Every nurse I know starting taking quercetin + zinc + vitamins D3 and C (essentially, most of the Zelenko protocol before it was called that) as soon as the plandemic started. Almost 2 years now. They were working long hours and multiple shifts. None of them got sick.
I have been taking all those things (including quercetin)for years. I’m 58 years old, got covid and only knew it because I lost my taste. No other symptoms.
You would have thought that I would have been questioned to find out why my body reacted as well as it did. But of course nobody asked me anything.
