If you took the flu vaccine last year and still got the flu, you are not alone. According to a recent study, by taking the jab, your chances were 27 percent higher of getting the flu than if you hadn’t. ⁽¹⁾

Given the poor track record of last year's flu vaccine, why trust a shot filled with emulsifiers such as polysorbate 80, formaldehyde, and antibiotics to prevent contamination — especially when there may be better, more natural ways to protect yourself from the flu and other seasonal illnesses?

If last year's flu vaccine failure is any indication of what to expect with this year’s round of vaccines, you may want to think twice before getting the jab.

Immune Defense Nasal + Throat Sprays

Dramatically reduce your risk of catching “the next thing going around” with proven, research-based immune-boosting nasal and throat sprays that combine natural flavonoids and soothing botanicals.

Developed by Dr. Peter McCullough, chief scientific officer, this two-step protocol effectively protects and defends against seasonal illnesses — from the common cold to influenza and even COVID-19.

Throat Spray

For maximum benefit: Use this light citrus-mint-flavored spray twice daily (AM and PM).

Ingredients:

• Zinc Bisglycinate⁽²⁾ – Inhibits viral replication with targeted immune support where germs hide out: the upper palate and nasal cavity.
• Quercetin^(3,4) – Powerful antiviral, facilitates zinc transport, and modulates inflammation.
• Perilla (Luteolin)^(5,6) – Strong antiviral action, suppresses inflammation, and enhances interferon production.
• Bee Propolis^(7,8,9) – Antiseptic, anti-inflammatory, antiviral, and prevents spike protein binding.
• CytoGuard™⁽¹⁰⁾ – A natural preservative and microbial suppressor.

Nasal Spray

For maximum benefit:

• Clear nasal passages by gently blowing your nose.
• Prime pump before first use.
• Insert nozzle and spray 1–2 times in each nostril, twice daily (AM & PM).

Ingredients:

• Xylitol⁽¹¹⁾ – Reduces SARS-CoV-2 viral loads and exhibits antiviral properties.
• Erythritol^(12,13) – Antiviral activity and promotes healthy nasal/oral microbiota.
• Saline⁽¹⁴⁾ – Supports mucociliary clearance and reduces overall viral load.
• Grapefruit Seed Extract⁽¹⁵⁾ – Broad-spectrum antimicrobial and blocks spike protein binding.

Be proactive this flu season with botanicals and natural solutions that really work!
