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.

Study Arms (2)
High Dose Vitamin D
EXPERIMENTAL100,000 IU Vitamin D3 (cholecalciferol) monthly for 12 months. When added to usual care (0-1000 IU Vitamin D per day), averages 3,300-4,300 IU per day.
Standard Dose Vitamin D
ACTIVE COMPARATOR12,000 IU Vitamin D3 (cholecalciferol) or placebo monthly for 12 months. When added to usual care (0-1000 IU Vitamin D per day), averages 400-1,000 IU per day.
Interventions
Usual care of 0-1000 IU vitamin D daily. This is present in both study arms.
