This article is based upon information from several sources, and it does not involve vaccines or drugs to prevent COVID-19 infection. The principles are science-based and the sources are identified, and links to research are included where available. Read the Disclaimers at the end of the article for important information.

First Principles for prevention:

Principle 1 – Avoid Contact
Social distance at least 6 feet when near people you don’t know.  More distance is better. Wear effective masks, with multiple-layer non-woven masks highly recommended. Wash your hands with soap whenever you may have contacted the virus on surfaces, e.g. shopping carts.

Principle 2 – Destroy COVID-19 at the major points of entry, which are the nasal cavities and the salivary glands/mouth.

Principle 3 – increase your immune function through healthy foods and key supplements.

The information provided below is based upon several scientific studies done at Penn State University that show what individuals can do to protect against serious COVID-19 infection using caution and items readily available at your local grocery or pharmacy. The information about the effectiveness and safety of Penn State’s protocol in blocking COVID-19 infection could have been widely published by the NIH and CDC, but their priorities are on vaccines. Soapy water and antiviral mouthwash works to kill the virus.

1) The CDC recommends social distancing when in groups of people that may be carriers of COVID-19 virus.  Social distance has been defined as 6 feet of separation. More is better.

The American Medical Association (AMA) advises those in crowded situations to Wear an effective mask that preferably has two layers.  You can wear at least two layers of a non-woven mask or put a surgical mask in front of a cloth mask.  There are now inexpensive multiple layer non-woven masks, with the center layer specially treated to decrease the spacing of that layer to trap the aerosol SARS-CoV-2 virus more effectively. Single layer cloth masks do not offer much protection due to inability to stop COVID-19 aerosol particles.

The hands and the masks used to cover the mouth and nostrils are potential points of contamination by the virus. The virus has a lipid (fat) coating that makes it vulnerable to soapy water that dissolves the coating and kills the virus. You can wash masks with soapy water and dry them in order to reuse them. If there is NO METAL in the mask, a microwave will dry the mask after washing and add to disinfecting the mask.

2) Penn State University has thoroughly researched how to reduce viral load in the nasal cavities and salivary glands/mouth by irrigating the nose with diluted baby shampoo for 2 minutes and using anti-viral mouthwash for 30 seconds. The article was published in the Journal of American Virology in July, 2021. The procedures described in the university’s research reduce COVID-19 viral load by 99.9%, which is a significant reduction in the risk of infection. Tilting the head back when irrigating the nasal cavities or gargling an antiviral mouthwash to clear the salivary glands/mouth allows for more effective access to the COVID-19 in these areas.

There are alternate methods for reducing the viral load by irrigating the nasal cavities and salivary glands/mouth. A 10% solution of Betadine is commonly available at pharmacies, which is a solution that uses povidone-iodine as the anti-viral agent. It must be diluted to a less concentrated 1% Betadine solution before irrigating the nose. Xlean Nasal Spray with Xylitol is another product that will reduce viral load in the nasal cavities. Xlean is pursuing an EUA from the FDA for this product. Because there is a covering on the virus that consists of a lipid (fat) layer, the baby shampoo dissolves that layer and kills the virus in the nasal cavities.

The research on using providone-iodine to reduce viral load in the nasal cavities and salivary glands was done in India and republished by a division of the NIH. This research examined the effects of dilute providone-iodine in a randomized study that shows this solution lowered the viral load in nasal cavities. It was published by Bioresearch Communications.

3) Wear an efficient mask if you are in a situation that does not allow social distancing. 
The best masks are N95 or K95 masks, but they are expensive.  The most commonly available masks are non-woven fabric and they stop particles that are ~0.3 microns or larger.  COVID-19 that has been converted into an aerosol form is ~0.1 microns. Doubling two non-woven masks has been shown to increase the capture of COVID-19 aerosol particles. Three-layer and four-layer non-woven masks are now available off the internet. Any mask is better than no mask, but cloth masks do not do as an effective job of stopping aerosol virus particles because the woven structures have much bigger spaces than the aerosol virus size. 

4) Taking vitamin D improves the immune response in early infection of COVID-19. This is a direct quote from a scientific study of how vitamin D improves immune function.

Scientific studies of Vitamin-D has been shown to influence both innate and adaptive immunity during infections. It modifies macrophage and monocyte activity, reducing the circulating levels of pro-inflammatory cytokines. Vitamin-D has been also shown to influence human adaptive immune response of T-cells, promoting a humoral Th2 as opposed to the Th1, which is also linked to pro-inflammatory cytokine release. Moreover, it has direct antiviral properties, particularly against enveloped respiratory viruses”.

The Front-Line COVID-19 Critical Care Alliance (FLCCC) recommends 4,000 IU of Vitamin D per day, and 500 to 1,000 mg of Vitamin C twice per day. There is a link to an article by this author titled Your Immune System is Your Best Defense Against Diseases. Links to various sources related to increasing immune function includes the Cleveland Clinic and similar sources.


