  • Farrar responds to Marshall's letter

    John Farrar PhD, Ovando, Montana|Feb 24, 2022

    In my guest column printed in the Jan. 27 and Feb. 3 issues of the Pathfinder, I only addressed the issue about whether the vaccine can prevent transmission – it cannot. My letter said nothing about the efficacy (reducing symptoms) and safety (as yet not fully understood). That parenthetical comment about safety is warranted for two undisputed reasons: 1. Because the full safety packages have not been submitted to the FDA by either Pfizer or Moderna, and 2. The CDC’s own database called the Vaccine Adverse Event Reporting System or VAERS lis...

  • Can the vaccine prevent virus spread to the non-immune? Mucosal immunity and vaccines

    John Farrar PhD, Ovando, Montana|Feb 3, 2022

    Last week in The Pathfinder, I described the Systemic Immune System which mostly serves to protect internal organs and is activated by clinical infections of all sorts including the COVID virus and intramuscular vaccines such as the COVID vaccines. The larger “compartmentalized” mucosal immune system which is integral to the lining (mucosa) of the airways (from the nasal passages to the lungs) was also described. When the airway is exposed to the airborne pathogen (like the COVID virus), the immune cells (lymphocytes) in the airway lining are...

  • Can the vaccine prevent virus spread to the non-immune? Understanding "Compartments" of immunity

    John Farrar PhD, Ovando, Montana|Jan 27, 2022

    It is very awkward for me to do this, but to lend credibility to what I have written below, I will state my background. I have a doctorate degree in immunology from The University of Notre Dame. I spent a career at the National Institutes of Health and in the pharmaceutical/biotechnology industry studying the regulation of the immune response. I have authored or co-authored over 70 scientific research publications on the same. Enough said. In the past two years, I have spent hundreds of hours monitoring and studying scientific reports on the...
