Efficacy of Covid-19 vaccines will drop during mass inoculations: Thai virologist | The Thaiger

Thai virologist Dr. Yong Poovorawan from Chulalongkorn University, has spoken about claims that the efficacy of every vaccine available today, including Covid-19 vaccines, tend to lower after being used in mass inoculations, compared to the findings from the laboratory during human testing trials.

He recommends that people should not rely solely on the vaccines alone because uncertainty will remain during the roll out phase of the new inoculations.

“The best way to protect themselves is to practice basic safety standards as we usually do today… wearing face masks all the time when going outside and in crowded venues, regularly washing hands, and maintain social distancing.”

On his Facebook page, Dr. Young cited the case of Hepatitis B vaccines that claimed between 94-95% efficacy. But after use on mass populations, its efficacy dropped to about 80%. He believes this trend will be the same as Covid-19 vaccines.

“Although the manufacturers claim the vaccines’ high efficacy, that is just the laboratory results. In practice, several variables may cause lower effectiveness of the vaccines.”

He also says that the real effectiveness of Covid-19 vaccines, both the American from Pfizer and the Chinese from Sinopharm will be known soon after the populations of Israel and UAE have been inoculated in large numbers already.

    looks like the quarantine and the other hoops to jump through will be with us for a long time yet then. What’s needed is a super accurate test that can detect the very small viral loads that are present 2 – 3 days after infection, if that can be developed, at least quarantine period could be significantly reduced.

      What’s needed is for our childish media and medical PR shills to grow up and accept that we take small risks every day.

      I invite you to spend the rest of your life in lockdown. That is a right which you most certainly have.

    So lockdowns and mask forever? No thanks.

    Once again, we confront the reality that herd immunity is the future. I’ll take my chances with the 0.2% fatality rate. Polio and the measles are worse than COVID, yet your grandparents lived with these.

    The vaccines are not 100% protective and we’ll have to accept that. If by chance you do get COVID, after being vaccinated, it’s supposed to be less severe. In the west we should have most of the population vaccinated, that wants it, by mid-year. Also better anti-virals treatments will be more readily available and we should be able to bring improved testing to market. Developing countries will take longer.

    Once these tools are in place then we’re in a position to manage this situation and we’ll have a new normal that’ll allow us to reopen fully. People will get sick and die just like with the flu but not in the numbers we have today. We won’t be defenseless like we were the past year.

        I trust the process in place. The trials have occurred. I play the percentages and they’re telling me to move forward and I will. Also I generally tolerate vaccines well and have had them all. Life is full of risks and this is one I’m fully willing to take in about a weeks time.

        There are numerous reasons why this vaccine was developed faster and I’ll list the ones I’m aware of:

        -The technology does not require live virus which is usually grown in eggs and takes time
        -The technology is a platform that you don’t have to rebuild each time from scratch like traditional vaccines
        -The funding for vaccine development and manufacturing was funded up front by governments via advance vaccine purchases and grants. Also entities like the Gates foundation stepped in with funds at critical times to keep the process going. This saved years and freed up everyone to move forward at warp speed. Typically drug and biotech companies provide the funding up front
        -Everyone in the process worked overtime, not regular time. The FDA didn’t take it’s sweet time and probably worked harder than it ever has
        -The studies were more narrow and didn’t answer 10 questions. It answered two so far which is “Will the vaccine keep people from getting sick/severely ill?” and “Is it safe?”. Other questions such as “Will the vaccine prevent spread from the vaccinated?”, “Does it work on kids younger than 16?”, “Is it safe for pregnant women?”, etc. will be answered in time as more studies are conducted. The goal was to stop the illness and death toll.

        I can understand peoples skepticism but it’s usually because of lack of knowledge and/or no tolerance for risk. Everyone has a choice and I expect them to get on board once they see enough of their friends do it without any downside or they see someone they know get severely ill who chose not to vaccinate. If the vaccinated start dropping like flies then I’ll have been wrong but the percentages say that won’t happen.

        You won’t be getting any of our western vaccine, you are in Thailand, you will be getting the Chineses vaccine as the vaccines you have on order from us will not be processed for months yet.

        Or you can come back to England and get two free shots of our vaccine.

