should opt for the Pfizer booster dose.

For those who want the details, please continue to the next section…

 

Pfizer vs. Sinovac Efficacy Against Omicron : 2 Doses

A recent Hong Kong University (HKU) study showed that the Omicron variant has significant vaccine escape capability in fully-vaccinated individuals.

  • Pfizer vaccine antibodies were able to bind to the Omicron variant only in 20% to 24% of individuals.
  • Sinovac vaccine antibodies were completely unable to bind to the Omicron variants.

The results suggest that mutations in its spike protein are allowing the Omicron variant to significantly block most Pfizer vaccine antibodies, and all Sinovac vaccine antibodies.

While the Pfizer vaccine will continue to offer protection to 20% to 24% of fully-vaccinated individuals, the Sinovac vaccine offers no protection at all.

The Geometric Mean Titre (GMT) results in this study also suggest that a third (booster) dose will boost the Pfizer vaccine’s neutralising antibody response against the Omicron variant.

On the other hand, the HKU study authors concluded that “whether a third dose of the present CoronaVac vaccine will enhance the neutralising antibody response against the Omicron variant remains to be determined.

COVID-19

Seropositive Rate MN Titer (GMT)
Pfizer Sinovac Pfizer Sinovac
HKU691 Omicron 20% 0% 5.43 Min.
HKU344-R346K
Omicron
24% 0% 6.42 Min.
Delta 100% 68% 124.7 10.3
Beta 100% 0% 25.7 Min.
Alpha 100% 100% 229.4 21.7

 

Pfizer vs. Sinovac Efficacy Against Omicron : Booster Dose

Sinovac claimed on 15 December 2021, that three doses of their CoronaVac vaccine had a 94% neutralising antibody rate against the Omicron variant. However, they did not share the study, or even publish an official press release.

Fortunately, the medicine faculties of Hong Kong University (HKUMed) and the Chinese University of Hong Kong (CU Medicine) conducted a study of the Pfizer and Sinovac booster dose.

Here is a summary of their key findings :

  • Two doses of Pfizer or Sinovac vaccines do not provide sufficient protection against the Omicron variant.
  • Three doses of the Pfizer vaccine offers the highest level of protection against Omicron.
  • A Pfizer booster dose given to those who received two Sinovac vaccine doses obtain good protective antibody levels against Omicron.
  • Three doses of the Sinovac vaccine do not provide sufficient protection against the Omicron variant.
  • Antibody levels of three doses of the Sinovac vaccine were roughly equal to two doses of the Pfizer vaccine.

 

Pfizer vs. Sinovac Efficacy Against Omicron : What Should You Do?

The two studies from Hong Kong should serve as a sober warning for those vaccinated with the Sinovac vaccine.

The Sinovac CoronaVac vaccine has always the least efficacious COVID-19 vaccine approved – just 50.4% effective in preventing symptomatic infection by the original SARS-CoV-2 virus.

Its efficacy has further suffered against the Delta variant and the Gamma variant, but it continued to be used because there was insufficient supply of better vaccines and it still offered good protection against hospitalisation and death.

But now that these studies have shown that neither two nor three doses of the Sinovac vaccine will offer any protection against Omicron, it’s time to stop using the Sinovac vaccine.

It’s time to acknowledge what many scientists and doctors have long known – that the Sinovac vaccine was a stop-gap solution, until there was sufficient supplies of better vaccines.

We now have adequate supplies of better vaccines. There is NO REASON to continue using the Sinovac vaccine.

If you were fully-vaccinated with the Sinovac vaccine, please heed these results and opt for a Pfizer booster dose, as recommended by many health authorities.

Pfizer / Sinovac vs. Omicron : What HKU Study Just Revealed!

How well do the Pfizer and Sinovac vaccines work against the Omicron variant? Not very well, I’m afraid.

Take a look at what a small HKU study just revealed!

 

Pfizer / Sinovac vs. Omicron : How Was HKU Study Conducted?

The University of Hong Kong recently conducted a small lab study to investigate how well the Pfizer and Sinovac vaccines work against the new Omicron variant of COVID-19.

Before I go into the study results, it is important that you understand how they conducted their study. You can also read their preprint.

