Influenza Vaccine or Vitamin D

      Comments Off on Influenza Vaccine or Vitamin D

The following list of researches suggests that Vitamin D can decrease death from influenza by a significant factor.

If your read the full articles, you may notice, that some researches make an effort to downplay the role of Vitamin D even though the results of their studies are very conclusive. Ask yourself, where is the money.

“The data support the hypothesis that a high vitamin D level, as that found in the summer, acts in a protective manner with respect to influenza as well as pneumonia.”

Randomized trial of vitamin D supplementation to prevent seasonal influenza A in schoolchildren

  • Influenza A occurred in 18 of 167 (10.8%) children in the vitamin D3 group compared with 31 of 167 (18.6%) children in the placebo group [relative risk (RR), 0.58; 95% CI: 0.34, 0.99; P = 0.04].
  • Asthma attacks occurred in 2 children receiving vitamin D3 compared with 12 children receiving placebo
  • Several plausible mechanisms might explain how vitamin D could have reduced the risk of influenza A.

Serum 25-hydroxyvitamin D3 and the risk of pneumonia in an ageing general population

Conclusions These data suggest an inverse effect of serum 25(OH)D3 concentration on the risk of incident pneumonia in the general ageing population.

RE: Epidemic Influenza and Vitamin D

After 3 years, a total of 34 patients reported cold and influenza symptoms, 8in the vitamin D3 group vs. 26 in the placebo group.Only one subject had a cold/influenza while on 2,000 IU of vitamin D.“Vitamin D supplementation, particularly at higher doses, may protect against the ‘typical’ winter cold and influenza.”

Aging Adults and Seasonal Influenza: Does the Vitamin D Status (H)Arm the Body?

  • current influenza vaccines do not offer optimal protection in this population
  • VitD insufficiency increases susceptibility to influenza infection

Vitamin D and Influenza—Prevention or Therapy?

  • The final conclusion is that its significance as an anti-influenza agent remains unresolved, but it does not mean that these considerations are senseless. It is most important to realize that the broad spectrum of vitamin D activity does not exclude such a role
  • the high numbers of winter influenza and pneumonia deaths in Norway were related to low vitamin D levels in this season
  • The positive role of vitamin D in respiratory infections and lung function was confirmed
