A Challenge to Fox’s Medical Expert Dr. Marc Siegel

Gary Null PhD, May 4, 2020


Last Friday evening, Fox’s Tucker Carlson Show invited his favorite physician, Dr. Marc Siegel from New York University’s medical school, on his program.  Dr. Siegel is a regular contributor on the COVID19 pandemic for Fox.  He made an emphatic statement that Vitamin C plays no role in the prevention and treatment of coronavirus despite evidence to the contrary.  Instead he emphasized the need for new medications and a vaccine. 

It is expected that a COVID19 vaccine will be fast tracked through the FDA so it becomes available more rapidly.  CNBC News has already reported that White House advisor Dr. Anthony Fauci and other US health officials are collaborating with the drug company Moderna to fast track its COVID19 vaccine that is now in development. In order to expedite medical interventions that are determined to be critical, the FDA permits fast tracking, which lightens the otherwise rigorous clinical trial process and lessens the requirement of long-term assessment to properly evaluate a drug’s or vaccine’s efficacy and safety. According to DrugWatch, many fast tracked drugs have resulted in black box warnings, an FDA flagging of a product as carrying serious adverse risks after its approval and licensure.

Therefore, we want to challenge Tucker’s guest Dr. Siegel. Either they are both uninformed about the peer-review medical literature in the National Library of Medicine and the countless positive patient results from physicians using complementary medicine and Vitamin C therapy for over 5 decades to treat infectious illnesses, including HIV and respiratory infections or they are in denial.  

This may be intentional neglect – making a concerted choice to refuse to acknowledge something in order to avoid contradicting personally held beliefs.

We hope that Tucker and Siegel will be open to interview doctors and patients who have defeated viral infections by non-drug regimens and without vaccination.  There are over 2,600 studies listed in the National Institutes of Health PubMed database specifically addressing Vitamin C therapy and supplementation to prevent and treat infectious diseases; most of these concern respiratory infections.

Below are some of the more important studies, especially regarding the importance of Vitamin C for strengthening the innate and adaptive immune systems. Both of these immune systems are essential for protecting ourselves from COVID19, whereas a vaccine will only act on a single immune system that triggers antibody production.

The possibility that vitamin C affects severe viral respiratory tract infections would seem to warrant further study, especially in light of the recent SARS epidemic.

  • Found that in active people, shortened duration of colds effectively

Vitamin C Is an Essential Factor on the Anti-viral Immune Responses through the Production of Interferon-α/β at the Initial Stage of Influenza A Virus (H3N2) Infection (Seoul National University College of Medicine

Immunology Network, April 2013

Vitamin C is an essential factor for anti-viral immune responses at the early stage of Influenza A infection.





Vitamin C Is an Essential Factor on the Anti-viral Immune Responses through the Production of Interferon-α/β at the Initial Stage of Influenza A Virus (H3N2) Infection (Seoul University College of Medicine)

Immunology Network, April 2013

the infiltration of inflammatory cells into the lung and production of pro-inflammatory cytokines, tumor necrosis factor (TNF)-α and interleukin (IL)-α/β, were increased in the lung. Taken together, vitamin C shows in vivo anti-viral immune responses at the early time of infection, especially against influenza virus, through increased production of IFN-α/β


Extra Dose of Vitamin C Based on a Daily Supplementation Shortens the Common Cold: A Meta-Analysis of 9 Randomized Controlled Trials (Tianjin University of Traditional Chinese Medicine)

The combination of supplemental and therapeutic doses of vitamin C is capable of relieving chest pain, fever, and chills, as well as shortening the time of confinement indoors and mean duration.


A New Mechanism of Vitamin C Effects on A/FM/1/47(H1N1) Virus-Induced Pneumonia in Restraint-Stressed Mice (Pharmacy College, Jinan University, Guangzhou)

Biomedical Research, February 2015

Vitamin C administration significantly decreased expression of susceptibility genes, including mitochondrial antiviral signaling (MAVS) and interferon regulatory factor 3 (IRF3), and increased expression of NF-κB. These findings provide a new mechanism for the effects of vitamin C on influenza virus-induced pneumonia in restraint-stressed mice.



Vitamin C and Immune Function (University of Otago, New Zealand)

Nutrients, November 2017

  • Vitamin C supports epithelial barrier function against pathogens and promotes the oxidant scavenging activity of the skin, thereby potentially protecting against environmental oxidative stress.
    Overall, vitamin C appears to exert a multitude of beneficial effects on cellular functions of both the innate and adaptive immune system. 
  • Vitamin C appears to be able to both prevent and treat respiratory and systemic infections by enhancing various immune cell functions. Prophylactic prevention of infection requires dietary vitamin C intakes that provide at least adequate, if not saturating plasma levels (i.e., 100–200 mg/day), which optimize cell and tissue levels.



Immunomodulatory and Antimicrobial Effects of Vitamin C (University Medicine Berlin)

European Journal of Microbiological Immunology, August 2019

For a few vertebrate species including humans having lost their capacities to synthesize vitamin C themselves during evolution, the uptake of this essential compound from external sources is mandatory in order to prevent from vitamin deficient conditions resulting in severe morbidities

vitamin C is able to inhibit the growth of S. aureus and streptococci even under neutral pH conditions.
