That's different and sounds interesting,saved your recipe to my list. We have a plant growing in our garden that has deep blue flowers on it,my wife say's they eat it for curing cancer, wonder if it's butterfly pea.
Here is the thing the tourist is double vaccinated and tested before and on arrival if that standard is not good enough to open what is ?, After all catching it from these tourist is remote at best sure you can wait to have 80% vaccination but can the people survive until that happens. What is driving all this is irrational fear you want to stay locked up fine just hope the Government support can continue where other countries open up Thailand keeps losing ground to them. Even the COE changes is brand name change with some tweaks at best and will not produce the numbers estimated.
Efficacy is short-lived. The turnaround for Thailand getting supply and people fully vaccinated is going to be like 3 years. By the time everyone is vaccinated the majority of people will be unprotected....d/t waning immunity. The solution: let this virus run rampant. Some 80 year old expats are going to die. Who cares- they were going to die very soon anyways from obesity and the pub.
I understand that about vaxxes. Specific to the flu virus, the reason for annual flu shots is that particular virus is constantly mutating, so even if last year's jab confers lifetime immunity, it will only be against that strain.
But regarding having been infected and the "immunity" it confers, from what I have read on the subject, the anti-body count deteriorates rapidly. This has led to numerous cases of the fully vaxxed post-infection, still succumbing to a second attack.
Fortunately, there are some vaxxes which do confer life-time immunity such as Small Pox and Polio, but there is yet to be one that can do so with any of the Coronaviruses.
