Several factors make Thais vulnerable to Omicron variant infection

Don't they all reduce the symptoms an thus reduce the risk of hospitalization? That is there primary effect. 

 Mitigating symptoms makes them a therapy, not a vaccine. Several people I know who got ‘boosted’ then got covid shortly after.

A recent HongKong study revealed that zero antibodies were found by Sinovac after the booster against Omicron. Google and you’ll find. Zero! Maybe that‘s the main issue for Thailand in the near future? Good that Omicron is more focusing on the bronchi. So just take m-rna as third or fourth shot in 2022. Good luck to the people.

Since vaccines work by priming the immune system to quickly attack any incoming virus, no vaccine, for any disease, totally prevents infection (as defined as the pathogen entering the body).  What they do is greatly shorten the duration and severity of infection - often (but not always) to such an extent that there is no clinical indication of the disease at all.

 

This is not considered "mitigation" it is considered prevention. Prevention of disease not prevention of infection.

 

Measures like masks, isolation, hand washing etc are measures for prevention of infection.

 Actually it means more than that. It means particles less than 50 micrometers in diameter which  can stay airborne for an extended period of time.

 

Aerosolized transmission is same as what is referred to as airborne transmission.

 

Droplets refer to particles that are heavier than air so do nto remain in the air long *but can be picked up from touching contaminated surfaces).

 

In terms of masks, cloth mask would likely suffice for droplet spread but not for aerosolized (though still better than nothing).

 

I'm flying back to Thailand Sunday and planning to double or triple mask (surgical masks) at the airport(s), on the flight (it is short flight from Cambodia so heavy masking should be possible without fainting!) and on check-in/check out at the T&G hotel.  Once out I will stay home until after the day 5-6 PCR -- easily done. 

 

Not because I fear Omicron in terms of my health - I am quadruple vaxxed (2 AZ in Thailand, 2 Pfizer in US, and last dose just 3 months ago) but because I really, really do not want to end up forcibly hospitalized so worry about test results.

 

 

If you are looking for surgical masks to protect you, you should try to acquire the equivalent of N95ish masks (N I think is an American classification, KF94 masks from Korea are also a good mask to get) and a face shield (that is what my sister wears when she has to fly - diplomat). Surgical mask is more about preventing an asymptomatic person from spreading the disease (in close quarters especially), outside the sun will disinfect surfaces better and outdoors is better as well for air circulation which in combination with the sun -- does a fairly good job... as long as you maintain the 2 metres or so should reduce the risk for outdoors.

 Yes, vaccines do that, but mRNA gene therapies are not vaccines. Persons who have been vaccinated for measles, polio, yellow fever or anything else do not catch and transmit those illnesses as easily as an unvaxxed person, nor do those real vaccines wear off after just a few months.

  Also, vaccinated people typically make up about 80% of covid hospital cases, so there is no symptom reduction at all.

 

1. mRNA vaccines ARE vaccines. Definition of vaccine = a preparation that is administered to stimulate the body's immune response against a specific infectious agent or disease. There are several different types of such preparations, of which the mRNA vaccines are one, viral vectors are another, inactivated viruses are another etc etc. All are vaccines.

 

2. mRNA vaccines are NOT gene therapies. Gene therapy is defined as treatment which permanently alters the genetic makeup of body cells, usually  to replace defective genes cause genetic disorders. mRNA vaccines do not enter the cell nucleus  and do nto in anyway alter the genetic code of the person vaccinated.

 

3. Completely untrue that majority of hospitalized COVID cases are vaccinated, the opposite is very much the case.

Chilean study shows variations in success of COVID-19 vaccines

Chile began one of the world's fastest inoculation campaigns against COVID-19 in December, having now fully vaccinated more than 60% of its population, predominantly with Sinovac's (SVA.O)CoronaVac.

That vaccine was 86% effective in preventing hospitalization, 89.7% effective in preventing admission to intensive care units and 86% effective in preventing deaths within the population between February and July, health official Dr Rafael Araos said in a press conference on Tuesday.

Hello Ms. Sheryl -- Maybe you haven't seen my posts but I was on the the ThaiSmile flight we46 SAT DEC 11 that brought the 2 Thai citizens returning from Belgium BKK to Khon Kaen who then became the patient-zeroes of the the Kalasin Omicron cluster.

 

I got a NOT/DETECTED/NEGATIVE PCR test 2 weeks later 25 DEC and, as far as reporting goes, no one else on the flight was infected. I don't know where the two Thais sat either in the boarding lounge or on the plane but on an Airbus 320 it's hard to be too far away from anyone.