        They are safe as my son as a key worker had his first shot three weeks ago, no side affects.

    it s the same sound in every country, fact is it seem they have no idea if the mass immunity will work as everybody in a world wish. so better to prepare all of us. vaccine campaign just start it will take months before to see the result. the last i read about one vaccine is the dose sold are less efficient than the dose used for the trial…….some going to make money on this. well some said at least one more years before to see a change on the travel restriction, i guess it is reasonable.

      I’m against “falange” ( ? ) “coming back to thailand” as I see no reason why one person’s life should be put at risk purely so someone else, whatever country they’re from, can enjoy themselves and have a holiday.

      You evidently think that because you’re a “falange” your holiday is more important than other people’s lives. I don’t, so we’ll just have to disagree on that.

      As for the rest, I despise the absolute dregs of my country who’ve contributed nothing to it in any way, never served in the blue light services or the military in any capacity, but who think that nothing more than an accident of birth gives them something to be proud of.

      If the cap fits, wear it.

      I also think my country’s currently being run into the ground by the biggest group of clowns and incompetents to have done so in living memory, and I see no point in trying to pretend otherwise – not that anyone who’s had anything to do with running the UK in the last twenty years did any better, which is about as sad an indictment of any country as it comes.

      That’s not “hatred”, just disappointment.

    Here’s some common sense and a prediction without bothering about the stats, vaccine and all that Crap. The lockdowns and measures will not stop till pretty much all of the population will bend there knee, begging the goverbements to help them because everybody will be financially destroyed, mentally and physically drained and can’t handle the violence and hopelessness any longer.

    This has been predicted 15+ years ago that we wild go into a dystopian world either by a new world war or virus, go figure

    The Phase III trials of the Pfizer and Moderno vaccines were not “laboratory tests,” as asserted by Dr Young, they were clinical trials involving tens of thousands of subjects. The reduction in risk of acquiring COVID-19 illness in those large trials was 94-95%; the reduction in risk of acquiring serious illness (requiring hospitalization) was 100% (in other words, no vaccinated subject in the large trials became seriously ill). These are empirically observed data, they do no require extrapolation from “laboratory tests,” and it is very unlikely that efficacy will drop to 80%.
    Herd immunity is not a hypothetical, it is a phenomenon which has been observed in many scenarios over the last two centuries. With COVID-19 once 60-70% of a local population have acquired immunity by either infection or vaccination, herd immunity is acquired. This is not unsubstantiated guesswork, it is the application of basic principles of epidemiology. For anyone living in a place where 60+% of the population has either been already infected or vaccinated, the risk of catching COVID-19 is very low.
    COVID-19 is now thought to have a case fatality risk of 0.1-0.2%, which is essentially the same as influenza. In other words, 1 to 2 people of every 1000 who catch COVID-19 will die, the large majority of those being patients with serious pre-existing illness or very advanced age. For anyone who does not have severe chronic illness and is not over about 70 years of age, the risk of severe illness or death from COVID-19 is very low.
    These facts are independent of politics, culture, or national origin. In Sweden, where herd immunity appears to have been achieved, the current incidence of fatality from COVID-19 is 1 per million per day. In other words, 1 person out of each million residents of Sweden dies with COVID-19 each day, and that incidence is dropping toward zero. To put this in context, around the world about 20 people out of each million die every day from all causes: those 20 deaths per million per day took place before SARS-CoV-2 emerged, and those 20 deaths per million per day will continue long after all of us have forgotten about COVID-19.

Pro-democracy activist hit with 6 million baht fine for removal of plants at rally site

Protest leader Panusaya Sithijirawattanakul, aka “Rung”, has been hit with a fine of nearly 6 million baht, after removing plants at Bangkok’s Democracy Monument. Panusaya and 5 other activists have been charged with removing plants placed as decoration around the monument, during a political rally on February 13.

She says Samran Rat police station has ordered her to pay 5.9 million baht as a result of the action. She has also been charged with violation of the emergency decree and various disease control measures. In addition, she faces the serious charge of lèse majesté, following her role in a September 19 rally at the public square of Sanam Luang in Bangkok.

