Human trials of Thailand’s Covid-19 vaccine to begin next month

Thailand’s Health Minister, Anutin Charnvirakul, says the first stage of human trials of a locally-produced vaccine will get underway next month. The jab is a joint collaboration between the Government Pharmaceutical Organisation and the Faculty of Tropical Medicine of Mahidol University. It’s understood the vaccine has performed satisfactorily in animal testing, showing an ability to stimulate immunity.

Pannee Pitisutthitgan from the Tropical Medicine Department says human trials will take place in 3 stages. Phase 1 will involve 210 volunteers and will be conducted over 2 months, to determine the ideal dosage. In phase 2, researchers will trial 2 of the most effective dosages on 250 participants, with the aim of gaining enough data to move to phase 3 by the end of 2021.

Once the vaccine has successfully completed all 3 phases, the vaccine manufacturers will seek approval from the Food and Drug Administration and, once that has been granted, the jab will go into production locally.

According to a Thai PBS World report, Kiatipoom Wongrachit from the Public Health Ministry, says the GPO is very experienced in the production of flu vaccines and is collaborating with Mahidol University’s Faculty of Tropical Medicine, with support from the US-based Program for Appropriate Technology in Health.

Meanwhile, Veerapong Poomirattanaprapin, from the Faculty of Tropical Medicine, says his department has more than 30 years’ experience in testing various vaccines, including those used against bird flu, dengue fever, cervical cancer, HIV, and the seasonal flu. He adds that the Thai volunteers in next month’s trials will be either given the vaccine or a placebo. Those who show positive results will also take part in phase 2 trials.

      So if after those tests they can say the vaccin works. No Covid found on the testpersons. Bring it on the market.

    Good point, can they even run a phase 3 in Thailand? Wouldn’t they have to do it in another country?

      Exactly. 🙂

      The chances of catching the virus are, fortunately, so slim here that any Ph 3 test would be meaningless – or Ph 1 or 2, for that matter.

      Even more so when (if?) there’s a vaccine roll out.

      All any trials here can possibly test for are side effects, nothing else.

    To address the comments above regarding phase 3 and cases in Thailand, if it’s similar at all to the US CDC description of stages of development, you don’t need a large number of actual cases to determine if a vaccine is effective. You can simply jab a large population, in the thousands, with the vaccine and check whether there are enough antibodies in the blood to confer immunity. Since there is data from outside of Thailand for other vaccines that confer immunity, you just need to draw blood and compare to clinical trial results from other countries/vaccines.

    More importantly, the vaccine needs to be checked to see if it has widespread safety under real world conditions e.g. if you ship the vaccine across the country and was in storage for a few days before being put into people in poorer remote regions, will it be as effective as being jabbed into someone one or two days after manufacture and that person is well fed and lives in the city. Not as good as measuring actual decrease in how often corona pops up in the actual population vs control group, but it’s still important to test how well it works in Thailand on Thai people with Thai logistics.

      Sorry, GwaiLo P, but while you’re correct in theory you can’t “just … draw blood and compare to clinical trial results from other countries/vaccines” because that’s not how the other clinical trials were done so the results aren’t there to compare it to directly.

      You might expect them to be, but that’s not how the other companies (at least Phizer, Moderna, and AZ) did their trials, which was why there was no data available on whether the vaccines stopped transmission or not. Those tests weren’t done, and the companies (at least those three) have said that very clearly.

      I don’t know how familiar you are with Thailand’s “poorer remote regions” but Thailand does actually have a very well tried and tested vaccination and vaccine logistics system – not in these sort of ultimate numbers, obviously, but certainly for far more than would be involved in a Ph 3 trial.

    the Anuty guy says animal tests showed “an ability to stimulate immunity”… technically there’s a difference between ‘an ability’ and ‘it positively does stimulate immunity’, but there’s that silly english language thing again.

    So worldwide there are but 0.3% of people currently infected (should you choose to believe highly exaggerated govt and WHO numbers) and in Thailand there are only 0.006% of the population (4225) with ‘active cases’, again given highly erroneous PCR tests, this number is probably also far too high.

    And so there needs to be a vax… why? and you’re going to test these currently sick people where?

    Isn’t it time to stand up to these govt hacks and tell them NO, NO and NO!

      Curious as to where you gathered your stats…?
      Worldwide @0.3%, real number or not, is meaningless if you are living in or going to a place where the rate is much higher… It’s a global world now. the virus can literally travel first class.
      Another thought…, this virus and all its coming variants will do just that, keep coming at an accelerating rate while producing evermore variants unless or until vaccines and vaccination rates Globally get ahead of it and drastically reduce the number of infected ‘human petri dishes’ that allow for the bazillions of ongoing, unrelenting transcriptions, reproduction mistakes and mutation rates therein that occur with viral reproduction.The more people infected, the more viral reproduction occurring and the greater opportunity for larger numbers of mutations that lead to more infectious virus variants unaffected by vaccines.

        Glenn probably gathered his stats from the same place he gathers his claims of what the UN / WHO / Unicef / etc have said, Rob. 😮 😮 😮

    I doubt the Thais could develop a vaccine, or they would have done so by now.
    My theory is that they had to wait until foreigners had a vaccine developed so they could copy the vaccine. They will then claim they invented this vaccine.
    The only skill they show any aptitude for is scamming. They are genius at that!
