Why is There Quercetin in VaxxGuard?

VaxxGuard includes quercetin, a bioflavonoid, to limit allergic type responses and minimize reactions to vaccines.  Quercetin is a mast cell stabilizer which means that it keeps mast cells from over-reacting and excreting more histamine than necessary that makes us feel sicker than necessary.


To understand why this is important, we need a basic understanding of our immune system.  When the immune system is faced with an unwanted or unfamiliar protein, virus or bacteria, it will mount a response to isolate it, get rid of it or neutralize it.  This response can be lifesaving and it is exactly what vaccines are intended to help us do.  Vaccines are intended to train our immune system to respond to a viral or bacterial attack and destroy them before they destroy us.   To get an idea of the extent to which mast cells play a role in our lives, see Fig 1 below.

The problem with this protective response by the immune system is that it can become extreme, resulting in us feeling much worse than necessary.  In fact, the main reason that we can feel so sick, with even a minor infection or allergen, is that our bodies are over-reacting to these invaders.  When we over-react, we are also training our bodies to continue to over-react with smaller and smaller stimuli.  Some people can get so sick that it can last for days, weeks and even years.


An article in the Journal of Allergy and Clinical Immunology in 2004 brought the light the possibility of a relationship between certain vaccines (pertussis, measles and BCG) and allergy such as allergic rhinitis and eczema.[1]


Amongst our white blood cells there is one that is known to release histamine (think antihistamines and how they relieve allergy symptoms) and chemotactic factors, that make us feel so sick.  That is the mast cell.  As so aptly stated by Wikipedia: “Although best known for their role in allergy and anaphylaxis, mast cells play an important protective role as well, being intimately involved in wound healing, angiogenesis, immune tolerance, defense against pathogens, and blood–brain barrier function.” When mast cells over-react, they can’t perform their duties of protecting us.  That means we need to protect our mast cells. 


As stated in the package inserts, vaccines in general can cause or be related to a child developing auto-immune diseases, asthma and allergic conditions.  This has aroused much interest resulting in various journal articles and research to ferret out the truth.  In stark contradiction to many scientific journals but in agreement to package inserts, thousands of mothers have reported that their child developed some form of allergic condition or auto-immune disease subsequent to their child receiving a vaccine. 


In 2002, The Pediatric Infectious Disease Journal noted “One possible mechanism is that vaccines or their adjuvants may have direct IgE-potentiating effects.”[2]  In other words, the adjuvants may elicit an allergic reaction in susceptible patients.


VaxxGuard includes quercetin to limit the allergic response and minimize unwanted reactions to vaccinations. 


What about safety?  Its safety profile, as stated by MedicalNewsToday on Jan 14, 2019, was that “Some people reported minor side effects when taking high doses of quercetin, such as 1,000 mg per day, long-term.  Side effects may include: headaches, nausea and tingling sensations.”  These sensations resolve within a day or two. In other words, quercetin is extremely safe.
