Yes, my Long COVID began shortly after my first Moderna booster in November '21. A much longer story, but the short version is that I worked my way through every local Specialist and all the tests they could throw at me, finally going to Mayo Rochester LC program in August '23. When I asked several Mayo medical professionals if was wrong attributing LC to the booster, their response was consistently "we have heard that from many others". My only positive test for COVID was July '23 and it was a mild 'head cold' like case.

On several Doctor's advice I will not take the vaccine again. The Mayo program is very good and with nearly 5 months of executing their plan I feel better, not 100%, but at least better.