BTW I wear a KN95 mask while on the plane.

You are confusing death after vaccination with death caused by vaccination.

 

As for comparison to other vaccines: most are given to children whereas most COVID vaccination has been of adults, with proportionately higher coverage in the elderly.  Naturally more will die after a COVID vaccination that after a childhood vaccination.

 

After, not due to.

To take last things first, that's a report about antibody response.

So far as I can tell, there have been no studies done about how well it perfroms against serious illness and death from Omicron. Although, it may be that Omicron doesn't pose much of a threat of serious illlness or death compared to previous variants.

What you fail to grasp is that VAERS stands for Vaccine Adverse Event Reporting System. Not the Vaccine Adverse Effect Reporting System. Here's an explanation from the CDC:

 

"VAERS accepts reports of adverse events and reactions that occur following vaccination. Healthcare providers, vaccine manufacturers, and the public can submit reports to the system. While very important in monitoring vaccine safety, VAERS reports alone cannot be used to determine if a vaccine caused or contributed to an adverse event or illness. The reports may contain information that is incomplete, inaccurate, coincidental, or unverifiable. In large part, reports to VAERS are voluntary, which means they are subject to biases."

Warning: This link is not part of the official VAERS adverse events reporting system, the CDC, or any other official organization.  It is a private vaccine septic website that arranges partial information in a way to spread vaccine fear. They leave out critical information, particularly relative reporting rates which increased under COVID.  WIKI:

 

"During the COVID-19 pandemic, raw VAERS data has often been disseminated by anti-vaccine groups in order to justify misinformation and safety claims related to COVID-19 vaccines, including adverse reactions and fatalities claimed to have been caused by vaccines. Websites such as Medalerts (published by the anti-vaccine group National Vaccine Information Center) and OpenVAERS (which published a tally of vaccine adverse events and fatalities allegedly linked to COVID-19 vaccines based on VAERS data), have been linked to this misinformation. Comparative studies of VAERS, which look at relative reporting rates, have found that the data does not support these claims."

I think that after mRNA vaccines received EUA the US should have used wartime powers (as was done with ventilators) to build more production capacity for these vaccines so that by now, at least, urban areas of the world could be fully vaccinated. Then the issue would have been a moot point. As it was, many countries were between a rock and a hard place. The advice to take any vaccine was not a solution to this pandemic.

They forget one thing !!  The crappy vaccines used in Thailand.. 

Bad news for China and many countries in Asia. The vaccine against Corona from Sinovac does not work at all against Omikron. The Chinese vaccine fails to produce antibodies that attack this mutation of the virus. This is shown by a large test in Hong Kong. According to the scientists behind this study, Pfizer is also moderately effective against Omikron. Only 25 percent of people injected with this substance have antibodies against the Omikron mutation. But that is still more than at Sinovac, where zero antibodies were found. Sinovac has been widely deployed in China to combat the pandemic. Also Turkey, Pakistan, Thailand, the Philippines, Hungary and Brazil mainly use this vaccine. It is not in use in the Netherlands. The study, conducted by the University of Hong Kong, will concern these countries. Especially because it appears that the vaccine also shows worse results against the beta mutation of the virus than Western vaccines. With that, many vaccination campaigns would now be almost useless. Sinovac uses a dead virus to train human defenses. Pfizer uses mRNA technology, which provides immunity against a small part of the virus.

The vaccine is mostly useless and its use is not recommended by professionals.

There are labs testing the procedures for human nasal vaccines.

 

[Dirk Z]

My educated guess is the opposite. Maybe Omikron will not overwhelm Thailand:

1. Already a large part of the population is vaccinated. True, some with less effective vaccines but still even they offer some protection.

2. Like in the first wave: Thailand has a young population, not much overweight, not that much smoking, at least among women almost 0%

3. I believe many Thai have been infected with Covid without having many symptoms or such light symptoms that they were not tested, scared to be put in a field hospital for two weeks. So they developed an immunity.

4. Corona viruses have been present in this part of the world for tens of thousands of years. There must be some adaptation in the immune system which makes it different from for instance Europeans.

5. Whatever you read here: Thai are very aware of infectious diseases, they have been around forever and they adapt their lifestyle to deal with it. So if news comes of an outbreak the frist thing most do is stay home, the best response.

A three-dose course of the Pfizer or Moderna mRNA vaccines is said to be 10 times more effective than a three-dose course of AstraZeneca, but three months after inoculation, he said that the efficiency of Pfizer or Moderna vaccine will drop by about 40%, citing a study by Pfizer.