The HKU team took blood samples from two groups of people who received their first dose 56 days earlier :

  • 25 people who received two doses of the Pfizer-BioNTech COMIRNATY vaccine
  • 25 people who received two doses of the Sinovac CoronaVac vaccine

They removed all cells and clotting factors from the blood samples, to derive the serum which would contain neutralising antibodies.

The HKU team then used the 50 serum samples to assess their ability to neutralise :

  • Omicron variant from South Africa (HKU691)
  • Omicron variant from Nigeria with additional R346K mutation (HKU344-R346K)
  • Alpha, Beta and Delta variants (as controls)

They basically mixed the serum with the virus sample for an hour, and then added the mixture to a Vero cell culture for 3 days, before examining them to see if the cells were infected and destroyed.

 

Pfizer / Sinovac vs. Omicron : What HKU Study Just Revealed!

The problem with most of the reporting I’ve read is that – the writers did not actually read the preprint, only the HKU press release.

Not only did they miss a ton of details, they also missed some important points. So let me start by first summarising what the HKU team found in this table :

COVID-19
Variant
Seropositive Rate MN Titer (GMT)
Pfizer Sinovac Pfizer Sinovac
HKU691 Omicron 20% 0% 5.43 Min.
HKU344-R346K
Omicron
24% 0% 6.42 Min.
Delta 100% 68% 124.7 10.3
Beta 100% 0% 25.7 Min.
Alpha 100% 100% 229.4 21.7

Also, take a look at the geometric mean titre (GMT) of Microneutralisation (MN) antibodies provided by the HKU team :

So what does this HKU study tell us? Let me summarise the key takeaway points :

Pfizer-BioNTech COMIRNATY Vaccine

  1. Pfizer vaccine antibodies were able to bind to the Omicron variant in 20% to 24% of samples.
  2. Pfizer vaccine antibodies were able to bind to Alpha, Beta and Delta variants in 100% of samples.
  3. Pfizer neutralisation antibody titres were highest against Alpha and Delta variants.

The results suggest that mutations in its spike protein are allowing the Omicron variant to significantly block Pfizer vaccine antibodies.

There is some protection from the Pfizer vaccine antibodies, but a third dose is necessary to boost the neutralising antibody response against the Omicron variant.

The good news is that the study shows that the Pfizer vaccine is excellent at neutralising the Alpha and Delta variants.

Sinovac CoronaVac Vaccine

  1. Sinovac vaccine antibodies were completely unable to bind to both Omicron variants, as well as the Beta variant.
  2. Sinovac vaccine antibodies were able to bind to 100% of the Alpha variant samples, but only 68% of the Delta variant samples.
  3. Sinovac neutralisation antibody titres were highest against Alpha and Delta variants, but were 10.5X to 12X lower than the Pfizer titres respectively.

The results suggest that the Omicron variant can completely evade neutralising antibodies produced by the Sinovac vaccine.

That’s why the HKU study authors concluded that “whether a third dose of the present CoronaVac vaccine will enhance the neutralising antibody response against the Omicron variant remains to be determined.

The results also confirm yet again that the Sinovac CoronaVac vaccine is far less efficacious than the Pfizer-BioNTech COMIRNATY vaccine across the board.

CAVEATS

As interesting as the HKU study results are, there are a few caveats we should be aware of :

  1. This is a very small study
  2. This is an in vitro (laboratory) study, and not a real world study
  3. It only assessed neutralising antibodies in the serum, and does not assess T cell immunity

 

Pfizer / Sinovac vs. Omicron Results : What Should You Do?

For scientists, these alarming results suggest a need for the COVID-19 vaccines to be tweaked or updated to cover the Omicron variant.

For the rest of us, it means we need to take a booster dose as soon as we are able to. The HKU team ended their study with the same advice :

[B]efore the availability of these next generation vaccines, booster doses of currently available vaccines will likely render most people having protective levels of neutralizing antibody titers.

But it is also not just getting a third dose, but a booster dose of a better vaccine. This is especially important if you earlier received a less efficacious COVID-19 vaccine like the Sinovac CoronaVac.

Those who had earlier received the Sinovac vaccine should heed these results, and opt for a Pfizer or Moderna booster dose, as recommended by many health authorities.

New Measures To Block Omicron Variant From Malaysia!

With the Omicron variant rapidly spreading across the globe, Malaysia has initiated new measures to block it from reaching our shores.

