If you’ve had the flu recently, you know how miserable it can be. For most people, one bout with it is enough to convince them to run out for a flu shot the following year.
This is exactly what flu vaccines manufacturers would prefer—but there’s actually very little evidence that these shots are the best way to prevent influenza, and plenty of evidence that they carry dangerous risks.
Studies have linked some flu shots to:
- Containing over 25,000 times the EPA’s safe limit for mercury
- With a rise in Alzheimer’s disease
- With degenerative conditions normally blamed on aging.
The newest model, a vaccine called Fluad, no longer contains the mercury-based preservative thimerosal—but plenty of other chemicals that may be even worse, including:
- The heavy metal barium,
- The antibiotic neomycin
- The surfactant polysorbate-80
Despite constant pressure from doctors and drugstores to get your flu shot each and every year, the manufacturer’s own packaging insert recommends that, no one receive more than one shot (not per year, per lifetime).
Worst of all, flu vaccines are not even that effective. In fact, the CDC admitted that the percentage of time that flu shots are effective is significantly lower than what doctors advertise.
They found that getting a flu shot may increase your chances of experiencing a full-blown flu (unvaccinated people sometimes still get the flu, but don’t experience any symptoms at all). A simple blood test will tell you what ailments you might be predisposed to contracting.
“….there’s actually very little evidence that these shots are the best way to prevent influenza, and plenty of evidence that they carry dangerous risks.”
So what’s the alternative?
Protecting against the flu is less about replacing the flu vaccine with a different physical remedy, and more about empowering the immune system to function at its peak.
There are, however, remedies that accomplish this task far more effectively than flu shots—and vitamin D is at the top of the list.
The CDC notes a study published in the Journal of Virology, which found that the flu vaccine (especially when it’s received year after year) can inhibit certain types of immune response. Researchers theorize that this is why vaccinated people can actually be more susceptible to novel sub-types of influenza.
Vitamin D, on the other hand, keeps the immune system in balance and confers natural, effective protection against influenza. One study found that “recent discoveries indicate that vitamin D up-regulates the endogenous antibiotics of innate immunity.
The same study builds on the theory of Dr. John Cannell, who was the first to posit that influenza can be considered a symptom of vitamin D deficiency. A number of other studies now support this model. Its always best to check for vitamin D deficiency.
Researchers consistently find that those with the lowest blood serum levels of vitamin D experience the highest incidence of influenza. This finding was even confirmed by a large study that included a cross-section representative of the entire United States.
Connecting vitamin D deficiency with the flu helps answer many of the tough questions associated with the study of influenza.
- Why do “flu seasons” begin and end so abruptly?
- Why do flu epidemics occur in otherwise unrelated areas of similar latitude?
It seems more and more likely that the sunlight deficiency (and thus the vitamin D deficiency) that characterizes winter months plays a central role.
“Individuals with moderate to severe vitamin D deficiency, supplementation is 10 times more effective than the flu vaccine for preventing influenza.”
Is vitamin D supplementation really more effective?
After an exhaustive review of twenty-five different randomized trials by international research team, they concluded:
- Vitamin D supplementation is indeed more effective than the flu vaccine for preventing influenza.
- Flu shots will prevent 1 out of every 40 cases of the flu (and some experts believe this number is generous),
- While vitamin D supplementation will prevent 1 out of every 33 cases.
These numbers refer to individuals who already have relatively normal blood serum levels of vitamin D.
Individuals with moderate to severe vitamin D deficiency, supplementation is 10 times more effective than the flu vaccine for preventing influenza.
For this reason, it’s extremely important to have your vitamin D levels tested (unless you enjoy getting the flu).
For ideal flu prevention, you’ll want to maintain a level of 45-60 ng/mL of vitamin D year-round—which very often requires supplementation, especially if you live in latitudes above Atlanta, Georgia.
When choosing a supplement:
- Always use vitamin D3 rather than vitamin D2.
- Seek out a highly bioavailable formula (liposomal vitamin D is optimal).
- It’s also essential to take vitamin K2 (ideally in the form of MK-7) with your vitamin D3,
Try to work with a formulation that leverages the synergy between these two nutrients.
