Thanks for sharing! He's talking a lot about CFS in general and seems to have a very deep understanding. This definately shouldn't be discarded as some 'anti-vax' lunetic.
He's a researcher and especially towards the middle of the video it gets very nerdy and scientific, talking about behaviour of immune cells. But then at the end he gets much more practical and he mentions 5 specific things that he - as a researcher - thinks that we can do about it.
The microbiome part of it was very interesting.
Of course as someone with vaccine induced long covid/ME/CFS I found his talk especially interesting.
