My wife and I have been taking C, D3, Zinc, and Quercetin from the start. We both got COVID, were mildly sick but really sailed right through. 60 years old (give or take) and overweight with well-managed high blood pressure. I figure we are immune now from all variants. Still taking all the same stuff.
Same here physically albeit 76. take C D3 Zinc and consume a quart of tonic with quinine once a day. No problems yet. Have Ivervectin on standby from an ER visit if any symptoms show up.
74 here, w various co morbidities. zinc, d3, c, multi, added quercitin per doc after I got the china flu (pretty tired for a week or so). Take horse ivermectin if I felt the need.
