My Patients Don’t Get the Flu (costs my clinic $11k annually)

Normally, Spring is filled with thoughts of beautiful weather, flowers, and upcoming vacations. We’re not typically thinking about the flu or any seasonal illness.

But this year, everyone is still thinking about Covid-19.

They don’t have a vaccine for Covid-19 yet. But it won’t be long. Some are even saying they may have one by September.

If they do, you can be sure they’ll start hitting you with the heavy push to get the Covid-19 shot right along with the flu shot.

But this past winter should teach you all you need to know about these horrible vaccines.

If you watched the news recently, you probably heard about the “epidemic” of flu and colds we had this past winter. Almost every day, someone would ask me: “Doc, what do you think about the flu vaccine? I can’t afford to get sick. What should I do to protect myself and my family?”

So here’s the answer.

And It Has Nothing To Do With Vaccines

First, flu vaccines work only 1.62% of the time. The Centers for Disease Control (CDC) states that the effectiveness of the flu vaccine is 60%. And that’s what we hear from the talking heads on the TV all the time.

Well that doesn’t sound too bad except for the fact that it is entirely misleading. Here’s why.

It’s a shell game! The flu vaccine contains vaccines for only three viruses: influenza A, influenza B, and seasonal influenza A (or H1N1). But a recent report in the peer reviewed journal The Lancet confirmed that these three viruses cause only 2.7% of all flu cases.

The other 97.3% of flu cases are not caused by these viruses. So what the flu vaccine is actually doing is preventing 60% of 2.7% of all flu cases. This amounts to 1.62%.

When it comes to preventing you from getting the flu, there is a whopping 1.62% chance that the flu vaccine will work for you. In a moment, you’ll be able to compare this to what I will be telling you about some natural anti-flu remedies.

The second problem with the flu vaccines is that they are not safe. Flu vaccines contain mercury – a potent biological toxin. They have caused deaths, auto-immune diseases, seizures, and paralysis.

Remember that in the swine flu epidemic in the early 1980s, more people died from the vaccine than from the swine flu! They rushed that vaccine into use and killed a lot of people. Technological advances may prevent the Covid-19 vaccine from having similar problems. But I don’t want to be their guinea pig. Do you?

Also, ironically enough, flu vaccines commonly have flu-like side effects. Many of my patients who decided to get the vaccine ended up coming to see me. They wanted help with the flu-like symptoms they got from the vaccine.

So other than the fact that they don’t prevent the flu 98.38% of the time, are not safe, and do nothing at all to prevent colds, I guess I have no problems with them.

But fortunately, there is a much better way to protect yourself. And now is the time to prepare.

These Remedies Do Something Vaccines Can’t

First, please understand this. Whether or not you come down with a cold or a flu has very little to do with whether or not you are exposed to it. Teachers, other school workers, and doctors have a very high exposure to viruses. And yet, though many of them do come down with the flu, the majority do not. Why?

Obviously, it’s the immune system. The key to preventing both colds and the flu is to optimize your immune system response. And flu vaccines don’t do that.

Instead of a chemically laden vaccine, why not take natural remedies that enhance the immune system’s response to everything?

Something that not only works for the three types of viruses in the vaccine, but also for the other 97.3% of flu and cold viruses. That way no matter what virus you come in contact with, you will have an optimum response.

There are three remedies that I have found to be unbelievably effective at doing just that. They are so effective that I estimate I lose about $11,000 a year in appointments for flu just by dishing them out.

My staff will verify to you that we almost never have anyone come in for the flu anymore. The only way I know that there is a flu epidemic is by hearing about it. There certainly is no evidence of it in my clinic.

Where to Start

The first remedy is an obvious one – the sunlight vitamin. Vitamin D3 is critical for a healthy immune system response to viruses. When your levels of D3 are suboptimal, you are more likely to come down with the flu. And it’s also going to take you longer to get over it.

Knowing all this, researchers recently published the results of an experiment that looked at how effective taking vitamin D3 is at preventing the seasonal flu.

This is an important study because it is the first one of its kind. It’s a randomized, double-blind, placebo-controlled trial. These are the kind of studies that are hard to argue with, and doctors find the most convincing. The results were amazing.

During the typical flu months of December to April, the researchers gave a group of 334 children either 1,200 units of vitamin D3 a day or a placebo. Of these, 18.6% of the children taking the placebo came down with the flu. Only 10.8% of the vitamin D children got it.

This adds up to a 58% effectiveness for vitamin D in this dose. The CDC states that the effectiveness for the flu vaccine is 60% – essentially the same as for vitamin D. But that’s not all.

Children who have asthma are much more likely to have serious lung complications from the flu. But the results of this study showed that vitamin D protects their lungs.

The results suggest that children who have asthma are six times less likely to have lung complications from the flu if they take vitamin D. All patients with asthma have to be very careful to take enough vitamin D. There is even more to this story.

Vitamin D Works Even Better When Combined With Two Other Natural Therapies

One recent study looked at how effective zinc supplements were at preventing colds. The flu vaccines do nothing to prevent colds. I have talked about zinc and viruses before. Zinc supplements are very effective against viruses.

In this study, the researchers gave 100 healthy children 15 mg of zinc sulfate every day for seven months. They gave another 100 children a placebo. The parents were told to double up on the zinc (or placebo) at the first signs of any cold symptoms, and to continue that dose until the cold was gone.

The results show how effective zinc can be. The number of colds in the zinc group was 70% less than in the placebo group. In those who came down with a cold, the number of days that it took to get over the cold was 69% less in the zinc group. How many side effects? Zero.

The third remedy that has worked well with my patients is the herb echinacea. In 2007, researchers at the University of Connecticut School of Pharmacy in Storrs, Connecticut reported on a meta study they carried out.

A meta study is one in which the researchers examine already published studies and sum up the data in all the studies. This is a good way of finding out what works and what doesn’t.

They evaluated 14 published studies that looked at how effective echinacea is at preventing colds. They found that, “Echinacea decreased the odds of developing the common cold by 58%.” Once again, there were no side effects.

So here is the strategy that I teach my patients to prevent flus and colds (the one that has cost me so much money because they no longer get flus and colds):

1. Do not take the flu vaccine!

2. Take enough vitamin D3 to get your blood levels between 65-75 ng/ml. This amount will vary between different people, but usually averages about 5,000 mg daily. You also can spend time outdoors this summer to help boost your levels. By getting your levels up this high before the next flu season, you’ll be able to protect yourself even better than waiting until winter.

3. For prevention, take a zinc lozenge with echinacea every day. I like Thera Zinc Echinacea Lozenges. They use zinc gluconate. This form is not as effective as acetate, but it’s still effective. You can get these online and at most stores.

And if you still manage to get either a cold or a flu, make sure you have the hydrogen peroxide nebulizer ready to go. I have talked about this in detail in past issues. It is a treatment that I developed five years ago. And it is a virtual slam dunk on viral infections. You can read all about it on my website.
