Sorry, but that's not "data"!
It's pure supposition by someone who's isn't a "specialist", has no training as a virologist at all, isn't a medical doctor, and is a retired A & E nurse who's less medically qualified than a number of those posting here ... who's already been discredited for failing to do his research properly and claiming that others had said things they hadn't!
The idea that "since people will be infected with omicron, they will develop immunity which will prevent further mutations Since available hosts have been infected" has already been shown to be a very unlikely hope since nobody's found any evidence so far that Omicron gives any immunity at all - it's a hope, but that's all it is.
If you think there's any genuine "data" or studies that support that, then PLEASE give a link to any.
I didn't look at much of the video, to be honest, but his views around the 18:00 point that "you can't die twice" and that "people who are vulnerable and people who are dying from Covid are perhaps the people who were dying from the flu in previous years and perhaps the risks are going to be comparable" and "I'm not expecting the deaths from influenza to be added to the deaths from Covid because it's the same group of people and any one individual can only die once and we're not going to lose more people than we otherwise would" give a pretty good indicator of his grasp on reality and the readily available facts.
There are 30 flu related deaths in Thailand every year - last year there were over 20,000 deaths that were Covid related - they're obviously NOT "the same group of people"! ... and if, for the sake of argument, he's correct how does he account for the excess deaths in the UK and world-wide, which is between two and three times the number of 'confirmed Covid-19 deaths'?
Short answer: he doesn't, and ignores it.
He then continues that "all the main brains are now agreeing", but if you look at what the few he quotes actually say that he doesn't misquote and mis-interpret, none of them agree with his view at all. His whole hypothesis that somehow Omicron and flu will merge and only cause the same number of deaths and hospitalisations just defies any sort of logic or medical knowledge - it's like reading what some of the worst offenders from the CCC say when they misrepresent a link.
If I'm not mistaken, I believe these "Islamists" are Thai citizens,
having essentially "...run away from..." nowhere.
Again, I may be totally off the mark here, but this is what I have gleaned from my (limited) readings.
Reinstating Test and Go would also be a positive move, but having cancelled the last one it's a case of "Once bitten...twice shy". International tourists who follow news in Thailand, know that the testing regimen is low. omicron could be huge right now, but without proper testing, no one really knows....
