Vitamin D and Acute Respiratory Infection Study (VIDARIS)
VIDARIS is a double blind randomised placebo controlled trial investigating the effect of vitamin D supplementation on the incidence and/or severity of acute respiratory infections-colds and flu in adults.
- Three hundred and twenty two participants have been recruited from staff and students from the University of Otago Christchurch campus and the Canterbury District Health Board.
- Each month for 18 months (covering two winters), study participants receive either 100,000 IUs of vitamin D or placebo.
- Throughout the study duration participants report any instance of cold or flu-like symptoms (sore throat, cough, runny nose, nasal stuffiness) and fill out symptom severity score sheets for up to 14 days for each reported episode.
- From this, we can determine whether vitamin D supplementation decreases the incidence and/or severity of acute respiratory infections.
- The trial is set to be completed November 2011.