Here is what you need to know…

 

New Measures To Block Omicron Variant From Malaysia!

On 1 December 2021, the Malaysia Minister of Health Khairy Jamaluddin announced a series of new measures to block the Omicron variant from reaching our shores.

This decision came after 20 countries reported over 200 cases of the Omicron variant of COVID-19 :

Country Omicron
Cases
Country Omicron
Cases
South Africa 128 Austria 4
Botswana 19 Brazil 2
Portugal 13 Canada 2
The Netherlands 12 Japan 2
United Kingdom 9 Denmark 2
Australia 6 Spain 1
Hong Kong 5 Reunion Island (France) 1
Germany 5 Belgium 1
Italy 4 Czech Republic 1
Israel 4 Sweden 1

 

How Malaysia Intends To To Block Omicron Variant!

Temporary Travel Ban

Malaysia will no longer allow flights from or transiting through countries with Omicron variant transmission, or high risk countries, will be blocked.

These are the eight (8) countries that the Malaysia Ministry of Health (KKM) has listed under the travel ban :

  • South Africa
  • Botswana
  • Eswatini
  • Lesotho
  • Mozambique
  • Namibia
  • Zimbabwe
  • Malawi

There is also a temporary travel ban for non-Malaysian citizens from those countries, including travellers who have been in those countries during the last 14 days prior to arrival.

Malaysian citizens and holders of long-term passes (PR status, spouse visa, MM2H and resident pass) are still ALLOWED to return to Malaysia, subject to these restrictions :

  • Irrespective of their vaccination status, they must undergo a 14-day mandatory quarantine at a quarantine station.
  • They must undergo three RT-PCR COVID-19 tests :
    – within 72 hours before departure,
    – on arrival in Malaysia, and
    – on the 10th day of the mandatory quarantine
  • A risk assessment will be conducted on the 14th day of quarantine, which may be extended if the traveller is symptomatic.

Malaysian citizens who are planning to visit the listed countries are NOT ALLOWED to continue with their travel plans.

Vaccinated Travel Lane

Arrangements to create a Vaccinated Travel Lane (VTL) with countries with Omicron variant transmission, or high risk countries, have been postponed.

In addition, the Malaysia-Singapore VTL programme for both air and land travel has been amended to require travellers to undergo additional COVID-19 self-tests on the 3rd and 7th day after arrival.

They must then report their test results in MySejahtera.

Monitoring Of Countries With Omicron Variant Cases

The Ministry of Health (KKM) will monitor and provide the other government ministries with a DAILY LIST of countries with Omicron variant cases, or at high risk.

Strengthening Of International Gateways

The Immigration Department of Malaysia has immediately STOPPED the use of the Autogate system.

Flights carrying passengers from the listed countries with Omicron variant transmission, or high risk countries, are only allowed to enter Malaysia through KLIA.

Airlines are responsible for identifying passengers travelling from countries with Omicron variant transmission, or high-risk countries. This information must be submitted to the KLIA Health Office for easier handling of the arrivals.

MAHB is required to create a special “gate” and path for travellers from countries with Omicron variant transmission, or high-risk countries, to undergo a health screening before undergoing their special quarantine.

International Students + Foreign Workers

International students and foreign workers from countries with Omicron variant cases, or high-risk countries, will be temporarily BANNED from entering Malaysia.

Langkawi International Tourism Bubble

Tourists from countries with Omicron variant transmission, or high-risk countries; or those with history of travel to those countries in the past 14 days, are NOT ALLOWED to participate in the Langkawi International Tourism Bubble.

Malaysian citizens (Langkawi residents) returning from countries with Omicron variant transmission, or high-risk countries, are ALLOWED to return to Malaysia, but only through KLIA and must undergo a mandatory 14-day quarantine in a special quarantine station.

Foreign tourists who are confirmed to be positive with the Omicron variant of COVID-19 will be isolated and treated in a private hospital, at their own cost.

China’s Guidelines For Sinovac Vaccine : The Facts!

We checked out the claims, and here is the sweet and short verdict – this is yet another piece of FAKE NEWS.

For those who want to understand more, here are the FACTS :

Fact #1 : Beijing Vaccine Prevention Center Does Not Exist

The Chinese term actually translates to Beijing Epidemic Prevention Center, which makes far more sense than a Vaccine Prevention Center.

