I experienced shortness of breath about 6 mos after Moderna 1 vaccine, along with other really nasty symptoms, primarily bottomless fatigue, recurrence of old body infections. 3 old and one new, high ANa. No diagnosis, but group membership info has supported recrrence of very old EBV (mononuceosis) infection. A Mayo Connect member shared her protocol from Neuropath, and started taking 500 mg Lysine, plus 500 mg Olive leaf twice/day helped. I was simultaneusly taking a super prep of Monolaurin (Inspired Nutrition) twice/day. Two months later, no recrrence. Other EBV symptoms still ongoing, but glacially slow improvement with various treatments ongoing.
