Forget the Flu Vaccine – Take Vitamin D!

My most recent blog focused on the new report from the Institute of Medicine (IOM) that stated most people in North America were getting enough vitamin D.  Their research, however, focused only on vitamin D as it pertains to bone health.  Vitamin D does much more than just support healthy bones.  In my opinion, the IOM’s report was way off base and I hope it does not encourage people to stop taking their vitamin D supplements.

As further evidence to this, take this recent research that I ran across today.

A clinical trial led by Mitsuyoshi Urashima and conducted by the Division of Molecular Epidemiology in the the Department of Pediatrics at the Jikei University School of Medicine Minato-ku in Tokyo found that vitamin D was extremely effective at halting influenza infections in children. The trial appears in the March, 2010 issue of the American Journal of Clinical Nutrition (Am J Clin Nutr (March 10, 2010). doi:10.3945/ajcn.2009.29094)

The results are from a randomized, double-blind, placebo-controlled study involving 334 children, half of which were given 1200 IUs per day of vitamin D3.

In the study, while 31 of 167 children in the placebo group contracted influenza over the four month duration of the study, only 18 of 168 children in the vitamin D group did. This means vitamin D was responsible for an absolute reduction of nearly 8 percent. (www.naturalnews.com)

Only 8 percent?  Yes 8 percent!  That may not seem like a lot, but compare this the most recent research available on flu vaccines which states that they only reduce the incidence of the flu by 1%!

I hear some of you.  You’re saying, “That can’t possibly be correct. My doctor said my flu vaccine will protect me from the flu.  If I get the vaccine, I won’t get sick.”

I’ve got the data to back it up.

The Cochrane Collaboration

The Cochrane Collaboration, as described on its own website, is, “…an international, independent, not-for-profit organization of over 28,000 contributors from more than 100 countries, dedicated to making up-to-date, accurate information about the effects of health care readily available worldwide.”

“We are world leaders in evidence-based health care,” the site goes on to say, followed by a quote from The Lancet which states, “The Cochrane Collaboration is an enterprise that rivals the Human Genome Project in its potential implications for modern medicine.” (www.naturalnews.com)

Anyone who is in health care knows about the Cochrane Collaboration and their studies.  They are some of the most trusted studies in the medical world.

Dr. Tom Jefferson, an epidemiologist, worked closely with the Cochrane Collaboration to evaluate the true effectiveness of the flu vaccines.  His findings were truly surprising to those in the traditional medical field.  You may access a great summary by the authors here for free if you are interested in reading it.  I will summarize it below.

Selection Criteria: Randomized controlled trials (RCTs) or quasi-RCTs comparing influenza vaccines with placebo or no intervention in naturally-occurring influenza in healthy individuals aged 16 to 65 years.

Main Results: A total of 50 reports were included in the review.  This included a total of about 70,000 people. They concluded that in ideal situations where the vaccine matched the virus in circulation a 4% reduction in flu rates were obtained.  This means 100 people would need to be vaccinated to prevent 4 cases of the flu.  In average conditions where the vaccine does not match the strain of flu virus there was a 1% reduction.  This means 1 case was prevented for every 100 people who get the vaccine.

Even in ideal conditions where the anticipated viral strain included in the vaccine matches the viral strain in the environment it only produced a 4% reduction!  Remember, the flu vaccine makers try to guess which strain of the flu will be most prevalent each season.  They rarely guess correctly because it’s simply not easy to predict. In fact, the Cochrane Report concluded that it is a…”relatively uncommon circumstance [that the] vaccine match[es] the viral circulating strain.”

That means most people that get the flu vaccine are only afforded a 1% reduction rate in the flu.

The Cochrane Report also warned of manipulation of data and evidence of bias on the part of the pharmaceutical industry:

This review includes 15 out of 36 trials funded by industry (four had no funding declaration). An earlier systematic review of 274 influenza vaccine studies published up to 2007 found industry funded studies were published in more prestigious journals and cited more than other studies independently from methodological quality and size. Studies funded from public sources were significantly less likely to report conclusions favorable to the vaccines. The review showed that reliable evidence on influenza vaccines is thin but there is evidence of widespread manipulation of conclusions and spurious notoriety of the studies. The content and conclusions of this review should be interpreted in light of this finding.

They also went on to conclude:

Our results may be an optimistic estimate because company-sponsored influenza vaccines trials tend to produce results favorable to their products and some of the evidence comes from trials carried out in ideal viral circulation and matching conditions and because the harms evidence base is limited.

Optimistic?! Wow. If a 1% reduction in flu rates is optimistic, I’d hate to see what realistic is!

So back to vitamin D.  Recall that a placebo controlled study recently released in the American Journal of Clinical Nutrition found that vitamin D reduced the rate of flu in children by 8%.  That’s 800% more effective than the vaccines that are available.  I understand that this information steps on a lot of toes, but the numbers don’t lie.

Another plus to vitamin D is that its effectiveness does not rely on matching viral strains and guessing which virus is going to be most prevalent.  It works by regulating your immune system.

Also recall that the IOM says people are getting “enough” vitamin D as long as they are getting 600IU per day.  But this recent study has found added benefit for vitamin D at 1200IU?  Curious.  I think the IOM should reevaluate their stance.

This flu season consider an alternative to the flu shot.  The numbers show that it is not terribly effective.  You’d be better off by eating healthy, exercising and taking a little extra vitamin D.  For adults in the winter I recommend 4,000IU per day.  This will take care of your daily needs as well as protect you from the flu.

    I had a blood draw last week and my vitamin D level was at 105
    I have PPMS
    Is my vitamin D level still too low?

    • Hi Lance –
      A level of 105 is probably a little too high. The research points to optimal levels at around 65ng/ml. That would afford you protection just as well as a level higher than that and it’s been shown to be safe.