If you follow these steps, you are at significantly lower risk of experiencing a major COVID-19 infection.

    1. I wear a three layer mask in crowded situations. More importantly, each night I irrigate my nasal cavities with 1% baby shampoo (dissolves the lipid sheath around the virus) and gargle cetylpyridinium chloride mouthwash. This is all in the article you are commenting about. I am glad to get the extra info on D3 and the social distancing.


      1. Three layers…will three layers of picket fences keep mosquitos out? Viruses are tiny compared with the pores in masks. You have a jet of air going through those pores and they will carry viruses straight thru, like leaves in a rushing stream being carried under a bridge.

        I don’t know about the nasal lavage. I expect that my mucosal immunity is strong and protects me. If I were to lavage, I might actually harm my mucosal immunity.

        Mucosal immunity is like the walls in castle defense. Our mucosal membranes carry IgA antibodies which fight viral invaders. It’s likely these antibodies that to some degree are responsible for the truly asymptomatic infections where people never show symptoms. Innate immunity also plays a role.


      2. I don’t have time to respond to all your comments. My article was based upon scientific research with regard to the nasal cavities and salivary glands being the major areas of replication of the virus, and the nasal irrigation addresses one of the major areas of virus replication.

        I am doing what I said in my article. You can do what you want.


      3. According to research by virologists, the Delta mutation has the greatest risk of spreading the virus before there are any symptoms, and perhaps before a test will be positive. I am doing my prevention nightly and if I feel I have serious symptoms, I have a lifetime supply of 12 mg ivermectin that major studies have shown wipe out the virus in 48 hours or less.

      4. More data…

        We used elderberry concentrate, zinc, vit. C, and vit. D when covid hit our house a year ago. We treated within 48 hours of symptom onset and the symptoms cleared within 24 hours. My wife was resistant to taking EC until her fever worsened and she got a severe headache. Then she took my “folk medicine.”

        Early treatment is more important than which antiviral you use. IVM and HCQ are inexpensive, so it makes sense to use them. EC also is inexpensive and it has been used for centuries from America to China to treat colds and flu. EC contains lots of quercetin, which research has shown is a zinc ionophore, like HCQ and IVM.

        The major advantage of EC is that it is over the counter so you can easily prepare for covid.

        Don’t feel like you need to respond to this.

        I always appreciate more data myself.


  1. ““Scientific studies of Vitamin-D has been shown to influence both innate and adaptive immunity during infections. It modifies macrophage and monocyte activity, reducing the circulating levels of pro-inflammatory cytokines.”

    That article is discussing the calcifediol form of vitamin D, which is fast-acting. Supplementing with D3 is dilatory. The half-life of D3 in serum is measured in hours, while calcifediol’s half-life in serum is 29 days.


  2. Glad to see that you are looking at the science and coming up with a plan.

    ” The CDC recommends social distancing ”

    The CDC are a bunch of anti-science crackpots. Even Vinay Prasad has been ranting about the CDC’s long string of blunders.

    “Doubling two non-woven masks has been shown to increase the capture of COVID-19 aerosol particles.”

    Got a link to the study?

    “Vitamin-D has been also shown to influence human adaptive immune response of T-cells, promoting a humoral Th2 as opposed to the Th1, which is also linked to pro-inflammatory cytokine release.”

    Pro-inflammatory cytokines _early_ in infection is a _good_ thing. Later, they can do great harm. But vitamin D helps to reduce inflammation _after_ the covid viral infection has been cleared.

    “The Front-Line COVID-19 Critical Care Alliance (FLCCC) recommends 4,000 IU of Vitamin D per day”

    FLCCC is now recommending the vitamin D analog, calcifediol, instead of D3, which is in line with what researchers and early adopters like me have been saying. I take 20 mcg of calcifediol per day. Australia is producing calcifediol with product names like “Fortaro,” “Ampl-D,” and “D-velop.”

    I have written a post looking at the extensive science behind Elderberry Concentrate.

    Is there any science behind elderberry concentrate?


    1. Thanks for sharing the info about elderberry concentrate. I make a smoothie that includes organic elderberry and hibiscus tea, 20 grams of psyllium and 20 grams of 5-element collagen, ~10,000 IU D3, 10 grams of Lion’s Mane, and about 1/4 teaspoon of Turkey Tail mushrooms I pick.

  3. I had COVID-19 about December 26, 2022. I have a script for ivermectin and got 300 x 12 mg ivermectin from India for a total charge of $92, including $12 for Western Union to covert $80 US into rupees and deliver them to a designated person in India. 12 mg of day 1 and day 4 of symptoms stopped any major issues. I recommend the protocols for any phases of SARS-CoV-2 infection, but I flush my nose with soapy water and use an antiviral mouthwash. The virus has a lipid coating, as I mentioned in the article. I also scrape my tongue when showering. Nobody mentioned that, but I have tried to maintain some common sense when dealing with COVID-19.
