Coronavirus (Covid-19)

Thai Health Ministry insists Chinese vaccine is effective, despite social media claims

Thailand’s Public Health Ministry insists the Covid-19 vaccine developed by Chinese firm Sinovac, is effective in protecting recipients against the virus. Dr. Supakit Sirilak from the Department of Medical Science was responding to a claim on social media from a man who says he took a rapid test after receiving the CoronaVac vaccine and it showed he’d developed no immunity whatsoever. Supakit says rapid tests would not pick up on immunity levels and that vaccinated people who want to check they’re protected should only do so through standard laboratory tests.

“The immunity develops 2 weeks after you have had your shots. However, the level of immunity differs based on the virus variants. I am not surprised to see that the rapid test could not detect the immunity because it couldn’t reach the point where the immunity is found, which is spike protein. It needs to be done under standard laboratory conditions with a proven method.”

According to a report in the Bangkok Post, Supakit says he himself received the Chinese vaccine in February and developed immunity 2 weeks later. He adds that the Sinovac jab offers a level of immunity of 114 against the original Covid-19 strain, but that drops to less than half against the mutated strain now spreading in Thailand.

Further research into CoronaVac’s efficacy in Chile indicates a near 48% increase in immunity 14 days after the second dose has been administered, but that increases to over 95% after 70 days. According to the Chilean research, the vaccine is 67% effective against symptomatic infection and 80% effective at preventing death.

Meanwhile, Opas Karnkawinpong from Thailand’s Department of Disease Control says he’s confident case numbers will begin to drop over the next 2 weeks, if people adhere to the government’s disease prevention measures, which include a ban on mass gatherings. Pubs, clubs, and other nightlife venues around the country have also been ordered to close, with a ban on the sale of alcohol in restaurants.

    Yawn. These people would be better employed reassuring people than causing panic over nothing and giving them a voice doesn’t help either.

    “According to the Chilean research, the vaccine is 67% effective against symptomatic infection and 80% effective at preventing death.”

    That’s a LOT less than previously claimed and a LOT less than other vaccines around, including even AZ.

    Still having a 20% chance of dying from Covid compared to someone who’s not vaccinated is hardly going to inspire confidence amongst those who are vulnerable.

    Even the Chinese government were admitting there were major problems with the vaccines published performance, personally I wouldn’t take it BUT it’s better than no vaccine at all.

    Can someone explain to me how a rapid test for covid or any test, demonstrates in any way that immunity has developed from a vaccine? As I understand it the test is testing for the virus or particles thereof. So how do you assess a vaccine result by a test for the virus? I get the vaccine may introduce some virus particles to trigger the immune response. Which is antibodies or T Killer cells that will kill the virus. But how is a test for having the infection in any way measuring ones immunity from it? Perplexed? Equally so as to why the good Dr did not explain that?

    the Media is misrepresenting this 50%.

    It was one particular group of healthcare professionals with mild symptoms.

    In general it is 74 to 100% effective.
    One has to wonder at the motivation for this misrepresentation

    Even the Chinese are having to be convinced to take their own vaccines…they are offering coupons, free eggs…and all kinds of stuff because 1) many believe the problem is over, but 2) more and more people are questioning how good the vaccine can be if it was created so quickly.

    I don’t want a Chinese vaccine. No thank you.

    Small Simon, the figures are from Chile where the variants are rampant. Considering this and no related death report, the vaccine is much better than others which could cause death before the virus catches you.

    The China vax efficacy can only be properly determined by officers who are equipped with the GT200 detectors. Fortunately, Thailand still has plenty of GT200 detectors available.

    “Perplexed? Equally so as to why the good Dr did not explain that?”

    He did in the version I’ve got, @Ray.

    Maybe there are different versions, though, as I can’t see any reference to Wilko’s “50%” in the article anywhere.

    Sorry, @Gosport, but you’ve lost me completely.

    How could Chile have said the vaccine was “80% effective at preventing death” if they had “no related death report”?
    If Chile had had “no related death report” then wouldn’t it have been 100% effective?

    Are you talking about the maybe one in a million chance of getting a fatal blood clot if I were a youngish woman (I’m not, BTW)?

    @Gosport, “the vaccine is NOT much better than others which could cause death before the virus catches you”. Even the director of the Chinese CDC came out last week and stated the Chinese vaccines don’t offer a lot of protection and they’ll start looking at adopting the mRNA technology.

    The only question I have is why guys like you become wumaos at every opportunity.

    Chile to their horror has found the Chinese vaccine is only 16% effective after the first dose. They were planning on a longer span between doses in order to increase the number of those vaccinated. They are now in the middle of a huge outbreak which includes a large number of partially vaccinated citizens. Ouch

    They hitched themselves to the Chinese vaccine wagon and now have no choice but to defend it. Thai culture is about face and not losing it. Admitting they made a mistake betting on Chinese vaccines is not acceptable.

    If they had bet on Moderna and Pfizer they would be boasting about their great achievement now.

    They did a great job managing the pandemic and a lousy job managing vaccine acquisition.
