"The COVID guide: Everything to know about the current state of variants, masking, vaccines and more"
Emphasizing that I am not medically trained, there no mention of vitamin D3 in referenced article. Correction welcome.
Vitamin D - The Sunshine Vitamin (non-FR)
Of course no mention of Vit D...or likely no Ivermectin, or Zinc, or Quercitin mention either. (AFAIK...I did not read the stupid article)
