Highlights of Report in Swedish translated by Google
- Peter Bergman and his colleagues are fortunate to 140 patients daily treatment for one year with either vitamin D (4000 IU) or placebo.
- The study was double-blind: neither the patients - all of which were susceptible to infections - or caregivers knew who belonged to which group before the trial was over.
- The results show that the vitamin D reduced patient discomfort.
- The probability that require treatment with antibiotics during the study period was 63 % lower in the vitamin D group compared with the placebo group, and the incidence of fungal infections including respiratory decreased.
Chart from 2015 publication
Note: if takes ~100 days for the vitamin D levels to plateau (thus no beneift expected until then)

Note RTI in Middle East peaks in the summer, not winter, because they stay away from the hot hot sun