But either way – there is no such institution called the Beijing Vaccine Prevention Center or the Beijing Epidemic Prevention Center (北京市防疫中心).

The closest candidate is the Beijing Center of Vaccine Clinical Evaluation (北京疫苗临床评价中心).

Fact #2 : Vaccine Guidelines Were Issued By China’s National Health Commission

On 29 March 2021, China’s health authorities issued their first official COVID-19 vaccination guidelines.

But they were not issued by some Beijing institute, but China’s National Health Commission.

Fact #3 : The Real Vaccine Guidelines Contradicts Fake List

Here is a summary of the key vaccine guidelines issued by the National Health Commission.

  • The four conditionally approved vaccines are safe for senior citizens aged 60 and above
  • Senior citizens aged 60 and above should get vaccinated
  • Booster shots are not recommended at this stage.
  • It is not recommended for those under the age of 18 to get vaccinated for now.
  • Vaccination should be completed using the same vaccine, and not mixed.
  • Under special circumstances, people can use a mix of vaccines to complete their vaccination.

They completely contradict the fake list that is circulating on WhatsApp and Facebook.

Photo Credit : News.cn

Fact #4 : Hong Kong Guidelines Contradict Fake List

The Hong Kong government noted in their 19 February 2021 interim recommendations on the Sinovac COVID-19 vaccine that the only risk to look out for is an allergic reaction.

Allergic reactions may occur after administration of CoronaVac. Recipients of CoronaVac should be kept for observation and monitored for a minimum of 30 minutes.

Persons with a history of allergies should consult your doctor or pharmacist for advice before you receive this vaccine.

A second dose of the vaccine should not be given to those who have experienced an allergic reaction to the first dose of CoronaVac.

Fact #5 : Official Sinovac Guidelines Contradict Fake List

The Hong Kong government also provided the Sinovac CoronaVac vaccine’s package insert, whose list of contraindications contradict the fake list above :

  • People with history of allergic reaction to CoronaVac or other inactivated vaccine, or any component of CoronaVac (active or inactive ingredients, or any material used in the process).
  • Previous severe allergic reactions to the vaccine (e.g. acute anaphylaxis, angioedema, dyspnea, etc.)
  • People with severe neurological conditions (e.g. transverse myelitis, Guillain-Barre syndrome, demyelinating diseases, etc.)
  • Patients with uncontrolled severe chronic diseases;
  • Pregnant and lactating women.

It also lists conditions in which the vaccine should be administered with caution :

  • People aged 60 years and above (which China’s National Health Commission just approved – see Fact #3)
  • People with acute diseases, acute exacerbation of chronic diseases, severe chronic diseases, atopy and fever.
  • People with diabetes, history of convulsions, epilepsy, encephalopathy or mental illness, or with family history of such diseases.
  • People with thrombocytopenia or hemorrhagic diseases – the injection may cause bleeding.
  • People with impaired immune function, such as malignant tumour, nephrotic syndrome, AIDS.
  • People who require human immunoglobulin injection – there should be at least one month interval before vaccine administration.

KKM Did Not Warn That Vaccine Reduces Immunity?

Did KKM fail to warn people that the COVID-19 vaccine reduces immunity, letting them fall sick or dying?

Take a look at the latest viral warning, and find out what the FACTS really are!

 

Claim : KKM Should Warn That Vaccine Reduces Immunity

This viral message is being shared on WhatsApp, warning that KKM should warn people that the COVID-19 vaccine reduces their body’s immune system for 46 days, putting them at risk of falling sick or dying!

It’s a very long message, so skip to the next section for the facts…

KKM gives No clear guidance to people receiving the vaccines. So, this is very vital info for staying alive after the jab!
🟥🟨🟥

All who are vaccinated MUST READ!

To the editors-in-chief of Sin Chew Daily, China Daily and Oriental Daily:

Lately, many who are vaccinated have also contracted Covid-19 and died, among whom are middle-aged and elderly. According to report received, the dead were infected within one and a half months after the vaccination! 🟨🟥

I know that when we are vaccinated, our immunity becomes lower than before. Therefore, the chance of contracting Covid-19 is higher. However, most people lack this knowledge. After being vaccinated, they think they don’t need to wear masks, wash hands or disinfect. They would go to the market and walk around. As a result, they fall sick!

