Thailand Launches Major Dengue Vaccine Trial in Children

Thailand is taking a significant step in combatting dengue fever by initiating a large-scale clinical trial for a new vaccine targeting children. Set to commence on April 4 in Nakhon Phanom province, the trial involves 35,000 children aged seven to ten, regardless of prior exposure to dengue.

 

Endorsed by the National Communicable Disease Committee, this study seeks to evaluate the vaccine's effectiveness, with hopes of integrating it into Thailand's universal healthcare system upon completion. Director General of the Department of Disease Control, Dr Panumas Yanawetsakul, revealed that the testing is expected to conclude in three years, paving the way for the vaccine's inclusion in the healthcare programme.

 

Developed by a Japanese pharmaceutical company, the vaccine is a live-attenuated type, similar to the measles vaccine and already registered with the Thai FDA. Although promising, Dr Nakorn Premsri, leader of the National Vaccine Institute, cautions that its integration into the national healthcare scheme will require careful review, weighing the test results against cost-effectiveness.

 

 

While dengue vaccines are currently available in Thailand, they are primarily offered by private healthcare providers at significant cost. This government initiative aims to make dengue immunisation accessible and affordable to millions.

 

Endemic in over 100 countries, dengue fever remains a major health concern, especially in tropical areas like Thailand. The vaccine trial, therefore, is a critical effort to reduce infections and lessen the strain on the healthcare system. With Thailand reporting thousands of cases yearly, health experts are hopeful that a successful trial will lead to widespread immunisation, ultimately saving numerous lives.

 

The government is dedicated to monitoring the trial's progress and ensuring that, if successful, the vaccine quickly becomes part of public healthcare, reported The Thaiger.

It's not in the 'off the beaten track' section. But I'll risk posting.

 

All I can say is; ''poor kids.''

Why worry? According to you, viruses don't exist.

They don't; but those filthy jabs do.

 

The OP mentioned 'measles'. Just to point out that measles was fatal for 1 in 500,000, before the jab was introduced into the US. Pretty soon after, that ratio went to 1 in 10,000. Now it's even less. The UK's NHS say measles kills one in 100.

 

Hello!! Any white-coats listening?

And no mention of "safety" precautions in the report above just money and that it "will save numerous lives" as if its a forgone conclusion.

They should be mindful of what has happened with live attenuated Polio vaccines.

Polio is still endemic in Afghanistan.

 

The country has one of the highest infant mortality rates in the world. Ignorant mullahs are mainly responsible for vaccine resistance.

 

The only notable  side effect I seem to have from my multiple vaccinations is a low tolerance of fools.

...regardless of prior exposure to dengue?  You gotta be kidding?
That's irresponsible.  Antibody Dependent Enhancement affecting those who previously had Dengue are a dangerous and documented issue with of Dengue vaccines. It's also why as second infection of Dengue can kill you.  I hope they don't end up killing some of these children.  These kids need to be carefully screened prior to receiving the vaccine.  But it sounds like they are going to go "full speed ahead and damn the torpedoes."  So what if they kill some of the children of the peasant class.
Good lord.

Antibody-Dependent Enhancement: A Challenge for Developing a Safe Dengue Vaccine
"For the enhanced vaccine safety, all dengue vaccine candidates should be assessed for the extent of type-specific (minimal ADE) vs. cross-reactive (ADE promoting) neutralizing antibodies. The type-specific EDIII antibodies may be more directly related to protection from disease in the absence of ADE promoted by the cross-reactive antibodies."

I've no idea about the technicalities of the study. How many will get the real thing, and how many will receive a placebo. Will the kids past medical history be considered. Etc.

 

I think the outcome will be a lot of kids getting sick. And!! An outbreak of Dengue Fever in the province later this year. Just as the wet season gets underway. Then the call will go out; get the kids vaccinated.

The article didn't mention the brand - but clearly the study refers to the QDenga Vaccine marketed by a Japanese pharma. It's already approved by the Thai FDA as mentioned, and is also approved the European Medicines Agency - EMA (the EU's FDA) and other countries.

 

It's easily available at private hospitals here, so I don't think there's anything to worry about for the kids. It's approved for anyone 4 years of age and above by the EMA - no upper age limit for Europe. In Thailand they stick to 4 - 60 years of age. (The only reason 60 is the upper age limit is due to an abundance of caution recommended by the manufacturer as QDenga's trials didn't involve anyone older than that).

 

It's two shots/jabs spaced over 3 months. It isn't cheap though, as mentioned. So I'm not really sure what this Thai 'vaccine trial' is all about. How would reproducing the Qdenga Japanese trials on kids 7 - 10 make it any cheaper for Thailand? It seems an odd thing to do (unless they don't trust the original trials by the manufacturer). Regarding older people, the Japanese trials focused only on mere hundreds, compared to many thousands of younger kids, who are more vulnerable to dengue (by being outdoors more than older working-age people).

I've got it backwards.  If you've had Dengue that vaccine is recommended up to 60.  The ADE risk comes from vaccinating someone who never had Dengue and then contracts Dengue after the vaccination.  I looked into this a few years back and now remember that I was over the age limit but having had Dengue before, fit that checkbox.

Too bad they didn't provide the vaccine's name and manufacturer.  I'd be interested in knowing what it is.  Still - if they are vaccination all these kids without addressing ADE reactions - well, my humble opinion - it borders on criminal. No doubt the parents will be told it's 100% safe and to sign the liability waivers ("don't bother to read them") providing the researchers and vaccine manufacturer with indemnity.
