The source as I understand it is SVT, Swedish television website, it says so in the text.
" I’ve been getting most of my statistics from SVT, the Swedish public broadcaster. They had been providing data on the share with antibodies in Stockholm up to a month or two back, when that information discretely disappeared from their website. I wonder why."
Do you really believe this yourself? Then you can easily be scammed by some 'Elon giving away coins' type of scam. Or another possibility could be wishful thinking.

Oh ffs, I live in Sweden, I have seen the graph plenty of times, if you claim it was never there, then you prove it.