 

Truth : COVID-19 Vaccine Does NOT Reduce Immunity!

Like 95% of viral messages on COVID-19 – this is yet another piece of FAKE NEWS based on some facts.

Let me go through the claims and share with you what the FACTS really are. Please share this with your family and friends!

Fact #1 : COVID-19 Vaccine Does NOT Reduce Immunity

Let me be very clear – the COVID-19 vaccine does NOT reduce immunity.

The COVID-19 vaccine is nothing more than a self-defence class for your immune system, teaching it how to fight against the real SARS-CoV-2 virus.

Will learning self-defence in real life make you a weaker person? Of course, not!

The COVID-19 vaccine does not reduce your natural immunity one bit, not even for one day.

As your immune system learns to make antibodies against these antigens, it grows stronger, not weaker, against COVID-19.

Fact #2 : Side Effects Are Signs Of Immune Response

Just like how you sweat and get muscle ache in a self-defence class, you may feel a little sick after your vaccination.

That is not evidence that the COVID-19 vaccine has reduced your body’s immunity. That is your body’s natural reaction when your immune system gets triggered by the vaccine.

The fever that you may get, for example, is a way for your body to boost its immune response. So when you get a fever, your body actually produces a more robust immune response, not weaker.

Fact #3 : Full Immunity Takes Time

It is true that maximum immunity takes time – often two weeks after the second dose is taken (for a 2-dose vaccine).

The second dose is designed to kick the immune system into high gear, basically telling it – “Warning, this is not a one-time attack! COVID-19 can come again!

This not only triggers the immune system to create more antibodies, it also activates your memory cells to “remember” SARS-COV-2 for faster recognition and antibody production in the future.

That is why it is important to complete both doses of a 2-dose vaccine, and continue to practice COVID-19 precautions until your body has enough time to build its defences.

Fact #4 : It Does Not Take 3 Months To Improve Immunity

Dr. Zhong Nanshan – China’s top respiratory disease physician – never claimed that it will take up to 3 months to build the body’s immunity after COVID-19 vaccination.

On 1 April 2021, he told Hong Kong’s Phoenix TV that COVID-19 vaccines using the inactivated virus technology – like Sinovac and Sinopharm – usually takes 40 days to trigger enough antibodies to prevent infection.

Not only is 40 days not 3 months, his comments were regarding inactivate virus vaccines, not mRNA vaccines like Pfizer or Moderna, or viral vector vaccines like AstraZeneca.

Fact #5 : You Can Get Infected After Vaccination

It is true that you can get infected with COVID-19 even after completing your vaccination. However, that is not because COVID-19 vaccines reduce your immunity.

These vaccine breakthrough infections are expected, because vaccines cannot guarantee complete protection.

Even the best COVID-19 vaccines – from Pfizer and Moderna – can only prevent 94%-95% of COVID-19 infections. That means 5% of those who are fully vaccinated using these vaccines could still get infected.

That does not mean vaccines are useless. COVID-19 vaccines are not meant to prevent all infections. They are meant to prevent SEVERE DISEASE and DEATH!

If you get infected with COVID-19 after vaccination, you will likely get a mild disease, or it may even be asymptomatic!

Fact #6 : We Must Maintain COVID-19 Precautions After Vaccination

Vaccine breakthrough infections can be greatly reduced once herd immunity is established.

In addition, vaccinated people who get mild or asymptomatic COVID-19 infections can still spread COVID-19 to other people.

So we must CONTINUE to take COVID-19 precautions, even after we are fully vaccinated.

This will help protect both the unvaccinated from getting infected, and the vaccinated from breakthrough infections.

Malaysian Vaccination Certificate Rejected By Hong Kong?

Is the vaccination certificate of Malaysian travellers being rejected by Hong Kong authorities?

Take a look at the new viral warning, and find out what the FACTS really are!

 

Malaysian Vaccination Certificate Rejected By Hong Kong?

On 22 July 2021, this warning about the Malaysian vaccination certificate being rejected by Hong Kong authorities went viral.

Wah, our digital Vac certificate is not recognised by HK!! I thought there should be global reciprocity!

