@deputt it looks like it's not the only cause... I am not V-D, have never taken PCR test.. but I DiD had Cov-d in March 2020. It was horrible but I survived. It took me 1 year to get rid of shortness of breath. My fatigue is still really bad, still pulse around 100, still brain fog.. taking vitamins, minerals, supplements...
No one who is v-d (family members, friends, colleagues...) No one is having any side effects...
I lost 2 jobs because I refused to be v-d...
