Zelenko’ s prophylactic protocol (vit c, zinc, quercitin) is all my 83 yr old mom has done to keep covid free. She is not vaxxed, and has multiple comorbidities.
She doesn’t really leave her house much, although my daughter did get her on a plane to FL to visit my brother ( during the peak of Delta no less) with no issues.
My 85 year old mom is also unvaccinated and she takes Dr. Zelenko’s formula also - Zinc, Quercetin, Vitamins C & D. So far so good.
During Delta she did test positive one week after I did and, like me, got the antibody treatment and started taking Ivermectin nightly, and supplements daily. She never had another symptom beyond her initial mild headache.
Early/aggressive detection and treatment made the difference between life and death, IMHO. I'm saying this in the past tense, because I believe the medical pandemic is quickly coming to an end, even if the "pandemic of tyranny" persists.
