NCT01102374

Brief Summary

This study will test the role of high dose vitamin D supplementation in prevention of acute respiratory infection in older nursing home residents. The investigators hypothesize that residents on high dose vitamin D supplementation will have a lower incidence of acute respiratory infection that those on standard dose vitamin D supplementation.
