My suspicion is that they have been using it for only a short period of time, or they were not taking the complete protocol religiously. But, do you think its possible that some of what people are taking is fake ivermectin. Maybe like a placebo. My wife and i have been on the complete zelenco protocol for about 7 months now. My mother in law contracted the flu. My wife is around her alot as she has early stage dementia. My wife did catch her flu and all we did was change from the prophylactic regiments to the active case protocol. Her case was very mild and back up and running within two days. I myself have not had any problems. Just trying to make sense of the stories of others saying it didn't help at all. Could it be fake ivermectin or fake stories.
