The flu vaccine is a poor example... it has a 50% failure rate. Every year it's the same story "oops, it was a different strain this year"
Im thinking if one takes D3 and Zinc Sulphate they probably wont get the flu.
Pretty sure they wont if taking proohylactic dose of ivermectin or Hydroxychloroquine also.
That is what I am doing...taking the prophylactic dosage of (D3, zinc sulphate daily), (ivermectin horse paste every 2 weeks), and walk about 3 miles daily, even during our Texas snow storm...but, my daughter and wife set me up for the 1st dose for 18 March....