[22/7, 7:30 pm] HS: News travels fast.
Hong Kong health ministry has declared the following this morning:

1) Malaysia is now classified as one of the highest risk countries for COVID-19 infection

2) All returning Hong Kong residents from Malaysia will need to undergo a 21 days compulsory quarantine at a designated hotel and to undergo 4 specific COVID-19 test, upon arrival, on the 5th day, 10th day and 18th day

3) Vaccination certificates issued by the Malaysian authorities will not be recognised or accepted and a new COVID-19 vaccination has to be administered locally

What a shame to Malaysian!!
[22/7, 7:30 pm] HS: Our digital certificate not laku!!!

 

Fact : Malaysian Vaccination Certificate NOT Rejected By Hong Kong

This is yet another piece of FAKE NEWS being created every day and shared on WhatsApp. Here are the FACTS…

Fact #1 : Hong Kong Does Not Have A Health Ministry

Hong Kong is a Special Administrative Region in the People’s Republic of China.

It does not have a Health Ministry, only a Department of Health, which reports to the Hong Kong Food and Health Bureau.

Fact #2 : Hong Kong Did Not Declare Malaysia As Highest Risk Country

The Hong Kong government did not classify Malaysia as “one of the highest risk countries for COVID-19”.

The HK Department of Health issued two press releases on 22 July 2021, both not related to Malaysia. Neither were there any press statements about Malaysia in the last month or so.

The HK Immigration Department has not issued any press releases since 19 July 2021, certainly nothing about Malaysia in the last month or so.

Fact #3 : Malaysia Still Classified As Group B Country

As of 22 July 2021, Malaysia is still classified as a Group B country by the Hong Kong government, which is the third rung of their risk ladder :

  • Group A1 (Extremely High Risk) : Brazil, India, Indonesia, Nepal, Pakistan, The Philippines, South Africa and The United Kingdom.
  • Group A2 (Very High Risk) : Ireland, Russia
  • Group B (High Risk) : Argentina, Bangladesh, Belgium, Cambodia, Canada, Colombia, Ecuador, Egypt, Ethiopia, France, Germany, Italy, Japan, Kazakhstan, Kenya, Korea, Malaysia, the Netherlands, Romania, Singapore, Switzerland, Thailand, Turkey, Ukraine, the United Arab Emirates, the United States of America, and Vietnam
  • Group C (Medium Risk) : All other countries, except China and those not in Groups A1, A2, B and D.
  • Group D (Low Risk) : Australia and New Zealand

Fact #4 : Non Residents Are Barred From Entering Hong Kong

As of 22 July 2021, the Hong Kong government bars non-residents from entering Hong Kong if they have stayed in these countries in the last 14 days :

  • Taiwan
  • Any country in Groups A1, A2, B and C

That practically means that non-Hong Kong residents must first stay in a Group D country – either Australia or New Zealand – for at least 14 days before they are allowed to enter Hong Kong!.

Fact #5 : Hong Kong Recognises Many COVID-19 Vaccines

As of 29 June 2021, the Hong Kong government recognises thirteen COVID-19 vaccines, including the three vaccines being used in Malaysia – Pfizer, AstraZeneca and Sinovac.

Fact #6 : Everyone Entering Hong Kong Must Quarantine

Whether you are vaccinated or not, all travellers – whether Hong Kong residents or foreigners – must quarantine after entering Hong Kong.

As mentioned above, only non-Hong Kong residents travelling from Group D countries (currently Australia and New Zealand) are allowed to enter Hong Kong.

  • If fully vaccinated with recognised vaccines :
    – 7-day compulsory quarantine in a designated quarantine hotel
    – 2 tests during quarantine
    – 3rd test on 12th day
  • If not fully vaccinated / vaccinated with unrecognised vaccines :
    – 14-day compulsory quarantine in a designated quarantine hotel
    – 3 tests during quarantine
    – additional tests on 16th and 19th days

Fact #7 : Everyone Entering Hong Kong Must Undergo A COVID-19 Test

Irrespective of whether you have been tested before flying to Hong Kong, all travellers to Hong Kong are required (as of 22 July 2021) to undergo a COVID-19 test on arrival.

Testing is conducted at the HK Department of Health’s Temporary Specimen Collection Centre, and travellers have to wait for their test results.

Only after a negative test result are they permitted to travel to their quarantine hotel.

Those who test positive will be transferred to a hospital for isolation and treatment.

