I'm glad he recovered. The cough is not uncommon, mine has mostly resolved. Just dealing with seasonal allergies now, which is every year here in Georgia. The 'vaccine' is gene therapy, I would worry more about long term effects from that.I wonder what my 40-year old buddy with no underlying health conditions or co-morbidities would say about this who was on the verge of needing a respirator back in December but because he was "too young" and the hospitals here were rationing ventilators and beds, told him he was out of luck. Fortunately he recovered after the most excrutiating 3 weeks of his life but still has a nagging cough almost 4 months later.