The Democracy Monument rally on February 13 was organised by the People’s Movement, calling for the release of 4 fellow activists. According to a Bangkok Post report, the plants were removed to make way for the rally. Another prominent pro-democracy activist, Panupong Jadnok, aka “Mike Rayong” accuses officials of deliberately planting the trees to create an obstruction. The rally ended in skirmishes with police at the Supreme Court, near Sanam Luang. Protesters were attempting to reach the Bangkok Pillar Shrine, but had their passage blocked by police.

Meanwhile, over the weekend, the government banned mass gatherings, including political protests, ostensibly due to Covid-19 fears. The law has been published in the Royal Gazette, coming into effect on Saturday. However, activists from the People Go network defied the law over the weekend, gathering in protest at the Democracy Monument and calling for the release of the 4 activists held on lèse majesté charges.

Various groups, including Amnesty International and the UN Human Rights Committee, have criticised the government’s use of the country’s lèse majesté law, with Amnesty International describing it as an attempt to silence dissent.

Thailand’s pro-democracy activists ignore emergency decree warnings over weekend

Ignoring a police warning not to violate the emergency decree, pro-democracy activists gathered in their hundreds at Bangkok’s Democracy Monument yesterday. Although the anti-government protests have kicked off again after a 2 month hiatus, the numbers are well down on last years crowds, now measuring more in the hundreds than the thousands.

The Bangkok Post reports that members of the People Go network came together to call for 4 fellow activists to be released from Bangkok Remand Prison. The 4… Anon Nampa, Parit Chiwarak (aka. Penguin), Somyos Prueksakasemsuk, and Patiwat Saraiyaem… are being held on charges of violating section 112 of the Criminal Code (more commonly known as lèse majesté – criticising members of the Thai royal family). All 4 have been denied bail.

Officers from Samran Rat and Songkhram police stations issued statements to say the rally was in violation of the emergency decree. On Saturday, the government used the all-encompassing Covid-19 umbrella to issue a ban on political rallies across 6 provinces, including Bangkok.

Activist Jatupat Boonpattararaksa, aka, Pai Dao Din, ignored a police order for the rally to disperse and proceeded with setting up a stage at the Democracy Monument. He also gave assurances that the gathering would remain peaceful.

“We are not fighting the police deployed in front of us. We are fighting against dictatorship.”

Activists had walked 250 kilometres, from the north-eastern province of Nakhon Ratchasima (also known as Korat), reaching Bangkok’s Kasetsart University on Saturday. Yesterday, they ended their mammoth trek with a walk to the Democracy Monument.

Motorists told to avoid certain areas in Bangkok as protests planned for today | The Thaiger

Bangkok motorists are being told to avoid areas where protests are planned to take place today. Kasetsart intersection, Lat Phrao intersection, Rachaprasong shopping district’s Central World shopping mall and 11th Infantry Regiment barracks in Bangkhen are the sites where demonstrators are set to infiltrate.

The Metropolitan Police Commissioner says he is most concerned about the Lat Phrao intersection, due to the Redem or Restart Democracy group planning to hold a leaderless protest, which has been prone to violence in the past as demonstrated last Sunday. The group is an offset of the Free Youth movement, which is one of the main groups that have been demonstrating against the military-backed government.

The Redem protesters plan to march from the Lat Phrao intersection to the Criminal Court on Ratchadapisek Road, despite a law announced in the Royal Gazette last night which banned protests, mass gatherings and assemblies. The law stated the reasoning was not political, citing fears over Covid-19 instead.

The newly announced law would give the government a wider range of power in enforcing such public gatherings, with law-breakers being subjected to up to a 40,000 baht fine or up to 2 years in jail. The Redem group is expected to demand the release of core Ratsadon leaders and others being held in jail without bail.

The Ratsadon group reached the outskirts of Bangkok yesterday, after a nearly 250 kilometre-long march from the Thao Suranaree statue in Korat province’s Muang district province. But they were met by police who tried to prevent them from marching further into Bangkok, but eventually allowed them to keep marching until they reached the Kasetsart intersection. The group is expected to end the march tomorrow, at Democracy Monument.

Despite the groups’ plans to ignore the recent law that bans protests, police have warned that they will face charges if they defy the new order. 32 companies of anti-riot police have been placed on standby in light of the expected protests taking place in Thailand’s capital today.