Fact Check : Rev. Patrick Mahoney Hypocrisy On Protests

You have probably seen the Spot The Difference post criticising Rev. Patrick Mahoney on his hypocrisy on the Hong Kong and George Floyd protests.

Find out if it’s true that Patrick Mahoney posted those tweets on the Hong Kong and George Floyd protests!

 

Spot The Difference : Patrick Mahoney Hypocrisy On HK + George Floyd Protests

Controversial Christian pastor Rev. Patrick Mahoney waded into the Hong Kong and George Floyd protests, with two tweets on the same day.

The next day, this post started going viral on Twitter, Facebook and WhatsApp, asking you to spot the difference between the two Patrick Mahoney tweets.

Note : The original post lacks the two MISLEADING warnings, which we added to avoid further abuse.

 

Rev. Patrick Mahoney Hypocrisy On Protests : True But Misleading

Here is our short TLDR summary for those who just want to know the facts :

  • he posted those two tweets, and yes, they are partly hypocritical
  • however, the Spot The Difference post misused one photo and is intentionally misleading,
  • Patrick Mahoney did not actually sanction violence in the Hong Kong protest

Patrick Mahoney is just a self-aggrandising Christian pastor with a history of publicity stunts – a nobody.

Unfortunately, his two tweets are being misused by Chinese and pro-Chinese netizens (and bots) to spread the narrative of American hypocrisy.

Ironically, this misleading Spot The Difference post is being shared on Twitter, Facebook and WhatsApp – platforms which are banned in China. That is really the true hypocrisy of this storm in a teacup.

 

Rev. Patrick Mahoney Hypocrisy On Protests : The Facts

And for those who want to know more, here are the facts :

Fact #1 : Patrick Mahoney Posted Those Two Tweets

Reverend Patrick Mahoney sure posted those two tweets, on the same day – May 28, 2020.

Fact #2 : Patrick Mahoney Did Not Sanction Violence

As his actual tweet on the Hong Kong protest above shows – he did not actually sanction violence.

In fact, his actual tweet on the George Floyd protest in Minneapolis could be referring to violence by both the police and the protestors.

We would rate his posts as partly hypocritical, because he wasn’t against the George Floyd protests, just against the violence.

Fact #3 : The Protestor Picture Was From 2016

The Spot The Difference post creator intentionally replaced the picture Patrick Mahoney posted with this Getty photo that Lam Yik Fei took on the night of 9 February 2016.

As you can see, it’s radically different – showing violence – whereas the picture Mahoney posted showed Hong Kong police officers arresting non-violent protestors.

Fact #4 : Injustice Started Both Protests

Discounting the violence, both Hong Kong and George Floyd protests started because of injustice. In both cases, the people are demanding change.

The people in Hong Kong have been protesting for years over the systematic erosion of their Basic Rights and freedoms.

The most recent May 2020 protest was triggered by the proposal of new national security laws that would allow Chinese security forces to operate within Hong Kong.

In the United States, it was the racism that black Americans have endured, triggered by the death of George Floyd after a white police officer kneeled on his neck for almost 9 minutes.

Fact #5 : Protests Are Allowed In The US And Hong Kong

The First Amendment of the United States Constitution specifically gives all American citizens have the right to assemble and demonstrate peacefully :

Congress shall make no law … abiding … the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.

Unlike China, Hong Kong citizens have the right to peacefully assemble and protest under Article 27 of the Basic Law, and Article 17 of the Bill of Rights.

The right of peaceful assembly shall be recognised. No restrictions may be placed on the exercise of this right other than those imposed in conformity with the law and which are necessary in a democratic society in the interests of national security or public safety, public order, the protection of public health or morals or the protection of the rights and freedoms of others.

In other words – people have the right to assemble and demonstrate in both the United States and Hong Kong. They just do not have the right to attack people, or destroy property.

Fact #6 : Patrick Mahoney Is Not The American Government / People

Patrick Mahoney is a self-aggrandising Christian pastor with a history of publicity stunts. But in the grand scheme of things – he is nobody.

He is not a representative of the American people, or the American government. Yet, his two tweets are being misused by Chinese and pro-Chinese netizens (and bots) to spread the narrative of American hypocrisy.

Ironically, this misleading Spot The Difference post is being shared on Twitter, Facebook and WhatsApp – platforms which are banned in China. That is really the true hypocrisy of this storm in a teacup.
