@raphjd You are right that there has been a problem about counting the number of deaths of covid19, because many countries do it differently. And every method has it pro and cons. And some countries' numbers have been too high and some too low because of politics. Still some countries have done better than others. I don't about the changing rules in Scotland, but in Denmark we are now getting the 3. shot a half year after the second. But the covid-vaccine has to be renewed like the flu shot, because the virus is changing and the antibodies get weak after some time.
